Overview by M.C.& modification by I.K. USA
to 20 million people in the United States over age 40 have some type of peripheral neuropathy. In many, the impairment is predominantly in small nerve fibers, and the clinical presentation consists of pain, burning, tingling, and numbness in a length-dependent or stocking-glove distribution.Autonomic neuropathy or small fiber neuropathy is caused by damage to the smallest nerves that supply sensory feelings, help regulate your heart rate, blood pressure, perspiration and digestion, among other functions. Neuropathy means damage to your nerves. Autonomic small fiber neuropathy is are often due to diabetes, autoimmune diseases, infections or toxic conditions. Your nerves transmit messages between your brain and your organs. Damage to your autonomic nerves results in faulty communication with your brain and the affected parts of the body .Your nerves are composed of many types of fibers and the smallest fiber is affected by this neuropathy so it is called small fiber neuropathy. The condition is fully and easily reversible.
Signs and symptoms are variable on which nerves are affected but
can range from dizziness to trouble with digestion and urination to
sexual difficulties. Treatment involves addressing the underlying
cause, if possible, and managing the signs and symptoms.
Signs and symptoms of autonomic neuropathy depend on which parts of your autonomic nervous system are most affected. They may include:

- Vaginal dryness and difficulties with arousal and orgasm in women
- Difficulty digesting food (gastroparesis), which can cause diarrhea, constipation, abdominal bloating, nausea, vomiting, heartburn, feeling full after eating little and loss of appetite
