POTS (Postural Orthostatic Tachycardia Syndrome): Living With It

POTS (postural orthostatic tachycardia syndrome) is a disorder of the autonomic nervous system in which standing up makes the heart race by 30 or more beats per minute (40 or more in teens), with lightheadedness, fatigue and brain fog, but without a drop in blood pressure. It mostly affects women aged 15 to 50. There is no single cure, but daily habits such as extra fluids and salt, compression garments and gradual exercise help most people a great deal, often alongside medicines.

Also called: Postural orthostatic tachycardia syndrome, postural tachycardia syndrome, PoTS, orthostatic intolerance

At a glance

What it is
A heart rate rise of 30+ bpm within 10 minutes of standing (40+ in ages 12 to 19), with symptoms, and no fall in blood pressure.
Common triggers
Heat, dehydration, standing still, large carb-heavy meals, alcohol, illness, periods, long bed rest.
Self-care core
2 to 3 liters of fluid a day, extra salt if advised, compression, recumbent exercise.
Medicines
Used when self-care is not enough, such as fludrocortisone, midodrine, low-dose beta-blockers or ivabradine.
Outlook
Many people improve over years, especially teens and those with POTS after a viral illness.

When to get help

Call 911 or go to the ER

  • Chest pain, fainting during exercise, or a heart rate over about 150 at rest with breathlessness
  • Fainting with injury, or not waking up quickly after fainting
  • Sudden weakness, numbness, facial droop or trouble speaking

See a doctor within a day or two

  • Fainting much more often than your usual pattern
  • Unable to keep fluids down for a day because of vomiting or diarrhea
  • New symptoms after starting or changing a POTS medicine, such as a pounding headache lying down (possible high blood pressure)
  • Fast heart rate that persists when lying down, which is not typical of POTS

Book a routine appointment

  • Symptoms stopping you from attending school or work, to review your treatment plan
  • Planning a pregnancy, surgery or long-haul travel
  • Heavy periods, or symptoms that worsen around your period

Usually safe to manage at home

  • A mild flare after heat, a hot shower or a big meal that eases with lying down, fluids and salt

A quick recap of POTS

When you stand, gravity pulls about 500 to 1,000 ml of blood into your legs and belly. Normally the blood vessels tighten and the heart speeds up slightly. In POTS, this response is faulty: blood pools, less returns to the heart and brain, and the heart races to compensate.

This page focuses on daily life and self-management. For the full medical picture, see our pages on postural orthostatic tachycardia syndrome (symptoms and causes) and postural tachycardia syndrome (stand test, tilt test and treatment plan).

POTS vs similar conditions

ConditionOn standingKey difference
POTSHeart rate rises 30+ bpm; blood pressure steadySymptoms ease on lying down
Orthostatic hypotensionBlood pressure falls 20/10 mmHg or moreMore common in older adults and with some medicines
Inappropriate sinus tachycardiaFast heart rate at rest tooNot mainly position-dependent
Vasovagal syncopeSudden drop in heart rate and blood pressureFainting triggered by pain, fear or long standing, with normal heart rate in between

Common POTS triggers

  • Heat: hot weather, hot showers and baths, saunas, and hot rooms widen blood vessels
  • Dehydration: not drinking enough, vomiting, diarrhea, heavy sweating
  • Standing still: queues, concerts, cooking, showering
  • Large meals, especially high in refined carbohydrate, which divert blood to the gut
  • Alcohol, which widens blood vessels and dehydrates
  • Menstruation: many people flare in the days before and during a period
  • Illness, such as viral infections, and recovery from surgery
  • Prolonged bed rest or inactivity, which causes deconditioning and makes POTS worse
  • Poor sleep and stress
  • Certain medicines: diuretics, some blood pressure medicines, some antidepressants and stimulants can affect symptoms

Daily self-management

Fluids and salt

  • Aim for 2 to 3 liters (68 to 100 oz) of fluid a day, unless your doctor advises otherwise.
  • Drink about 500 ml (16 oz) of water quickly before getting up in the morning or before a known trigger. This can raise blood pressure and ease symptoms within 15 to 30 minutes.
  • Many specialists recommend extra salt, often 3 to 10 grams of sodium chloride a day, through salty food, broth, electrolyte drinks or salt tablets. Ask your doctor first, especially if you have high blood pressure, kidney or heart problems.

Compression

Waist-high compression garments or abdominal binders (20 to 30 mmHg or more) reduce blood pooling more than knee socks. Abdominal compression alone helps many people.

Movement and exercise

Exercise is one of the most effective long-term treatments, but it must start lying down or sitting:

  • Months 1 to 3: recumbent bike, rowing machine, swimming and floor-based strength work, starting with short sessions.
  • Then: gradually add upright exercise such as walking or an upright bike.
  • Strengthening the legs and core improves the "muscle pump" that returns blood to the heart.
  • Expect symptoms to worsen briefly in the first weeks. Progress is measured over months.

Physical tricks for symptoms

  • Counter-maneuvers: cross your legs and squeeze, clench buttocks, rise on your toes, or squat when you feel lightheaded.
  • Sit or lie down at the first warning signs rather than pushing through.
  • Get up in stages: sit on the edge of the bed for a minute before standing.
  • Raise the head of the bed by about 10 cm (4 in), which may help the body retain fluid overnight.

Eating

  • Eat smaller, more frequent meals.
  • Reduce refined carbohydrates and sugary foods at large meals.
  • Limit alcohol. Caffeine helps some people and worsens palpitations in others.

Heat

  • Use cool showers or a shower stool, and keep bathrooms ventilated.
  • Use cooling vests, fans and cold drinks in summer.
  • Plan outdoor activities for cooler parts of the day.

Managing a POTS flare

  1. Lie down with your legs raised.
  2. Drink 500 ml (16 oz) of water or an electrolyte drink, and take your usual salt.
  3. Cool down if you are hot.
  4. Use compression.
  5. Rest, but avoid staying in bed for days, which leads to deconditioning.
  6. Treat triggers such as infection, dehydration or heavy periods.

If flares are becoming more frequent or severe, review your plan with your doctor.

Medicines your doctor may suggest

No medicine is FDA-approved specifically for POTS, so all are used off-label:

  • Fludrocortisone or desmopressin to increase blood volume
  • Midodrine to tighten blood vessels (taken during the day, not at bedtime)
  • Low-dose propranolol or ivabradine to slow the heart rate
  • Pyridostigmine to improve autonomic signaling
  • IV saline occasionally for severe flares, though regular infusions are not routinely recommended because of line infections and clots

School, work and travel

  • Students: a school plan can allow water bottles, salty snacks, extra time between classes, elevator use, rest breaks and exam adjustments.
  • Work: ask about seated work, flexible hours, remote work and a cool workspace. In the US, POTS can qualify for reasonable accommodations under the ADA.
  • Travel: drink extra fluids, wear compression, choose an aisle seat and move your legs often.

POTS and pregnancy

Many people with POTS have healthy pregnancies. Symptoms improve for some, worsen for others, often in the first trimester with morning sickness. Fluid and salt needs may change, and some medicines need to be stopped or switched. Plan ahead with your obstetrician and POTS specialist.

Outlook

POTS is often long-lasting but tends to improve. Many teenagers improve considerably by their early twenties, and people whose POTS started after a viral illness often improve over 2 to 5 years. Consistent self-management and graded exercise give the best results.

Frequently asked questions

What triggers a POTS flare?

Common triggers are heat, hot showers, dehydration, standing still, large carbohydrate-heavy meals, alcohol, viral illness, the menstrual cycle, poor sleep and prolonged bed rest. Keeping a symptom diary can help you find your own triggers and plan around them.

How much salt and water should I have with POTS?

Many specialists suggest 2 to 3 liters of fluid daily and extra salt, often 3 to 10 grams of sodium chloride a day. Needs vary, and extra salt is not safe for everyone, especially with high blood pressure or kidney disease. Agree on your targets with your doctor.

What exercise is best for POTS?

Start with recumbent or seated exercise such as a recumbent bike, rowing or swimming, plus leg and core strengthening. Increase duration slowly over weeks, then gradually add upright activity. Structured programs over about 3 months improve symptoms for many people.

Is POTS the same as orthostatic hypotension?

No. In POTS the heart rate jumps on standing while blood pressure stays steady. In orthostatic hypotension, blood pressure falls significantly on standing. Both cause lightheadedness when upright, but they have different causes and treatments.

Can POTS go away?

It can improve substantially or resolve, especially in teenagers and people whose POTS started after an infection. Others have symptoms that come and go for years. Graded exercise, fluids, salt and compression help most people function much better even when POTS persists.
