If you've just been diagnosed
POTS is one of the more treatable conditions in this family, but the first month matters. Here are the five things that move the needle most, in priority order.
- 01
Get the diagnosis confirmed properly
Ask for an active stand test (NASA Lean) or tilt-table test with heart rate and blood pressure measured lying and standing. Ten minutes can settle months of uncertainty.
- 02
Get the foundations in place
Fluids (2–3L/day), sodium (8–10g/day, with medical guidance), waist-high or abdominal compression. This is the floor everything else builds on.
- 03
Screen for PEM before any exercise plan
If you crash badly the day or two after exertion, the standard POTS exercise approach can harm you. ME/CFS overlap changes the playbook entirely.
- 04
Identify your likely subtype
Neuropathic, hyperadrenergic, or hypovolemic. It guides which medication is most likely to help.
- 05
Build a flare plan and check for the trifecta
POTS clusters with hEDS and MCAS so often clinicians now treat them as one triad. Screening for both changes outcomes.
Questions patients keep asking
The questions that show up over and over in patient communities, with research-backed answers. Click any one to open.
-
Is POTS real?
Yes. POTS has objective, reproducible diagnostic criteria: a sustained heart rate increase of ≥30 bpm within 10 minutes of standing (≥40 bpm in adolescents) without a drop in blood pressure. It's measurable at the bedside in ten minutes, has been formally defined since 1993, and is recognised by every major cardiology and autonomic society.
See the diagnostic criteria → -
Is POTS just anxiety?
No. POTS physically mimics anxiety, racing heart, breathlessness, adrenaline surges, which is why most patients are misdiagnosed with panic disorder for years before someone measures their standing heart rate. Living with a misunderstood, disabling illness genuinely produces anxiety, but treating only the anxiety doesn't resolve the POTS. The heart rate jump on standing is the giveaway.

How is POTS diagnosed?
Most often by an active stand test (also called the NASA Lean Test): you lie down for several minutes, then stand for ten while heart rate and blood pressure are measured. A sustained ≥30 bpm rise without a blood pressure drop strongly supports POTS. A tilt-table test is the more controlled version. Both can be done in a regular clinic.
How diagnosis works → -
Will POTS go away?
Sometimes. Prognosis is more hopeful than for many overlapping conditions. A meaningful share of adolescents whose POTS followed a viral illness improve substantially or recover within a few years. Adults with a clear trigger often improve with consistent management. Many people land on a manageable baseline; full remission is less common but real.
Read on prognosis → -
Can men get POTS?
Yes. About 80% of diagnosed patients are women, but men can and do develop POTS. Male presentations are even more often misread as anxiety, stress, or cardiac issues, so the true ratio is probably less skewed than the diagnosed numbers suggest.
-
Can kids and teenagers get POTS?
Yes, adolescents are one of the most affected groups. Onset commonly follows a viral illness, mononucleosis, or a growth spurt. Adolescent POTS uses a tighter threshold (≥40 bpm rise on standing) and frequently improves substantially as patients progress through their twenties.
-
How much salt and water should I have?
Standard guidance, under medical supervision, is 2 to 3 litres of fluid and 8 to 10 grams of sodium per day, well above normal intake. This must be cleared with a doctor, especially if you have kidney issues or high blood pressure. Electrolyte solutions are usually more effective than water alone.
Read on fluids and salt → -
Should I exercise with POTS?
Usually yes, but POTS-style. Standard upright cardio can be brutal; recumbent or seated exercise (rowing, recumbent bike, swimming) lets you build fitness without provoking the standing heart-rate spike. Structured programs like the Levine (Dallas) and CHOP protocols are designed for POTS specifically. The critical exception is post-exertional malaise, if you have it, pacing comes before progression.
POTS-style exercise → -
What medications help with POTS?
No drug is FDA-approved for POTS, so all are off-label and chosen by subtype. Common options: low-dose propranolol or ivabradine to slow the heart rate, fludrocortisone to expand blood volume, midodrine to tighten blood vessels, pyridostigmine for neuropathic POTS, and clonidine or methyldopa for hyperadrenergic patients. Subtype guides the pick.
Medication options → -
What's the trifecta?
POTS, hypermobile Ehlers-Danlos Syndrome (hEDS), and Mast Cell Activation Syndrome (MCAS) co-occur so often clinicians now talk about them as one triad. Patients with all three need all three managed; treating only the POTS leaves people stuck.
Read about the trifecta → -
Is POTS related to Long COVID?
Yes. POTS has become one of the most common cardiovascular manifestations of Long COVID. A substantial portion of people with persistent post-COVID symptoms meet POTS criteria on testing. The surge of new cases since 2020 has, paradoxically, driven the largest wave of dysautonomia research and clinical attention in decades.
Long COVID overlap → -
Is POTS the same as fibromyalgia or ME/CFS?
No, but they overlap heavily. POTS is defined by an autonomic, postural mechanism. Fibromyalgia is defined by widespread nociplastic pain. ME/CFS is defined by post-exertional malaise. Many patients have two or three of these together, and the overlap matters because ME/CFS in particular changes how POTS exercise should be handled.
Comorbidities → -
Will I faint?
Some POTS patients faint, but most experience presyncope, the feeling of nearly fainting, without actually losing consciousness. Counter-pressure manoeuvres (squatting, crossing legs, tensing the calves) at the first warning sign can often head it off. If you do faint, getting flat fast is the priority; the heart rate problem usually self-corrects within seconds once you're supine.
-
Why are mornings the worst?
Blood volume is at its lowest after a night lying down, your body shifts fluid and you don't drink for hours. The first hours after waking are when most patients have their worst symptoms. Front-loading fluids and electrolytes at the bedside, rising slowly, and using gradual postures (sit on the edge of the bed for a minute) all help.
-
Can wearables help?
Yes, especially for catching flare patterns and tracking standing heart rate. Apple Watch, Oura, Whoop, Fitbit and similar devices make the cardinal POTS signal visible day to day. The missing piece is an interpretation layer that understands what POTS is and connects the data to symptoms. Rox is built to be that layer.
Understanding POTS
POTS is a measurable failure of how the body regulates blood flow when you stand up. It sits in the dysautonomia family, runs in three overlapping subtypes, and most often shows up after a trigger like a virus, surgery, pregnancy, or COVID.
- Defined by a sustained heart rate jump of ≥30 bpm on standing (≥40 bpm in adolescents) without a blood pressure drop.
- Three main subtypes: neuropathic, hyperadrenergic, hypovolemic. They guide which treatments work.
- Not anxiety. Not deconditioning. Objective, reproducible, and bedside-testable in ten minutes.
- Most cases follow a trigger; SARS-CoV-2 is now the most common one.
What it is
POTS stands for Postural Orthostatic Tachycardia Syndrome. In plain terms, it is a condition where the body fails to regulate blood flow properly when a person stands up. Gravity pulls blood toward the legs and abdomen. In a healthy body, blood vessels tighten and the system compensates within seconds. In POTS, that compensation doesn't happen well, so the heart races to make up for it, and the brain doesn't get enough blood.
POTS is a form of dysautonomia, a malfunction of the autonomic nervous system. The autonomic nervous system runs everything you don't consciously control: heart rate, blood pressure, digestion, temperature, pupil size. When it misfires, the effects show up across the whole body, which is why POTS produces far more than just a fast heartbeat.
POTS is not anxiety. It is not deconditioning alone. It is not "all in the head." It is a measurable, reproducible cardiovascular and neurological dysfunction with objective diagnostic criteria.
Disease overview
POTS is a chronic condition affecting an estimated 1 to 3 million people in the United States, with similar prevalence rates elsewhere. Roughly 80% of patients are women, and onset most often occurs between the ages of 15 and 50. Many cases begin after a clear trigger: a viral infection, pregnancy, surgery, physical trauma, or a period of prolonged bed rest. Since 2020, COVID-19 has become one of the most common triggers, driving a large wave of new diagnoses.
The course is variable. Some people, particularly adolescents whose POTS began after a viral illness, improve substantially or recover within a few years. Others have a lifelong condition that needs ongoing management. Most land somewhere in between: a chronic condition that can be brought under reasonable control with the right combination of strategies.
Core symptoms
Racing heart on standing
The defining feature. Heart rate jumps by ≥30 bpm within 10 minutes of standing (≥40 bpm in adolescents). Patients often feel their heart pound just getting out of bed or standing in a queue.
Lightheadedness
Dizziness, a sense of nearly fainting (presyncope), and in some cases actual fainting. Worse on standing, in heat, after meals, and when dehydrated.
Brain fog
Slowed thinking, poor concentration, and word-finding trouble. Driven partly by reduced blood flow to the brain when upright. Often the most disabling symptom for work and study.
Profound fatigue
A heavy, drained exhaustion that is not fixed by sleep. Simply being upright costs energy that healthy people spend without noticing.
Exercise intolerance
Activity that should be easy leaves patients wiped out. Upright exercise is especially hard. This is central to both the experience and the treatment of POTS.
Palpitations and chest discomfort
Awareness of a fast, forceful, or irregular heartbeat. Often frightening, often mistaken for a primary heart problem or a panic attack.
The three main subtypes
POTS is not one single mechanism. Researchers describe at least three overlapping subtypes, and many patients have features of more than one. The categories are still debated, but they matter clinically because they point toward different treatments.
- Neuropathic POTS. Damage to the small nerves that control blood vessel constriction, especially in the legs and abdomen. Blood pools because the vessels do not tighten. Linked to small fibre neuropathy and often to autoimmune mechanisms.
- Hyperadrenergic POTS. An overdrive of the "fight or flight" system. Standing norepinephrine levels are high (often >600 pg/mL). Patients tend to have tremor, anxiety-like surges, high blood pressure on standing, and abnormal sweating. Often more gradual in onset.
- Hypovolemic POTS. Low blood volume. The body simply doesn't carry enough circulating fluid, so there's less to redistribute on standing. Often overlaps with abnormalities in the renin-angiotensin-aldosterone system.
Causes and biological mechanisms
POTS doesn't have a single cause. The strongest contributing mechanisms include:
- Autonomic neuropathy. Damage to the small autonomic nerves, often confirmed by reduced small fibre nerve density on skin biopsy, prevents normal blood vessel constriction.
- Autoimmunity. A growing body of evidence finds autoantibodies against adrenergic and muscarinic receptors in a substantial portion of patients. POTS frequently follows infection and often co-occurs with autoimmune disease, supporting an immune mechanism in many cases.
- Low blood volume and abnormal fluid regulation. Many patients have reduced plasma volume and paradoxically low levels of the hormones that should correct it.
- Connective tissue differences. In patients with hypermobile Ehlers-Danlos Syndrome, overly stretchy blood vessels pool blood more readily.
- Post-viral onset. Epstein-Barr, influenza, and especially SARS-CoV-2 can trigger POTS, likely through a combination of immune activation and autonomic nerve injury.
- Deconditioning as an amplifier. Bed rest and inactivity don't cause POTS on their own in most cases, but they worsen it by shrinking blood volume and weakening the muscles that help pump blood back to the heart.
Related conditions and overlaps
POTS rarely travels alone. It sits at the centre of a now widely recognised cluster with hypermobile Ehlers-Danlos Syndrome (hEDS) and Mast Cell Activation Syndrome (MCAS), often called "the trifecta." It also overlaps heavily with ME/CFS, fibromyalgia, and Long COVID, and is associated with ADHD and autism in around half of patients in some series. Chapter six covers each in depth.
Support for family and loved ones
The hardest thing for the people around a POTS patient to grasp is how variable the illness is. A person can look completely well sitting on a sofa and become unable to stand a few minutes later. They can manage a good day and pay for it for three. This isn't inconsistency or exaggeration. It is the nature of a condition that depends on posture, heat, hydration, hormones, and time of day.
What helps: keeping the patient hydrated and salted, carrying water and snacks, choosing seats over standing, being willing to leave hot or crowded places early, and never treating a faint or a near-faint as drama. What hurts: implying they're anxious, suggesting they'd be fine if they just exercised more without understanding how POTS exercise actually works, and reading a good day as proof the illness is mild.
Think of a healthy autonomic nervous system as a thermostat that adjusts instantly. In POTS, the thermostat is slow, noisy, and over-reactive. The room is never quite the right temperature, and the system burns energy constantly trying to compensate. That constant compensation is why POTS is so exhausting even when nothing dramatic is happening.
The human experience
POTS is profoundly invisible. The cardinal symptom lives inside the body; the disability lives in the things you can't do. Most patients are told they have anxiety for years before someone measures their heart rate on standing.
- The average path to diagnosis is ~4 years and multiple doctors.
- Anxiety is the most common misdiagnosis, and POTS physically mimics panic.
- Strikes most often in the years people are building their lives (15–50).
- Mental health symptoms are usually a consequence of dismissal, not the cause of POTS.
Living with an invisible illness
POTS is profoundly invisible. The cardinal symptom, a racing heart on standing, is felt entirely from the inside. To an observer, a POTS patient sitting down looks like anyone else. The disability lives in what they can't do: stand in a queue, take a hot shower without planning, walk through a supermarket, attend an event that has no chairs. The gap between appearing healthy and being unable to do ordinary things is the central social reality of the illness.
Patients learn early that the world is built for people who can stand. Concerts, weddings, museums, school assemblies, public transport, parties, and even social conventions like greetings are organised around remaining upright. POTS turns these into expensive operations, then turns the recovery into another expensive operation.
Medical gaslighting
POTS is one of the most frequently misdiagnosed conditions in medicine. Because most patients are young women, and because the symptoms include palpitations, breathlessness, and a racing heart, an enormous number are told they have anxiety or panic disorder before anyone checks their heart rate on standing. Studies of POTS patient journeys consistently find an average of around four years and multiple physicians before a correct diagnosis, with many patients told their symptoms were psychological along the way.
The tragedy is that POTS is one of the more objectively measurable conditions in this whole family of illnesses. A ten-minute stand test with a heart rate monitor can strongly suggest it. The diagnosis is missed not because it is hard to detect, but because it is rarely looked for. If you've been told it's anxiety and your heart rate has never been measured lying versus standing, that is the cheapest test in medicine to ask for.
A pattern reported across patient communities, including by a cardiologist who named it: chronically ill patients are often taken less seriously when they arrive at appointments looking put-together. If you wore makeup, dressed up, or smiled at the desk, the clinician sometimes reads that as evidence you're fine. Several patients report deliberately going to appointments visibly unwell, no makeup, no extra effort, and being believed for the first time. None of this should be necessary; it's a clinician-culture problem, not yours.
A more concrete version of the same problem: some patients are "undiagnosed" by new cardiologists who insist POTS requires structural heart damage, and dismiss the standing heart-rate data on their own watches as "emotional distress." Normal EKG, echo, and Holter results do not rule out POTS, they confirm that the heart itself is structurally fine, which is exactly the point. If a clinician deletes a working POTS diagnosis on that basis, it's worth a second opinion from an autonomic specialist before accepting the reversal.
Impact on identity
POTS often strikes during the years when people are building their lives: late adolescence and early adulthood. Patients describe losing the version of themselves who could go to university, hold down a first job, play sport, or simply stand at a party. Rebuilding an identity around a body that can't reliably stay upright is some of the hardest, most private work of the illness.
Many patients describe an early stage of fighting the illness, followed by a slower stage of integrating it. Neither stage is wrong. The point at which the fight becomes a cost rather than a help is something only the patient can judge, and it usually shifts over time.
Social isolation
So much of social life happens standing up or in environments that POTS makes difficult: hot venues, long events, crowded spaces, alcohol, big meals. Patients withdraw not because they want to, but because the cost is too high. Many find their most sustaining community online, among other patients who understand without explanation. The combination of online community and in-person friends willing to choose accessible plans is, for many, the workable middle ground.
Mental health
Anxiety and depression are common in POTS, and the relationship is widely misunderstood. The racing heart, breathlessness, and adrenaline surges of POTS physically mimic anxiety, which is why so many patients are misdiagnosed. Living with a misunderstood, disabling illness also genuinely produces anxiety and low mood. Both deserve care. Neither means the POTS is psychological.
"I was told I had anxiety for three years. Then a cardiologist watched my heart rate go from 70 to 140 the moment I stood up. It turned out my heart wasn't anxious. It was doing exactly what a POTS heart does."
Symptoms, in depth
POTS reaches almost every body system because the autonomic nervous system runs almost everything. Cardiovascular, neurological, GI, thermoregulatory, and the post-meal and morning patterns that point to it.
- Orthostatic tachycardia is the signature; brain fog is often the most disabling.
- Visible blood pooling (acrocyanosis) is a clinical sign, not just cosmetic.
- Heat, large meals, mornings, and dehydration each predictably worsen things.
- Air hunger and palpitations are commonly misread as anxiety.
POTS affects nearly every body system because the autonomic nervous system touches nearly everything. The list below is comprehensive, not a checklist. No patient has every symptom, and symptoms shift with posture, heat, hydration, hormones, and time of day.
When a healthy person stands, the heart rate rises only slightly and settles within a minute. In POTS, standing triggers a sustained jump of 30 bpm or more, often much higher, without a meaningful drop in blood pressure. This single reproducible pattern is what an active stand or tilt-table test is looking for. It's the most objective marker in this whole family of illnesses.
Cardiovascular
Orthostatic tachycardia
The core feature. The heart races on standing to compensate for blood pooling and reduced return to the heart. Heart rate often reaches 120 to 170 bpm simply from being upright.
Palpitations
Awareness of a fast, forceful, or skipping heartbeat. Frequently mistaken for a primary cardiac problem or a panic attack.
Blood pooling
Blood collects in the legs and abdomen on standing. Some patients see their feet and lower legs turn red, purple, or mottled (acrocyanosis), which is a visible sign of the underlying problem.
Chest pain
Common and usually non-cardiac in origin, but always worth investigating the first time it appears.
Standing still is often harder than walking. The core POTS disability for many patients is intolerance of static standing rather than locomotion. Walking helps because muscle contraction in the calves pumps blood back to the heart; standing in a queue removes that pump and lets gravity win. Plans built around "you can walk, so you should be fine" miss the actual disability.
Symptom severity doesn't track simply with peak heart rate. A patient whose standing HR peaks at 130 can feel just as wrecked as someone hitting 180+, depending on subtype, blood volume, cerebral blood flow, and how long the tachycardia is sustained. Comparing numbers between patients (or between days) is not a valid measure of how sick someone is.
Neurological and cognitive
Brain fog
Slowed thinking, poor concentration, word-finding difficulty, and memory lapses. Driven in large part by reduced cerebral blood flow when upright. Often the single most disabling symptom for work and study.
Lightheadedness and syncope
Presyncope (the feeling of almost fainting) is near-universal. Actual fainting occurs in a minority but can be dangerous, particularly on stairs, while driving, or in water.
Headaches and "coat-hanger" pain
Pain across the neck, shoulders, and base of the skull, in the shape of a coat hanger, caused by reduced blood flow to those muscles when upright. Classic for orthostatic intolerance.
Tremor and shakiness
Especially in hyperadrenergic POTS, driven by surges of norepinephrine.
Sensory sensitivity
Light, sound, and sensory overload are common, particularly during symptom flares. The picture overlaps with the central sensitivity seen in fibromyalgia.
Autonomic and systemic
Temperature dysregulation
Poor tolerance of heat, which dilates blood vessels and worsens pooling. Hot showers, hot weather, fevers, and saunas can all trigger severe symptoms. Some patients also struggle with cold.
Sweating abnormalities
Either excessive sweating or an inability to sweat normally, both reflecting autonomic nerve dysfunction.
GI dysfunction
Nausea, bloating, early fullness, constipation, diarrhoea, and gastroparesis (delayed stomach emptying) are common, because the gut is run by the same autonomic nerves. Eating can divert blood to the gut and worsen orthostatic symptoms, which is why large meals often trigger flares.
Bladder dysfunction
Frequent urination, particularly in the morning, partly because the body shifts fluid overnight.
Air hunger and breathlessness
A sense of not getting enough air despite normal oxygen levels. Often mistaken for an asthma or anxiety problem. The cause is usually the heart compensating for poor venous return, not the lungs.
General
Fatigue
Deep and constant. The body spends energy all day simply managing blood flow against gravity.
Exercise intolerance
Activity that was once easy becomes exhausting, particularly anything upright. This is both a symptom and, when handled correctly, part of the treatment.
Sleep disturbance
Difficulty falling asleep, unrefreshing sleep, and a racing heart when lying down in hyperadrenergic patients.
Post-exertional symptoms
In patients with ME/CFS or Long COVID overlap, exertion can trigger a delayed, disproportionate crash known as post-exertional malaise (PEM). This overlap changes how exercise should be approached, and it is the single most important thing to screen for before starting any program. Covered in detail in the treatment chapter.
Diagnosis and treatment
POTS is among the most objectively measurable conditions in this family. A ten-minute stand test can strongly suggest it. Treatment is fluids, salt, compression, a POTS-specific exercise plan, and medications tuned to the subtype.
- Active stand test (NASA Lean) and tilt-table test are the gold standards.
- 8–10g of sodium per day and 2–3L of fluid are foundational, with medical guidance.
- Recumbent-first, graded exercise (Levine/CHOP) is therapeutic, unless PEM is present.
- Propranolol, ivabradine, fludrocortisone, midodrine, pyridostigmine: each fits a different subtype.
The diagnostic criteria
POTS has clear, objective diagnostic criteria, which sets it apart from many conditions in this family. A diagnosis requires all of the following:
- A sustained heart rate increase of at least 30 bpm within 10 minutes of standing or head-up tilt. For adolescents aged 12 to 19, the threshold is 40 bpm.
- No orthostatic hypotension, meaning no sustained drop in blood pressure of more than 20/10 mmHg. The blood pressure stays relatively stable while the heart rate climbs. This is what separates POTS from other forms of orthostatic intolerance.
- Symptoms of orthostatic intolerance present for at least three months.
- Absence of another condition that fully explains the tachycardia (such as dehydration, anaemia, hyperthyroidism, or medication effects).
The active stand test and tilt-table test
POTS is one of the cheapest conditions in medicine to test for. Most of the time, two methods are used.
The active stand test (NASA Lean Test) is the simplest and most accessible. The patient lies down for several minutes while heart rate and blood pressure are recorded, then stands while measurements continue for up to 10 minutes. A reproducible 30+ bpm rise without a blood pressure drop strongly supports POTS. It can be done in a GP office, and a careful version can even be approximated at home with a heart rate monitor.
The tilt-table test straps the patient to a table that tilts them from lying to nearly upright while heart rate and blood pressure are continuously monitored. It removes the muscle pumping that standing normally provides, making the autonomic response easier to isolate. Considered the reference standard, though a positive active stand test is often sufficient.
Tests to find the cause and rule out mimics
- Full blood count. Looking for anaemia, which can cause a fast heart rate.
- TSH and Free T4. Thyroid disease, especially hyperthyroidism.
- Electrolytes and kidney function. Dehydration and salt imbalances.
- ECG and Holter monitor. Primary heart rhythm disorders, inappropriate sinus tachycardia.
- Echocardiogram. Structural heart disease.
- Supine and standing catecholamines. Standing norepinephrine over 600 pg/mL suggests hyperadrenergic POTS.
- Plasma volume or blood volume testing. Hypovolemic subtype, where available.
- Autonomic function testing (QSART, Valsalva). Small fibre and autonomic nerve dysfunction.
- Skin biopsy. Small fibre neuropathy, present in a large subset of patients.
- Morning cortisol. Adrenal insufficiency, which can mimic.
- Autoimmune panel. Associated autoimmune disease and, in research settings, autonomic autoantibodies.
Differential diagnosis
Conditions that can look like POTS or coexist with it:
- Anxiety and panic disorder (the most common misdiagnosis)
- Inappropriate sinus tachycardia
- Orthostatic hypotension and other forms of dysautonomia
- Dehydration and low blood volume from other causes
- Anaemia
- Hyperthyroidism
- Pheochromocytoma (a rare adrenaline-producing tumour)
- Cardiac arrhythmias
- Medication side effects (stimulants, some antidepressants, diuretics)
- Adrenal insufficiency
Unlike most conditions in this family, POTS can be strongly suggested by a single ten-minute bedside test. If you suspect POTS and have been told it's anxiety, asking specifically for an active stand test or tilt-table test with both heart rate and blood pressure measured lying and standing is the most direct path to an answer.
There's no single cure for POTS, but it is one of the more treatable conditions in this family. Most patients improve significantly with a structured combination of fluid and salt loading, compression, a carefully graded exercise program, lifestyle adjustments, and medication where needed. Non-drug strategies come first and remain the foundation even when medications are added.
Fluids and salt
Increasing blood volume is the cornerstone of POTS management. Standard guidance, under medical supervision, is:
- Fluids: roughly 2 to 3 litres of water per day.
- Salt: 8 to 10 grams of sodium per day for many patients, well above normal intake, to help the body hold onto fluid and raise blood volume. This must be cleared with a doctor, especially for anyone with kidney or blood pressure concerns.
- Electrolyte solutions and oral rehydration salts are often more effective than water alone. Branded options (LMNT, SaltStick, SODII) and home-mixed ORS both work; whichever you'll actually drink is the right one.
- Acute rescue: rapidly drinking 300 to 500 ml of cold water can temporarily raise blood pressure and blunt symptoms within minutes (the "water bolus" effect).
Compression
Compression garments reduce blood pooling in the legs and abdomen. Waist-high compression (at least 30 to 40 mmHg) and abdominal compression are more effective than knee-high stockings, because so much pooling happens in the abdomen. Many patients tolerate compression best when introduced gradually and worn during predictably symptomatic times (mornings, hot days, long events).
Exercise, done the POTS way
This is where POTS differs sharply from conditions like ME/CFS. For most POTS patients, a structured, gradual exercise program is genuinely therapeutic, not harmful. The catch is that it must start in positions that don't provoke the heart rate spike, and progress slowly.
- Start recumbent or seated. Rowing machines, recumbent bikes, and swimming let patients build cardiovascular fitness without being fully upright.
- The Levine (Dallas) protocol and the CHOP protocol are structured, published programs designed specifically for POTS, progressing over months from recumbent to upright exercise.
- Strengthen the legs and core, which act as a second pump to push blood back to the heart.
- Progress by tolerance, not by calendar. Pushing too hard too fast causes setbacks.
A significant share of POTS patients also have ME/CFS or Long COVID, where exertion triggers a delayed, disproportionate crash known as post-exertional malaise (PEM). For those patients, standard POTS exercise protocols can cause harm, and pacing takes priority over progressive exercise. Before starting any exercise program, it's essential to establish whether PEM is present. If it is, the approach must change. This is the single most important distinction in POTS exercise management.
Lifestyle adjustments
- Raise the head of the bed by 10 to 15 cm, which helps the body conserve fluid overnight.
- Avoid prolonged standing. When unavoidable, shift weight, cross legs, and tense the calves.
- Eat smaller, more frequent meals, since large meals divert blood to the gut and worsen symptoms.
- Limit or avoid alcohol, which dilates blood vessels and dehydrates.
- Manage heat carefully: cooler showers, cooling vests in summer, planning around hot weather.
- Use counter-pressure manoeuvres (squatting, leg crossing, buttock clenching) at the first sign of presyncope.
Medications
No medication is FDA-approved specifically for POTS, so all are used off-label, chosen based on the suspected subtype and the individual's symptoms.
- Beta blockers (low-dose propranolol). Slow the heart rate. Often first-line, particularly in hyperadrenergic POTS.
- Ivabradine. Slows heart rate without lowering blood pressure. A 2021 randomised trial supported its use, and it has become increasingly favoured when beta blockers are poorly tolerated.
- Fludrocortisone. Helps the body retain salt and water to expand blood volume.
- Midodrine. Tightens blood vessels to reduce pooling. Taken during the day, not before lying down.
- Pyridostigmine. Improves nerve signalling to blood vessels. Useful in neuropathic POTS.
- Clonidine / methyldopa. Calm an overactive sympathetic system in hyperadrenergic POTS.
- IV saline. Used acutely for severe flares; long-term routine use via an indwelling line is debated due to bloodstream-infection risk.
What helps versus what harms
What tends to help
- High fluid and salt intake (with medical guidance)
- Waist-high or abdominal compression
- A graded, recumbent-first exercise program
- Smaller, more frequent meals
- Raising the head of the bed
- Counter-pressure manoeuvres before fainting
- Treating the right subtype with the right medication
- Managing comorbid MCAS, EDS, and ME/CFS
- A doctor who measures your standing heart rate
What tends to harm
- Prolonged bed rest and deconditioning
- Dehydration and skipping salt
- Hot showers, saunas, and heat exposure
- Large carbohydrate-heavy meals
- Alcohol
- Standing still for long periods
- Pushing through exercise when PEM is present
- Being told it's "just anxiety" and left untreated
- Stopping fluids and salt because a good week feels like recovery
Experimental and controversial treatments
This section maps therapies and theories with varying levels of evidence, from "promising and increasingly mainstream" to "popular but unproven." Inclusion is not endorsement. The intent is an honest picture of what patients encounter.
- Immunotherapy (IVIG, plasmapheresis). Emerging, for a subset. For patients with strong evidence of an autoimmune mechanism, IVIG and plasma exchange have shown benefit in case series and small studies. Expensive, with real risks, reserved for severe, refractory, autoimmune-associated cases. Larger trials are needed.
- Ivabradine. Now well-supported. Once experimental for POTS, ivabradine moved toward the mainstream after a 2021 randomised controlled trial demonstrated benefit.
- Mast cell stabilisers and antihistamines. Moderate, for the MCAS subset. H1 and H2 antihistamines and mast cell stabilisers can meaningfully reduce both MCAS symptoms and some POTS symptoms in patients with overlap.
- Low-dose naltrexone (LDN). Anecdotal. Used by some patients for fatigue and possible neuroinflammatory components, especially where ME/CFS overlaps. Cheap and generally well-tolerated; POTS-specific evidence is thin.
- Routine IV saline via an indwelling line. Contested. Acute IV saline clearly helps in a crisis. Ongoing IV saline via a permanent line is controversial because of the serious risk of bloodstream infections.
- Stellate ganglion block. Early. An injection that calms part of the sympathetic nervous system. Explored for hyperadrenergic POTS and Long COVID, with mixed preliminary results.
- Neural retraining and "brain rewiring" programs. Controversial. Programs that frame dysautonomia as a learned nervous system pattern to be unlearned attract both passionate advocates and sharp critics. Some patients report real benefit, plausibly through stress reduction and autonomic calming. Critics note the high cost, the lack of rigorous trials, and the risk of implying the illness is psychological. Worth approaching with clear eyes.
- Cardiac ablation and pacemakers. Generally cautionary. Ablation to slow the heart is widely considered inappropriate for typical POTS and can make things worse, because the fast heart rate is a compensation, not the root problem. Reputable specialists warn against it.
Programs and protocols claiming to cure POTS/ME/CFS through brain rewiring, biofilm clearance, or 50+ supplement stacks are increasingly common online (DNRS, the Born Free Protocol, various YouTube recovery brands). Patient communities consistently flag two issues: none of these have been peer-reviewed or clinically trialed, and several have been associated with worsening when patients abandon foundational care to try them. Some patients find genuine benefit, often through stress reduction and autonomic calming. The cost is real; the evidence is thin; the framing as a cure can be harmful when it doesn't work and patients blame themselves.
Tools, apps, and the kit patients actually use
The POTS toolkit is largely about engineering an environment that respects gravity, heat, and blood volume. What patients consistently report works:
Wearables and heart-rate tracking
- Rox. The companion app this reference is built alongside. Connects your wearable to the rest of the picture (symptoms, fluids, salt, flares, triggers, meds, pacing) and writes the interpretation layer the raw data is missing. Includes a built-in pacing layer, heart-rate ceiling and energy-envelope tracking, so you can pace by the actual numbers instead of guessing. App Store.
- Standing heart-rate logging on an Apple Watch, Garmin, Oura, Whoop, Fitbit, or a chest strap during the morning lying-then-standing routine. The single most useful number you can hand to a clinician.
- Visible armband and app. Continuous HRV-based exertion tracking with zones (Rest, Activity, Exertion) and "pace points" per task, designed for the dysautonomia / ME-CFS / hEDS / fibro cluster. Subscription pricing is steep, community reports are mixed on whether the depth justifies the cost.
Electrolyte products
- LMNT. 1000 mg sodium per stick. Probably the most-used POTS electrolyte; high sodium density and no sugar are the things most patients want.
- SODII. Australian, marketed specifically for POTS; pouches and stick packs at varying sodium levels.
- SaltStick. Capsule format, useful for travel and for people who can't drink another flavoured fluid.
- Liquid IV / NUUN. Lower sodium per serving than LMNT, useful if you tolerate flavour better but need to layer more servings.
- Home-mixed ORS. The cheapest option: water + sodium chloride + a pinch of potassium chloride to a recipe your doctor or dietitian helps you tune.
Several POTS-marketed electrolyte products are flagged by the community for being expensive relative to the sodium they deliver. To hit Dysautonomia International's typical daily-sodium guidance using "a few squeezes" of Buoy drops, patients have calculated you'd need roughly three full bottles a day. Some products have as little as 90 mg sodium per serving, useful for general hydration, far short of POTS needs. Check the sodium-per-serving number, not the marketing.
Compression
- Waist-high or abdominal compression at 20–30 or 30–40 mmHg. More effective than knee-high stockings because so much pooling happens in the abdomen.
- Supacore (Australian, medically patented for POTS) leggings are widely reported to help, including by people who'd given up on knee-highs.
- Footless full tights are easier to wear than full tights and often deliver most of the benefit at a lower price.
- Shower compression. Some patients leave compression on during showers to blunt the hot-water blood-pooling effect that triggers post-shower flares.
- Heads-up: getting tight compression on is itself work. If putting them on uses up half your morning energy budget, easier-to-wear lower-grade or partial garments often deliver more real-world benefit than the "ideal" ones.
Home setup
- Shower stool, IKEA BÄSINGEN is the community favourite because it looks like normal furniture, not medical equipment.
- Head-of-bed elevation by 10–15 cm via bed risers or a wedge to help the body conserve fluid overnight.
- Cooling vest, neck wraps, USB fans for hot rooms, summer, and travel.
- Bedside water bottle with a measured fluid + sodium target front-loaded before you stand up.
- Stool or perching seat in the kitchen so cooking and washing-up aren't standing tasks.
- Mobility aids for high-cost days: a folding cane-seat, a rollator with a seat, or a wheelchair for travel and crowds. Using them situationally is not a sign things are getting worse; it's how you make a wider life possible.
Finding the right clinician
- Dysautonomia International physician finder, the most reliable starting point.
- "Dr. Bayo Clinicians Who Care", a patient-curated list of clinicians by US state and specialty, vouched for by other POTS patients.
- PoTS UK for UK-based clinics.
Living with POTS
What daily life with POTS looks like across mornings, heat, meals, hormones, and the long arc. Prognosis is more hopeful than for many overlapping conditions, especially in younger patients and clear post-viral cases.
- Mornings are usually the hardest; symptoms peak in the first hours after waking.
- Heat, large meals, alcohol, and prolonged standing are predictable triggers.
- Improvement comes from stacking small wins over months, fluids, salt, compression, exercise, the right meds.
- Many adolescents recover substantially within a few years; adults stabilise on consistent management.
Prognosis
The outlook for POTS is more hopeful than for several related conditions, particularly in younger patients. A meaningful share of adolescents whose POTS followed a viral illness improve substantially or recover within a few years. Adults with a clear trigger often improve with consistent management. Some patients have a lifelong condition that waxes and wanes. Very few cases are static; most respond at least partially to the right combination of strategies.
The most reliable predictor of improvement is consistency: sticking with the foundations (fluids, salt, compression, the right exercise plan, the right medications) over months rather than weeks. Stopping the moment a good run begins is the most common reason patients lose ground.
Recovery and improvement stories
Improvement in POTS usually comes from stacking small wins: getting fluids and salt right, finding the compression that works, building back fitness slowly through a structured program, identifying and treating the correct subtype, and managing comorbid conditions. Patients who improve rarely point to one magic intervention. They point to consistency over months.
Self-directed care
Because POTS spans cardiology, neurology, and often immunology and gastroenterology, patients frequently become their own care coordinators. They learn to track standing heart rate, fluid and salt intake, symptom triggers, and medication timing. Many use a wearable to watch heart rate trends and catch a flare building before it lands. This is precisely the kind of work Rox is built to take off your plate.
Daily functioning
- Mornings are often the hardest. Blood volume is lowest after a night lying down, so symptoms tend to peak in the first hours after waking. Front-loading fluids and salt at the bedside, rising slowly (sit, then stand), and using a stool in the shower all help.
- Heat is a major variable. Summer, hot showers, and fevers can turn a manageable week into a difficult one.
- Meals matter. Large meals can cause a post-meal crash as blood diverts to digestion. Smaller, more frequent meals are easier on the system.
- Standing tasks are deceptively expensive. Cooking, showering, queuing, and getting ready can each consume significant energy.
- POTS can disqualify you from donating blood. Mentioning a POTS diagnosis at the American Red Cross typically results in a permanent deferral. Orthostatic intolerance is a fainting risk for donors. Other countries have similar rules.
- The condition is financially heavy. Compression garments, electrolytes, HR monitors, shower stools, and mobility aids add up, and POTS often reduces ability to work. Many patients describe a real trade-off between things that would help and the cost of buying them. Push for clinical letters wherever insurance / supplemental schemes might cover compression and equipment.
- Don't blame everything on POTS. New or worsening symptoms can be something else entirely (lymphoma, sepsis, gum disease driving systemic inflammation, infections that look like a flare). If something doesn't fit your usual pattern, get a second opinion before chalking it up to your existing diagnosis.
Hormonal issues
Many menstruating patients notice their symptoms shift across the cycle, often worsening premenstrually when fluid balance changes. Pregnancy can trigger POTS or change its course in either direction. Perimenopause is another period of fluctuation. Hormonal factors are real and under-studied, and worth tracking alongside other symptoms.
Skin and blood pooling
Blood pooling can produce visible colour changes in the legs and feet: redness, purple mottling, or a blotchy pattern (acrocyanosis) on standing. Some patients also experience flushing, particularly when MCAS overlaps. Cold, pale extremities are common too. None of this is dangerous on its own, but it can be embarrassing in a way that isn't always acknowledged.
Adapting life around the illness
The patients who manage POTS best tend to build their environment around the illness: a stool in the kitchen and shower, a water bottle always within reach, salt on hand, compression worn by default, seats chosen over standing, and schedules that respect the morning difficulty. None of this is giving in. It's the practical engineering that makes a fuller life possible.
POTS rewards the boring stuff. The single most powerful thing isn't a medication or a procedure; it's the patient who actually drinks 3L of water and 8g of sodium every day, wears compression every day, and does their exercise plan every day. The treatments work when the foundations are there.
Comorbidities and the trifecta
POTS sits at the centre of a tight cluster: hypermobile EDS and MCAS form 'the trifecta', and ME/CFS, Long COVID, fibromyalgia, small fibre neuropathy, autoimmune disease and GI disorders all overlap heavily.
- Screen for hEDS and MCAS in every POTS patient; treating only the POTS leaves people stuck.
- Screen for post-exertional malaise (ME/CFS overlap) before any exercise program.
- Long COVID has driven a wave of new POTS cases and a wave of new research.
- Autoimmune disease, GI dysmotility, and migraine are all over-represented.
POTS sits at the centre of a web of overlapping conditions. Treating the POTS while leaving a comorbid condition unaddressed often leaves patients stuck, so recognising the overlaps matters.
The "trifecta": POTS, hEDS, and MCAS
Three conditions co-occur so often that clinicians now speak of them as a triad.
- Hypermobile Ehlers-Danlos Syndrome (hEDS) involves overly stretchy connective tissue, including blood vessels that pool blood more readily, which predisposes to POTS. The wider Hypermobility Spectrum Disorder (HSD) sits next to hEDS on the same continuum. The Ehlers-Danlos Society has the most reliable plain-language overview.
- Mast Cell Activation Syndrome (MCAS) involves overactive immune cells releasing histamine and other mediators, which can both trigger POTS symptoms and cause flushing, hives, GI distress, and reactions to foods and drugs.
- A patient with all three needs all three managed, not just the POTS. Screening for hypermobility (Beighton score) and asking about flushing, hives, and food reactions are quick wins at the first visit.
Among the trifecta cluster, ADHD and autism (often together, often called AuDHD) are over-represented; informal patient-survey estimates run as high as 50%. The mechanism isn't fully understood, but the pattern is real and matters for accommodations, medication choice, and how clinicians ask the history.
Patients in the POTS/EDS/MCAS cluster have repeatedly reported false-positive results on the 4th-generation HIV screening test, with confirmatory testing coming back negative. The exact mechanism isn't established, but it appears to be related to immune activation in the cluster. If you flag positive on an initial screen, this is a known pattern, push for the confirmatory test before drawing conclusions.
ME/CFS
A large share of POTS patients also meet criteria for ME/CFS, whose defining feature is post-exertional malaise (PEM). This overlap is the single most important thing to screen for before starting exercise, because the standard POTS approach of progressive exercise can harm a patient with significant PEM. Where ME/CFS is present, pacing takes priority and the exercise plan must be much gentler and stop-on-symptoms, not push-through.
Long COVID
POTS has become one of the most common cardiovascular manifestations of Long COVID. A substantial portion of people with persistent post-COVID symptoms meet POTS criteria on testing. The surge in cases since 2020 has, paradoxically, brought more research funding and clinical attention to a condition that was long neglected.
Fibromyalgia
Widespread pain, fatigue, and central sensitisation overlap meaningfully with POTS. Many patients carry both diagnoses, and the autonomic dysfunction in fibromyalgia and POTS appears to be related. The fibromyalgia reference on this site goes deeper on the central sensitisation side of the picture.
Small fibre neuropathy
Reduced small nerve fibre density on skin biopsy is found in a large subset of POTS patients, particularly the neuropathic subtype. The same small nerves that sense pain also control blood vessel constriction and sweating, linking POTS to the broader small fibre neuropathy picture.
Autoimmune disease
POTS co-occurs with autoimmune conditions such as Hashimoto's thyroiditis, Sjögren's syndrome, coeliac disease, and lupus at above-population rates. This pattern, alongside the autoantibody findings, supports an autoimmune mechanism in many patients and is part of why some clinicians screen broadly at diagnosis.
Gastrointestinal disorders
Gastroparesis, IBS, and other motility disorders are common, because the gut depends on the same autonomic nerves. GI symptoms can both result from POTS and worsen it through poor nutrition and hydration.
Other overlaps
- Migraine
- Chiari malformation and craniocervical instability (particularly in EDS patients)
- Vitamin and iron deficiencies
- Anxiety and depression (as consequences, and as misdiagnoses)
- Sleep disorders
Research, resources and community
How POTS science has evolved since Da Costa's 'irritable heart' in 1871, the autoimmune hypothesis driving today's work, the Vanderbilt and Mayo research lineage, and the patient organisations worth knowing.
- POTS was formally named in 1993 at Mayo, but the picture has only sharpened since 2020.
- Autoantibodies against adrenergic and muscarinic receptors are the strongest current research direction.
- Long COVID dragged dysautonomia funding into the mainstream after decades of neglect.
- Dysautonomia International, Standing Up to POTS, PoTS UK, and Vanderbilt are the trusted hubs.
The current scientific picture
POTS is best understood today as a heterogeneous syndrome with several underlying mechanisms: autonomic neuropathy, autoimmunity, low blood volume, and connective tissue differences, often in combination. The autoimmune hypothesis, supported by the frequent post-infectious onset and the discovery of autonomic receptor autoantibodies, is one of the most active areas of research. Long COVID has accelerated all of it.
Historical timeline
"Irritable heart" described
Civil War physician Jacob Mendez Da Costa documents soldiers with racing hearts, breathlessness, and fatigue. "Da Costa's syndrome" describes what was almost certainly orthostatic intolerance, repeatedly rediscovered under new names over the next century.
POTS is named and defined
Researchers at the Mayo Clinic, led by Ronald Schondorf and Phillip Low, formally describe and name Postural Orthostatic Tachycardia Syndrome, giving the condition its modern diagnostic shape.
Subtypes characterised
Work from Vanderbilt's Autonomic Dysfunction Center and others defines the neuropathic, hyperadrenergic, and hypovolemic patterns, and establishes the roles of blood volume and norepinephrine.
Vanderbilt exercise research
Studies by Levine and colleagues show that structured, recumbent-first exercise training can substantially improve, and in some cases reverse, POTS, reframing exercise from cause to treatment.
The autoimmune hypothesis gains evidence
Multiple groups identify autoantibodies against adrenergic and muscarinic receptors in POTS patients, strengthening the case that many cases are autoimmune in origin.
COVID-19 transforms the field
SARS-CoV-2 triggers a wave of new POTS cases. Long COVID research drives unprecedented funding and attention into dysautonomia, and post-vaccination POTS is also documented and studied.
Ivabradine randomised trial
A randomised, placebo-controlled trial demonstrates that ivabradine reduces heart rate and improves symptoms in hyperadrenergic POTS, giving clinicians a well-evidenced option.
Guidelines and recognition catch up
Major cardiology and autonomic societies publish consensus statements and expert guidance, and POTS finally begins receiving research investment proportionate to its burden, largely on the back of Long COVID.
Active research directions
- Autoantibody validation. Pinning down which autoantibodies are causal, and developing reliable clinical tests for them.
- Immunotherapy trials. Testing IVIG and related treatments in autoimmune-associated POTS in properly controlled studies.
- Long COVID dysautonomia. Understanding how SARS-CoV-2 damages the autonomic nervous system and whether it can be repaired.
- Wearable biomarkers. Using continuous heart rate, HRV, and posture data to detect, monitor, and predict flares, and to make diagnosis more accessible outside specialist clinics.
- Blood volume and hormonal regulation. Clarifying why the body fails to correct low plasma volume, and how hormones modulate symptoms.
Key sources worth knowing

Content creators worth following
These are the names that come up again and again in the POTS / dysautonomia / EDS / Long COVID corners of Reddit, sorted by what the community actually shares, not by who happens to make videos. The Reddit citation under each card is the thread the recommendation traces back to, so you can see why they're trusted (or contested), not just that they are.
Clinicians and clinician-researchers
One of the few clinicians patients consistently recommend for severe, treatment-refractory cases. Long waiting list, often a "last stop" referral after several specialists. Patients use his published work as a baseline for what a competent POTS workup looks like.
Co-author of the 2025 paper proposing internal tremors in Long COVID as a POTS manifestation, with mast-cell involvement. Patient-readable, prolific on the autoimmune / Long-COVID dysautonomia overlap. The clinician the trifecta community quotes most.
Foundational research on the three subtypes, blood volume, hyperadrenergic norepinephrine, and the recumbent-first exercise programmes that became the Levine and CHOP protocols. If you're trying to map your subtype, their published work is the closest thing POTS has to a canon.
Podcasts
The default POTS podcast in patient communities, with interview-led episodes across clinicians, researchers, and patients. Community caveat: a recent r/POTS thread (197↑) flagged that the host has occasionally platformed unchallenged claims about brain-retraining cures and WiFi sensitivity. Take individual episodes on their own merits rather than as charity endorsement.
The go-to podcast for the trifecta side of the picture, hypermobility, dysautonomia, MCAS. Less polished than the POTScast, more specialist-density per episode. Most-cited episodes cover dysautonomia, EDS-specific clinical edge cases, and women's-health overlaps.
YouTube
Long-form public talks (Google Tech Talks, conference recordings) explaining the trifecta in lay terms. Patients consistently recommend his videos as the single best thing to send to a sceptical family member who doesn't yet take POTS seriously.
Patient-led channel focused on the practical side: compression, electrolytes, flare management, day-to-day adaptations. Cited by recovery-story aggregators as one of the more grounded patient-creator voices in the cluster.
PT-led channel covering nervous-system-aware movement, pacing, and the careful reconditioning approach that fits POTS and overlap conditions (without the standard "just exercise harder" framing that backfires).
Frequent podcast guest on the POTS / MCAS / neuroinflammation overlap from a functional-medicine perspective. Associate Medical Director at Amen Clinics; her conversations on brain inflammation are highly recommended in the cluster, with the usual functional-med caveats around individual claims.
The contested zone, recovery-story creators
A wave of YouTube and podcast creators markets neuroplastic-pain, brain-retraining, and mind-body recovery for POTS, ME/CFS, and Long COVID. The community is genuinely split. Some patients credit them with real improvement. Others have been actively harmed when they were told their illness was a learned pattern and they stopped foundational care to try a programme. Here are the most-shared, with the controversy made explicit so you can decide.
The largest single archive of recovery-story interviews in the chronic-illness world; widely used as a "did anyone like me get better" reference library. Heavily contested. A recent r/cfs thread (193↑) groups her with creators flagged for platforming "Born Free Protocol" style claims, and patients warn that the curated success-story framing can imply the patients who don't recover simply didn't try hard enough.
Short, repetitive daily videos drilling in the brain-retraining frame for chronic pain and dysautonomia. Cited in long-form recovery posts as a useful supplement. Polarising as a sole strategy, particularly for patients with PEM or autoimmune drivers where "just retrain your nervous system" can be actively wrong.
Author and podcast host applying Sarno's TMS framework to chronic illness. A polarising recommendation: patients with significant trauma overlay sometimes find real benefit, while patients with PEM-dominant illness frequently find the "you can cure yourself" framing harmful. Read the room and your own history before trying.
Licensed therapist explaining PRT and pain-neuroscience-education in plain terms. Less salesy than the "guru" end of this category; useful as one input among many if you're exploring the psychological-modulation side. Not a substitute for medical workup or foundational POTS care.
