Overview

Postural orthostatic tachycardia syndrome (POTS) is a rare condition that is primarily characterized by orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). Orthostatic Intolerance is generally associated with lightheadedness and/or fainting that is typically relieved by lying down again. In people with POTS, these symptoms are also accompanied by a rapid increase in heartbeat.[1] Although POTS can affect men and women of all ages, most cases are diagnosed in women between the ages of 15 and 50.[1] The exact underlying cause of POTS is currently unknown. However, episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period.[1][2] Treatment aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition.[1][3][4]
