Autonomic neuropathy occurs when the nerves that control the body's automatic functions are damaged. Diabetes is the most common cause of autonomic neuropathy, but other causes include other diseases, infections, and certain medications. Symptoms and treatment of this condition depend on the type of nerve damage.

The autonomic nervous system plays an important role in regulating the internal environment, helping the body respond and adapt to changes and impacts from the environment and directly affecting important functions such as heart rate, blood pressure, digestion, respiration, etc.

The autonomic nervous system is divided into two parts, the sympathetic system and the parasympathetic system, which are responsible for regulating physiological processes. To evaluate the autonomic nervous system as well as diagnose the severity of the patient's autonomic nervous system disorder, the doctor will perform tests to evaluate the function of the autonomic nervous system through electromyography.
