Preventing Diabetic Foot
Too much glucose in the blood for a long time can cause diabetes problems. You can do a lot to prevent or slow down diabetes problems.
High blood glucose from diabetes causes two problems that can hurt your feet:
One problem is damage to nerves in your legs and feet. With damaged nerves, you might not feel pain, heat, or cold in your legs and feet. A sore or cut on your foot may get worse because you do not know it is there. This lack of feeling is caused by nerve damage, also called diabetic neuropathy. Nerve damage can lead to a sore or an infection.
Poor blood flow
The second problem happens when not enough blood flows to your legs and feet. Poor blood flow makes it hard for a sore or infection to heal. This problem is called peripheral vascular disease, also called PVD. Smoking when you have diabetes makes blood flow problems much worse.
For example, you get a blister from shoes that do not fit. You do not feel the pain from the blister because you have nerve damage in your foot. Next, the blister gets infected. If blood glucose is high, the extra glucose feeds the germs. Germs grow and the infection gets worse. Poor blood flow to your legs and feet can slow down healing. Once in a while a bad infection never heals. The infection might cause gangrene. If a person has gangrene, the skin and tissue around the sore die. The area becomes black and smelly.
The National Diabetes Information Clearinghouse (NDIC) recommends following steps to care of your feet if you are diabetic:
- Wash your feet in warm water every day - Make sure the water is not too hot by testing the temperature with your elbow. Do not soak your feet. Dry your feet well, especially between your toes.
- Look at your feet every day to check for cuts, sores, blisters, redness, calluses, or other problems - Checking every day is even more important if you have nerve damage or poor blood flow. If you cannot bend over or pull your feet up to check them, use a mirror. If you cannot see well, ask someone else to check your feet.
- If your skin is dry, rub lotion on your feet after you wash and dry them. Do not put lotion between your toes.
- File corns and calluses gently with an emery board or pumice stone. Do this after your bath or shower.
- Cut your toenails once a week or when needed. Cut toenails when they are soft from washing. Cut them to the shape of the toe and not too short. File the edges with an emery board.
- Always wear slippers or shoes to protect your feet from injuries
- Always wear socks or stockings to avoid blisters. Do not wear socks or knee-high stockings that are too tight below your knee.
- Wear shoes that fit well. Shop for shoes at the end of the day when your feet are bigger. Break in shoes slowly. Wear them 1 to 2 hours each day for the first few weeks.
- Before putting your shoes on, feel the insides to make sure they have no sharp edges or objects that might injure your feet.
- Tell your doctor right away about any foot problems.
- Your doctor should do a complete foot exam every year.
- Ask your doctor to look at your feet at each diabetes check-up. To make sure your doctor checks your feet, take off your shoes and socks before your doctor comes into the room.
- Ask your doctor to check how well the nerves in your feet sense feeling.
- Ask your doctor to check how well blood is flowing to your legs and feet.
- Ask your doctor to show you the best way to trim your toenails. Ask what lotion or cream to use on your legs and feet.
- If you cannot cut your toenails or you have a foot problem, ask your doctor to send you to a foot doctor. A doctor who cares for feet is called a podiatrist.
• The subsequent foot care management plan depends on risk category, foot status, and metabolic control.
• High risk patients should be referred to a health care provider with training in foot care.
