Most of the process of the body are regulated by the autonomous nervous system. They regulate the breathing rate, blood pressure, heart rate, digestive system, metabolism, urination, the balance of electrolytes, production of saliva, tears & sweat, and sexual response. They are of two types namely sympathetic and parasympathetic divisions. Each division has a specific function and disorders of the autonomic nervous system are called autonomic neuropathies. Autonomic neuropathy might be caused due to various conditions like aging, peripheral nerve disorders, Parkinson disease, viral infections, and injuries to the neck and spinal cord. However, the main cause of autonomic neuropathy is diabetes mellitus. It can be hereditary or acquired. Autonomic neuropathy can manifest in the form of erectile dysfunction in men, urinary retention, dizziness, or lightheadedness, vomiting, urinary incontinence, constipation, or bowel incontinence. It is diagnosed by physical examination, blood pressure changes, ECG, tilt table test, and Valsalva maneuver. Treatments depend upon the organ or the region infected by autonomic neuropathy. The objective of the treatment is to provide relief from symptoms, and treating the underlying condition.
