Postural Orthostatic Tachycardia Syndrome-POTS
POTS is a complex, multi-system, chronic disorder of the autonomic nervous system characterized by orthostatic intolerance (dizziness when moving from lying to standing or sitting to standing) with excessive heart rate (HR) increase and symptoms on standing while blood pressure is maintained. Orthostatic symptoms improve rapidly after returning to a supine (lying down) position.
While the exact cause of POTS is unknown there is strong evidence that in a large portion of people, POTS is triggered by, viruses, and environmental influences such as:
Viruses (Covid-19, Epstein-Barr Virus, Gastroenteritis)
