Diabetic neuropathy is a kind of nerve damage that can happen if you have diabetes. High blood sugar (glucose) can injure nerves all over your body. Diabetic neuropathy most often damages the nerves in your legs and feet.
Depending on the affected nerves, symptoms of diabetic neuropathy can range from pain and numbness in your legs and feet to problems with your digestive system, urinary tract, blood vessels and heart. Some people have mild symptoms. But for others, diabetic neuropathy can be quite painful and disabling.
Diabetic neuropathy is a common and serious complication of diabetes. However, you can often prevent diabetic neuropathy or slow its progress with tight blood sugar control and a healthy lifestyle.
