Prevent diabetes problems: Keep your feet and skin healthy

What are diabetes problems?

Too much glucose in the blood for a long time can cause diabetes problems. This high blood glucose, also called blood sugar, can damage many parts of the body, such as the heart, blood vessels, eyes, and kidneys. Heart and blood vessel disease can lead to heart attacks and strokes. You can do a lot to prevent or slow down diabetes problems.

This information is about feet and skin problems caused by diabetes. You will learn the things you can do each day and during each year to stay healthy and prevent diabetes problems.

How can diabetes hurt my feet?

High blood glucose from diabetes causes two problems that can hurt your feet:

  • Nerve damage. 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.

These two problems can work together to cause a foot problem.

Diabetic Shoes, Washington DC
Make sure you wear
shoes that fit well.

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.

To keep gangrene from spreading, a doctor may have to do surgery to cut off a toe, foot, or part of a leg. Cutting off a body part is called an amputation.

What can I do to take care of my feet?

  • Feet Care, Washington DC
    Look at your feet every day to check for problems.
    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.
  • 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.

 

How can my doctor help me take care of my 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 checkup. 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.

What are common diabetes foot problems?

Anyone can have corns, blisters, and other foot problems. If you have diabetes and your blood glucose stays high, these foot problems can lead to infections.

Drawing of a foot with an arrow pointing to a blister. Blisters can form if shoes always rub the same spot. Wearing shoes that do not fit or wearing shoes without socks can cause blisters. Blisters can become infected.
Foot with an ingrown toenail. Ingrown toenails happen when an edge of the nail grows into the skin. The skin can get red and infected. Ingrown toenails can happen if you cut into the corners of your toenails when you trim them. You can also get an ingrown toenail if your shoes are too tight. If toenail edges are sharp, smooth them with an emery board.
Drawing of a foot with an arrow pointing to a bunion. A bunion forms when your big toe slants toward the small toes and the place between the bones near the base of your big toe grows big. This spot can get red, sore, and infected. Bunions can form on one or both feet. Pointed shoes may cause bunions. Bunions often run in the family. Surgery can remove bunions.
Drawing of the bottom of a foot with an arrow pointing to plantar warts. Plantar warts are caused by a virus. The warts usually form on the bottoms of the feet.
Drawing of a foot with an arrow pointing to a hammertoe. Hammertoes form when a foot muscle gets weak. Diabetic nerve damage may cause the weakness. The weakened muscle makes the tendons in the foot shorter and makes the toes curl under the feet. You may get sores on the bottoms of your feet and on the tops of your toes. The feet can change their shape. Hammertoes can cause problems with walking and finding shoes that fit well. Hammertoes can run in the family. Wearing shoes that are too short can also cause hammertoes.
Drawing of the bottom of a foot with an arrow pointing to dry and cracked skin. Dry and cracked skin can happen because the nerves in your legs and feet do not get the message to keep your skin soft and moist. Dry skin can become cracked. Cracks allow germs to enter and cause infection. If your blood glucose is high, it feeds the germs and makes the infection worse.
Drawing of the bottom of a foot with an arrow pointing to athlete‚Äôs foot. Athlete’s foot is a fungus that causes itchiness, redness, and cracking of the skin. The cracks between the toes allow germs to get under the skin and cause infection. If your blood glucose is high, it feeds the germs and makes the infection worse. The infection can spread to the toenails and make them thick, yellow, and hard to cut.

Tell your doctor about any foot problem as soon as you see it.

How can special shoes help my feet?

Special shoes can be made to fit softly around your sore feet or feet that have changed shape. These special shoes help protect your feet. Medicare and other health insurance programs may pay for special shoes. Talk with your doctor about how and where to get them.

How can diabetes hurt my skin?

Diabetes can hurt your skin in two ways:

  • If your blood glucose is high, your body loses fluid. With less fluid in your body, your skin can get dry. Dry skin can be itchy, causing you to scratch and make it sore. Also, dry skin can crack. Cracks allow germs to enter and cause infection. If your blood glucose is high, it feeds germs and makes infections worse. You may get dry skin on your legs, feet, elbows, and other places on your body.

    Drinking fluids helps keep your skin moist and healthy.
  • Nerve damage can decrease the amount you sweat. Sweating helps keep your skin soft and moist. Decreased sweating in your feet and legs can cause dry skin.

What can I do to take care of my skin?

  • After you wash with a mild soap, make sure you rinse and dry yourself well. Check places where water can hide, such as under the arms, under the breasts, between the legs, and between the toes.
