Dysautonomia is actually a broad term used to cover several different medical conditions that cause a malfunction of the Autonomic Nervous System (ANS). The ANS is what controls – what should be – automatic functions of the body. These are things like heart rate, blood pressure, digestion, dilation and constriction of the pupils of the eye, kidney function, and temperature control.
Usually, accompanying the side effects that come from a hampered nervous system, is a constant pain radiating throughout the body. This would be pain like many Fibromyalgia patients have. Dysautonomia can also be a secondary disease in people that have Fibromyalgia, M.S. and Parkinson’s Disease.
