How Does Peripheral Neuropathy Affect Feet?

5. Diabetic Foot Ulcers

Diabetic foot ulcers are among the most common complications of peripheral neuropathy in the feet. In addition to nerve damage, long-term high blood sugar can cause poor circulation that interferes with healing. Small wounds or sores on the feet may heal very slowly or become infected.

In severe cases, the infection can spread to the bone and some people require amputation. People with diabetes should regularly examine their feet and seek prompt medical attention for any wounds, even minor scrapes or cuts.
