Neuropathy and blood vessel disease both increase the risk of foot ulcers. The nerves of the feet are the longest in the body and often are affected by neuropathy. When a diabetes patient loses sensation in the feet, sores or injuries may go unnoticed until ulcers develop.

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), at least 15 percent of all people with diabetes eventually develop a foot ulcer, and six out of every 1,000 people with diabetes require an amputation. Nearly three quarters of all amputations caused by neuropathy and poor circulation could be prevented with careful foot care.

To prevent foot problems from developing, the NIDDK recommends that people with diabetes take care of the disease and its symptoms, and follow these suggestions for proper foot care:

- Never go barefoot, especially on the beach, hot sand, or rocks
- Wear socks if your feet become cold at night. Do not use heating pads or hot water bottles
- Wash your feet daily, using warm (not hot) water and a mild soap
- Wear shoes that fit your feet well and allow your toes to move.
