Hypovolemic postural tachycardia syndrome

Common Name(s)

Hypovolemic postural tachycardia syndrome, Postural orthostatic tachycardia syndrome

Postural orthostatic tachycardia syndrome (POTS) is one of a group of disorders that have orthostatic intolerance (OI) as their primary symptom (when an excessively reduced volume of blood returns to the heart after an individual stands up from a lying down position). In POTS, OI causes lightheadedness or fainting, and there is also a rapid increase in heartbeat. Anyone can develop POTS at any age, but the majority of individuals affected are women between the ages of 15 and 50. Episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period. The exact cause is currently unclear. The symptoms of POTS are typically relieved by lying down again. Therapies are targeted at relieving low blood volume or regulating circulatory problems that could be causing the disorder.
