Diabetes - taking care of your feet
Diabetes - foot care - self-care; Diabetic foot ulcer - foot care; Diabetic neuropathy - foot careDiabetes can damage the nerves and blood vessels in your feet. This damage can cause numbness and reduce feeling in your feet. As a result, your feet are more likely to become injured and may not heal well if they are injured. If you get a blister, you may not notice and it may get worse. Even small sores or blisters can become big problems if infection develops or they don't heal. A diabetic foot ulcer can result. Foot ulcers are a common reason for hospital stays for people with diabetes. Taking good care of your feet can help prevent diabetic foot ulcers. Untreated foot ulcers are the most common reason for toe, foot, and leg amputations in people with diabetes.
Diabetes
Diabetes is a long-term (chronic) disease in which the body cannot regulate the amount of sugar in the blood.
Diabetic foot ulcer
If you have diabetes, you have an increased chance of developing foot sores, or ulcers, also called diabetic ulcers. Foot ulcers are a common reason ...
Self-care
Follow your health care provider's instructions on how to take care of your feet. Use the information below as a reminder.
Diabetes is a long-term (chronic) disease in which the body cannot regulate the amount of sugar in the blood.
Check your feet every day. Inspect the tops, sides, soles, heels, and between your toes. Look for:
- Dry and cracked skin
- Blisters or sores
- Bruises or cuts
- Redness, warmth, or tenderness (often absent because of nerve damage)
- Firm or hard spots
If you cannot see well, ask someone else to check your feet.
Wash your feet every day with lukewarm water and mild soap. Strong soaps may damage the skin.
- Check the temperature of the water with your hand or elbow first.
- Gently dry your feet, especially between the toes.
- Use lotion, petroleum jelly, lanolin, or oil on dry skin. Do not put lotion, oil, or cream between your toes.
Ask your provider to show you how to trim your toenails.
- Soak your feet in lukewarm water to soften your toenails before trimming.
- Cut the nails straight across. Curved nails are more likely to become ingrown.
- Make sure the edge of each nail does not press into the skin of the next toe.
Do not try to cut very thick toenails by yourself. Your foot doctor (podiatrist) can trim your toenails if you are unable to. If your toenails are thick and discolored (possibly due to a fungal infection) do not trim the nails yourself. If your vision is poor or you have decreased sensation in your feet, you should see a podiatrist to trim your toenails to prevent possible injury.
Most people with diabetes should have corns or calluses treated by a foot doctor. If your doctor has given you permission to treat corns or calluses on your own:
- Gently use a pumice stone to remove corns and calluses after a shower or bath, when your skin is soft.
- Don't use medicated pads or try to shave or cut corns and calluses away at home.
If you smoke, stop. Smoking decreases blood flow to your feet. Talk to your provider or nurse if you need help quitting.
Do not use a heating pad or hot water bottle on your feet. Don't walk barefoot, particularly on hot pavement, hot tiles, or hot, sandy beaches. This can cause severe burns in people with diabetes because the skin does not respond normally to the heat.
Remove your shoes and socks during visits to your provider so that they can check your feet.
Shoes and Socks
Wear shoes at all times to protect your feet from injury. Before you put them on, always check the inside of your shoes for stones, nails, or rough areas that may hurt your feet.
Wear shoes that are comfortable and fit well when you buy them. Never buy shoes that are tight, not even if you think they will stretch as you wear them. You may not feel pressure from shoes that do not fit well. Blisters and sores can develop when your foot presses against your shoe.
Ask your provider about special shoes that can give your feet more room. When you get new shoes, break them in slowly. Wear them 1 or 2 hours a day for the first 1 or 2 weeks.
Change your broken-in shoes after 5 hours during the day to change the pressure points on your feet. Do not wear flip-flop sandals or stockings with seams. Both can cause pressure points.
To protect your feet, wear clean, dry socks or non-binding panty hose every day. Holes in socks or stockings can put damaging pressure on your toes.
You may want special socks with extra padding. Socks that move moisture away from your feet will keep your feet drier. In cold weather, wear warm socks, and do not stay out in the cold for very long. Wear clean, dry socks to bed if your feet are cold.
When to Call the Doctor
Call your provider right way about any foot problems you have. Do not try to treat these problems yourself. Call your provider if you have any of the following changes to any part of your foot:
- Redness, increased warmth, or swelling
- Sores or cracks
- Tingling or burning feeling
- Pain

Proper fitting shoe - illustration
Shoes should be comfortable and fit well when you buy them. Never buy shoes that are tight, hoping they will stretch as you wear them. Because of nerve damage, people with diabetes may not feel a shoe rubbing against the skin of their foot. Blisters and sores may then develop. This can be worse if toenails are long, thick, or jagged. In people with diabetes, feet may not heal well if they get injured because of poor blood flow. This can lead to a serious infection.

People with diabetes are prone to foot problems because the disease can cause damage to the blood vessels and nerves, which may result in decreased ability to sense a trauma to the foot. The immune system is also altered, so that the person with diabetes cannot efficiently fight infection.

Monofilament test - illustration
A monofilament test is done to test for nerve damage (peripheral neuropathy), which may be caused by conditions such as diabetes. The monofilament is a small strand of nylon attached to a plastic base. The provider uses this monofilament to check for loss of feeling on your foot.
