Diabetic neuropathy is a nerve disorder caused by diabetes. Over time, high blood sugar levels from diabetes can damage nerves throughout the body.

  • There are several types of diabetic neuropathy. Peripheral neuropathy reduces the ability to sense pain, touch, temperature and vibration in certain parts of the body. It may also affect movement and muscle strength.
  • Autonomic neuropathy may cause problems with the nerves that control the involuntary functions of the body, such as heartbeat, blood pressure, sweating, digestion, urination and some aspects of sexual function.
  • Focal neuropathy affects a single nerve, most often in the wrist, thigh or foot. It may also affect the nerves of the back, chest and those that control the eye muscles. It often develops suddenly and is the rarest form.
