Diabetic neuropathy involves damage to nerves because of the presence of high glucose levels in the blood for a prolonged period. Peripheral, focal, autonomic and proximal neuropathy are the different types of diabetic neuropathy. There is perhaps no cure for it, but treatments are available to control the condition. Diabetic neuropathy is diagnosed by performing clinical exams. Nerve conduction studies, electromyography and other nervous system function tests may be done for detection. Approximately 50% of the diabetes patients are diagnosed with at least one form of neuropathy.
