How is diabetic neuropathy diagnosed?

Diabetic neuropathy is usually presumptively diagnosed clinically by the patient's symptoms, medical history, and physical exam.

Nerve conduction studies measure the speed of nerve signals in the arms and legs, while electromyography measures the electrical discharges produced in muscles. Other tests of nervous system function may be done on some patients. About 45% to 50% of all patients with diabetes are eventually diagnosed with some form of neuropathy.
