Neuropathy and blood vessel disease both raise the risk for foot sores called ulcers. The nerves of the feet are the longest in the body. They often are affected by nerve injury (neuropathy). When a person with diabetes loses sensation in the feet, they may not notice sores or injuries until serious ulcers develop.
Preventing diabetic foot problems
To help keep foot problems from developing, the National Institute of Diabetes and Digestive and Kidney Diseases recommends that people with diabetes take care of the disease and its symptoms. They suggest the following proper foot care:
- Check your feet and toes daily for any cuts, sores, bruises, bumps or infections. Use a mirror to look at the bottom of your feet, or ask someone to help you.
- Wash your feet daily with warn water and mild soap. If you have neuropathy, test the water temperature with a thermometer or your wrist or elbow before putting your feet in the water. We don’t advise soaking your feet for long periods. Dry your feet carefully with a soft towel, especially between the toes.
- Except for the skin between the toes, cover your feet with petroleum jelly, a lotion containing lanolin or cold cream before putting on shoes and socks. For people with diabetes, the feet tend to sweat less than normal. Using a moisturizer helps prevent dry, cracked skin. Put talcum powder or cornstarch between your toes to keep those areas dry.
- Cut your toenails straight across, but be careful not to leave any sharp corners that could cut the next toe.
- Wear thick, soft socks. Don’t wear slippery stockings, mended stockings or stockings with seams.
- Check your shoes before putting them on to make sure they have no tears, sharp edges or objects in them that might harm your feet.
- Wear shoes that fit your feet well and let your toes move. Break in new shoes gradually. Wear them for only an hour at a time at first. After years of neuropathy, as reflexes are lost, the feet are likely to become wider and flatter.
- Use an emery board or pumice stone to file away dead skin, but don’t remove calluses using sharp tools. Don’t try to cut off any growths yourself. Don’t use harsh chemical such as wart remover on your feet.
- Don’t sit with your legs crossed. Crossing your legs can reduce the flow of blood to the feet. Don’t smoke. Elevate your legs when you are sitting. Wiggle your toes several times a day to keep the body flowing.
- Wear socks if your feet become cold at night. Don’t use heating pads or hot water bottles.
- Never go barefoot, especially on the bench, hot sand or rocks.
- Ask your healthcare provider to check your feet at every visit. Call your healthcare provider if you notice that a sore is not healing well. Take your shoes and socks off while you are waiting for your appointment to start.
The American Diabetes Association recommends that if you have a cut or break in your skin, or develop an ingrown toenail, call or see your healthcare provider. The ADA also says to contact your healthcare provider if your foot or feet change color, shape or just feel funny. This might be pain or loss of feeling.
