- Clean your feet daily. Dry them thoroughly, especially between the toes, before putting shoes and socks on.
- Do not wear garters and tight stockings around the legs.
- You may want to use petroleum jelly or an unscented lotion to moisturize dry, leathery feet. Do not put lotion between the toes. The extra moisture may attract bacteria.
- Inspect your feet daily. Look for sores that you may not be able to feel. Use a mirror or the assistance of another person to see all parts of your feet.
- Your doctor should look at your feet and test the feeling in them at least once a year. If you find a sore at any time, make an appointment to see your doctor right away.
- People with diabetes may have toenails that are brittle and difficult to cut. You may also want to have a foot specialist trim your toenails regularly.
- Buy properly fitted shoes. Some insurance companies will pay for custom-made shoes with inserts. A doctor can give you a prescription for the shoes.
- Avoid smoking.
- Talk to your doctor about exercise. Daily exercise will help to improve blood flow and blood sugar levels.
- Calluses can increase the pressure on the foot and lead to foot ulcers. Have your foot doctor remove any calluses. This could reduce the risk of developing a foot ulcer.
- Ask your doctor if you should use a special infrared thermometer. It can check the temperature of your feet.
- Improved control of your diabetes may reduce the risk of ulcers
