Postural orthostatic tachycardia syndrome (POTS) is a condition in which a person experiences lightheadedness, fainting and an uncomfortable, rapid increase in heartbeat when standing up from a reclining position and relieved by sitting or lying back down. It may develop after a viral illness, serious infections, medical illness, pregnancy and trauma such as head injury. If you have been experiencing these symptoms, consult your doctor for a timely diagnosis and medication. #KnowTheDisease
