Definition: Autonomic neuropathy occurs when the nerves that control involuntary bodily functions are damaged. This may affect blood pressure, temperature control, digestion, bladder function and even sexual function. The nerve damage interferes with the messages sent between the brain and other organs and areas of the autonomic nervous system, such as the heart, blood vessels and sweat glands. While diabetes is generally the most common cause of autonomic neuropathy, other health conditions even an infection, may be to blame. Some medications also may cause nerve damage.
Symptoms and Treatment: Symptoms vary depending on the nerves affected. They usually develop gradually over years.

Statistics: Statistical analysis on Autonomic neuropathy in Japan were resulted as in patients with diabetes, orthostatic hypotension is usually a result of damage to the efferent sympathetic vasomotor fibers, particularly in the splanchnic vasculature. Patients with orthostatic hypotension typically present with lightheadedness and presyncopal symptoms. Symptoms, such as dizziness, weakness, fatigue, visual blurring, and neck pain, also might be a result of orthostatic hypotension. Many patients, however, remain asymptomatic despite significant falls in BP. Orthostatic symptoms can also be misjudged as hypoglycemia and can be aggravated by a number of drugs, including vasodilators, diuretics, phenothiazines, and particularly tricyclic antidepressants and insulin.
