What can be done to prevent the disease?

A 10-year study by the National Institute of Diabetes and Digestive and Kidney Diseases showed that blood glucose control is key in preventing diabetic neuropathy. People who kept their blood glucose levels as close to the normal range as possible were able to delay the onset and progression of neuropathy.

Diabetic neuropathy is also more common in people who are more than 40 years old. It is more likely in those who smoke. Heredity also plays a role, since some people are more susceptible to nerve damage than others.

What are the long-term effects of the disease?

If diabetic neuropathy is not treated effectively, it can have devastating effects. Muscles may waste and become weak. Sensory involvement may produce progressive numbness and pain. In extreme cases, sensory involvement can lead to diabetic ulcers and amputation.

What are the risks to others?

Diabetic neuropathy is not contagious, and poses no risk to others.
