The early diagnosis and identification of POTS syndrome are of utmost significance. With appropriate treatment, most patients adjust to symptoms and live active lives. The article is a review of POTS syndrome causes, symptoms, treatment, and management with lifestyle modification and presents an easy-to-read review to families, caregivers, and patients.

What is POTS Syndrome?

POTS syndrome and dysautonomia is referred to as autonomic nervous system disorders. POTS syndrome diagnosis is made by an inappropriately high rise in heart rate with position change from lying down to upright. In a healthy person, veins will constrict slightly on standing to avoid blood pooling in the legs. This is not occurring with patients who have POTS.

The body is having difficulty regulating flow, and the heart has to work harder to supply flow to the brain. POTS is observed in children and adults but mainly in females between 15-50 years of age. POTS syndrome in adolescence would normally appear on reaching the adolescent phase, sometimes its symptoms may resolve on reaching adulthood but never fully.

Causes and Risk Factors POTS Syndrome

It is unknown what causes POTS syndrome. It has been speculated that it occurs following some medical event or with some other disease.

  • Genetics: Multiple members of several families have been reported to be affected with POTS, indicating inherited risk.
  • Viral illness: Mononucleosis or influenza has triggered onset of symptoms.
  • Autoimmune disease: Lupus or Sjögren's syndrome put one at risk.
  • Endocrine changes: Puberty, pregnancy, and menopause will exacerbate symptoms.
  • Physical deconditioning: Bed rest or immobilization for several months is most commonly a cause.
  • Other syndromes: Ehlers-Danlos syndrome, fibromyalgia, and chronic fatigue are often seen in association with POTS.
Risk factors are female sex, autonomic disorder in the family, and acute illness. Secondary growth spurt and stress itself also are causes, especially adolescent POTS syndrome.

POTS Syndrome Symptoms

POTS syndrome symptoms vary in each person but have one thing in common: standing. The most frequent are:

  • Increased heart rate: More than 30 beats per minute increase after 10 minutes of standing.
  • Dizziness or lightheadedness: To cause fainting attacks.
  • Severe fatigue: Daily frustration that disrupts work, school, and social functioning.
  • Migraines and mental fogginess: Difficulty concentrating and remembering.
  • Stomach discomfort: Nausea, bloating, and stomach pain are frequent.
  • Heat or cold intolerance: Unable to feel hot or cold like a normal person.
  • Sleep abnormalities: Insomnia or not being able to sleep.
Symptoms always occur in waves, which have been called POTS syndrome flare ups. Flare-ups will usually be precipitated by stress, dehydration, illness, or endocrine changes.

Diagnosis of POTS Syndrome

Since symptoms overlap with other illnesses, diagnosis of POTS syndrome is hard and always secondary. Doctors have to resort to tests, physical examination, and history. Most of all universal of tests is tilt table test, during which patient is tied to tilting bed. Unexplained rise in heart rate without any apparent fall in blood pressure is diagnostic for POTS.

Other tests may be:

  • Blood volume analysis
  • Autonomic nervous function testing
  • Echocardiograms to rule out heart disease
  • Autoimmune marker blood tests
Diagnosis involves symptoms for at least six months with multiple abnormal heart rate response to standing.


Treatment and Management of POTS Syndrome

No sure cure, yet the treatment of POTS syndrome is all regarding symptom relief as well as improving lifestyle. Combination of therapy is usually the best.

Lifestyle Changes

  • Fluid and salt intake: Both in higher amounts to guarantee the circulation and blood pressure levels.
  • Compression hosiery: Stops the blood pooling in the lower extremities.
  • Small frequent meals: Avoids the large meal formation, thereby regulates digestive symptoms.
  • Temperature maintenance: Being cool maintains flare-ups under control.

Diet and Exercise

Increased intake of water, salt supplemented, low protein, and complex carbohydrate is the best POTS syndrome diet. Stay away from caffeine and alcohol to keep the symptom under control. Physical activity in POTS syndrome is also required. Low-impact sports such as swimming, rowing, or recumbent bicycle are most suitable for tolerance. Progressive conditioning enhances blood perfusion and abrogates bursts in heart rate.

Medications

Physician can provide POTS syndrome medications to control symptoms:

  • Beta-blockers: Reduces heart rate.
  • Fludrocortisone: Sparing salt and water by the body.
  • Midodrine: Blood vessel constriction, enhances circulation.
  • SSRIs or SNRIs: Regulates nervous system.
The combination of the best components is different in every patient, thus medical surveillance is needed.

Physical Therapy

Exercise improvement and strengthening keep circulation at normal level and muscles in tonicity. Physical therapy in POTS syndrome exercise can include breathing exercises, stretching, and posture training.

Emotional and Social Support

POTS is cognitively and energetically taxing. Activity of daily living problems are managed by patients and families with support groups, counseling, and education.

POTS Syndrome and Life Expectancy

The better news to share is that POTS syndrome life expectancy is usually excellent. The illness will not typically shorten lifespan. But it incapacitates quality of life and ordinary function. There are some patients with some symptom improvement with the passage of time, but others with chronic symptoms into adulthood.

POTS Syndrome Complications

Though seldom life-threatening, POTS can cause secondary complications:

  • Chronic illness-related depression and anxiety
  • Deconditioning with inadequate physical exercise
  • Reduced school or work attendance
  • Social withdrawal secondary to fatigue and exacerbations
All of these POTS syndrome complications identify the need for strict monitoring and lifestyle management.

Conclusion

POTS syndrome is a complex form of dysautonomia, which upsets circulation and cardiac rhythm. Though the etiology is not understood, early diagnosis and management in general greatly improves the prognosis. Adaptations of lifestyle, medications, treatment, and counseling allow the majority of patients to become stable.

As challenging as it is, POTS does not decrease life expectancy. Minimization of exacerbation, highest level of activity, and normal life can be attained if treated well with the POTS syndrome. Education, awareness, and research increase patient management of this highly underdiagnosed condition.
