Hyperadrenergic POTS (Postural Orthostatic Tachycardia Syndrome) Dysautonomia

Hyperadrenergic POTS is a form of dysautonomia. It affects the body's autonomic nervous system, which controls things like heart rate, blood pressure, body temperature and many more things. Postural changes (going from laying to sitting to standing) can have huge effects on a person with dysautonomia. This is what happens to me simply by standing up.
