Postural Orthostatic Tachycardia syndrome (POTS)

POTS (Postural Orthostatic Tachycardia Syndrome) is a form of dysautonomia where the autonomic nervous system doesn't properly regulate heart rate and blood vessel tone when standing. Upon standing, heart rate increases excessively (30+ bpm, or >120 bpm within 10 minutes) while blood pressure is maintained. This causes symptoms like lightheadedness, palpitations, exercise intolerance, fatigue, brain fog, nausea, and fainting. POTS often affects young women and can be triggered by viral infections (including COVID-19), pregnancy, surgery, or trauma.

CRITICAL: POTS requires diagnosis and management by a cardiologist or autonomic specialist. Diagnosis involves tilt table testing or active standing test. Treatment is multimodal: lifestyle measures (fluid/salt loading, compression garments, exercise reconditioning) are foundational, with medications (fludrocortisone, midodrine, beta-blockers, ivabradine, pyridostigmine) added as needed. Underlying causes (autoimmune, small fiber neuropathy, mast cell activation, EDS) should be investigated. These supplements support the foundational salt/fluid strategy and address common deficiencies but are NOT replacements for comprehensive medical management.

* Electrolytes/Sodium - Salt and fluid loading is the cornerstone of POTS management. Increasing salt intake to 3-10g daily (with 2-3L of fluids) helps expand blood volume and reduce symptoms. Salt tablets or electrolyte drinks are commonly used.

* Vitamin D deficiency is very common in POTS patients and may affect symptom severity.

* Iron deficiency is common and can worsen symptoms. Target ferritin levels >50-70 ng/mL.

* Vitamin B12 deficiency can cause autonomic neuropathy and should be corrected.

* Magnesium supports cardiovascular function and may help with palpitations.

* Coenzyme Q10 may help with the profound fatigue common in POTS.

* Omega-3 Fatty Acids support cardiovascular health.

* Potassium is important when increasing sodium intake significantly.

Expected timeline: Salt/fluid loading can provide relief within days. Exercise reconditioning takes 3-6 months to show significant benefits. Many patients improve over 1-5 years, though symptoms may wax and wane.
