Diabetes may cause nerve damage that takes away the feeling in your feet. Diabetes may also reduce blood flow to the feet, making it harder to heal an injury or resist infection. To avoid serious foot problems that could result in losing a toe, foot, or leg, be sure to follow these guidelines.
- Inspect your feet daily. Check for cuts, blisters, redness, swelling, or nail problems. Use a magnifying hand mirror to look at the bottom of your feet. Call your doctor if you notice anything.
- Wash your feet in lukewarm (not hot!) water. Keep your feet clean by washing them daily. But only use lukewarm water — the temperature you’d use on a newborn baby.
- Be gentle when bathing your feet. Wash them using a soft washcloth or sponge. Dry by blotting or patting and make sure to carefully dry between the toes.
- Moisturize your feet — but not between your toes. Use a moisturizer daily to keep dry skin from itching or cracking. Don't moisturize between the toes — this could encourage a fungal infection.
- Cut nails carefully and straight across. Also, file the edges. Don’t cut them too short, since this could lead to ingrown toenails.
- Never trim corns or calluses. No “bathroom surgery” — let your doctor do the job.
- Wear clean, dry socks. Change them daily.
- Avoid the wrong type of socks. Avoid tight elastic bands (they reduce circulation). Don’t wear thick or bulky socks (they can fit poorly and irritate the skin).
- Wear socks to bed. If your feet get cold at night, wear socks. Never use a heating pad or hot water bottle.
- Shake out your shoes and inspect the inside before wearing them. Remember, you may not feel a pebble — so always shake out your shoes before putting them on.
- Keep your feet warm and dry. Don’t get your feet wet in snow or rain. Wear warm socks and shoes in winter.
- Never walk barefoot. Not even at home! You could step on something and get a scratch or cut.
- Take care of your diabetes. Keep your blood sugar levels under control.
- Don’t smoke. Smoking restricts blood flow in your feet.
- Get periodic foot exams. See your podiatric foot and ankle surgeon on a regular basis for an examination to help prevent the foot complications of diabetes.
Foot Problems in Persons with Diabetes
Foot problems in persons with diabetes are usually the result of three primary factors: neuropathy, poor circulation, and decreased resistance to infection.
- Neuropathy (Nerve Damage): Neuropathy allows injuries to remain unnoticed and untreated. It may cause burning, sharp pains in feet, a loss of sensation, and affect the nerves that supply the muscles in your feet and legs.
- Poor Circulation: Persons with diabetes often have circulation disorders with symptoms progressing to severe cramping, pain, color, and temperature changes. Poor circulation restricts the delivery of oxygen and nutrients that are required for normal maintenance and repair.
- Infection: Due to deficiencies in the ability of white blood cells to defend against invading bacteria, diabetics have more difficulty in dealing with and mounting an immune response to the infection. A key sign of a developing infection is unexplained high blood sugar, even with or without fever. Fever and high blood sugar often warn of a severe infection.
- Foot Deformities: Deformities include hammertoes, bunions, and metatarsal disorders, all of which, places the foot at increased risk for developing corns, calluses, blisters, and ulcerations.
