What Causes POTS?
POTS is a heterogeneous (meaning it has many causes) group of disorders with similar clinical manifestations.1,4 POTS itself is not a disease; it is simply a cluster of symptoms that are frequently seen together. This is why the 'S' in POTS stands for "Syndrome." Since POTS is not a disease, it is fair to say that POTS is caused by something else. However, figuring out what is causing the symptoms of POTS in each patient can be very difficult, and in many cases, patients and their doctors will not be able to determine the precise underlying cause. When doctors cannot pinpoint the underlying cause of a patient's POTS, it may be called Primary or Idiopathic POTS.1 Idiopathic simply means "of an unknown origin."
While researchers are still working to identify the root causes and pathology of POTS, there are several underlying diseases and conditions that are known to cause or be associated with POTS or POTS like symptoms in some patients. This is a partial list:
-Amyloidosis;1
-Autoimmune Diseases such as Autoimmune Autonomic Ganglionopathy, Sjogren's Syndrome, Lupus, Sarcoidosis, Antiphospholipid Syndrome;1,3, 22

-Diabetes and pre-diabetes
-Ehlers Danlos Syndrome - a collagen protein disorder than can lead to joint hypermobility and "stretchy" veins;3,12

-Infections such as Mononucleosis, Epstein Barr Virus, Lyme Disease, extra-pulmonary Mycoplasma pneumonia and Hepatitis C;1,2,3,4,10,11
-Multiple Sclerosis;14
