Answer to Question 1
Diabetic neuropathy most often involves the peripheral nerves (peripheral neuropathy) or nerves that control body organs and glands (autonomic neuropathy). Peripheral neuropathy-the most common form of neuropathy in diabetes-may be experienced as pain, numbness, or tingling in the hands, feet, and legs or weakness of the limbs. Pain and cramping in the legs are often severe during the night and may interrupt sleep. Peripheral neuropathy also contributes to the development of foot ulcers because cuts and bruises may go unnoticed until wounds are severe. Autonomic neuropathy may be evidenced by sweating abnormalities, disturbed bladder function, erectile dysfunction, delayed stomach emptying (gastroparesis), constipation, and cardiac arrhythmias. Neuropathy occurs in about 50 percent of patients with diabetes; the extent of nerve damage depends on the severity and duration of hyperglycemia.
