Postural orthostatic tachycardia syndrome (POTS) is a condition that affects millions of people all over the world. There are three main types of POTS: neuropathic, hypovolemic, and hyperadrenergic. Some of the main symptoms of POTS are shakiness, dizziness, fatigue, and elevated heart rate and mostly occur when your body position changes. POTS is hard to diagnose because of the variety of symptoms and the range of times it can occur. The main way to diagnose POTS is by using the tilt table test. Doctors commonly recommend exercise, eating healthy, and avoiding things that can trigger the symptoms, but there are also medications that can be taken to help with some of the symptoms. Some of the more common medications used to treat the symptoms of POTS are fludrocortisone, pyridostigmine, midodrine, and beta blockers. There is a lot of research to be done into the causes of POTS and how to treat it better. One possible area of research is blood circulation and how to increase it either with drugs, such as pentoxifylline, or without the use of medication, such as using compression garments.
