Nerve damage that occurs in people with diabetes is called diabetic neuropathy. This condition is a complication of diabetes.
In people with diabetes, the body's nerves can be damaged by decreased blood flow and a high blood sugar level. This condition is more likely when the blood sugar level is not well controlled over time.
About one half of people with diabetes develop nerve damage. Symptoms often do not begin until many years after diabetes has been diagnosed. Some people who have diabetes that develops slowly already have nerve damage when they are first diagnosed.
People with diabetes are also at higher risk for other nerve problems not caused by their diabetes. These other nerve problems won't have the same symptoms and will progress in a different manner than nerve damage caused by diabetes.
Symptoms often develop slowly over many years. The types of symptoms you have depend on the nerves that are affected.
Nerves in the feet and legs are most often affected. Symptoms often start in the toes and feet, and include tingling or burning, or deep pain. Over time, nerve damage can also occur in the fingers and hands. As the damage gets worse, you will likely lose feeling in your toes, feet, and legs. Your skin will also become numb.
