Why Is Good Foot Care Important for People with Diabetic Neuropathy?

People with diabetes need to take special care of their feet. Neuropathy and blood vessel disease both increase the risk of foot ulcers. The nerves to the feet are the longest in the body, and are most often affected by neuropathy. Because of the loss of sensation caused by neuropathy, sores or injuries to the feet may not be noticed and may become ulcerated.

At least 15 percent of all people with diabetes eventually have a foot ulcer, and 6 out of every 1,000 people with diabetes have an amputation. However, doctors estimate that nearly three quarters of all amputations caused by neuropathy and poor circulation could be prevented with careful foot care.

To prevent foot problems from developing, people with diabetes should follow these rules for foot care:

  • Check your feet and toes daily for any cuts, sores, bruises, bumps, or infections--using a mirror if necessary.
  • Wash your feet daily, using warm (not hot) water and a mild soap. If you have neuropathy, you should test the water temperature with your wrist before putting your feet in the water. Doctors do not advise soaking your feet for long periods, since you may lose protective calluses. Dry your feet carefully with a soft towel, especially between the toes.
  • Cover your feet (except for the skin between the toes) with petroleum jelly, a lotion containing lanolin, or cold cream before putting on shoes and socks. In people with diabetes, the feet tend to sweat less than normal. Using a moisturizer helps prevent dry, cracked skin.
  • Wear thick, soft socks and avoid wearing slippery stockings, mended stockings, or stockings with seams.
  • Wear shoes that fit your feet well and allow your toes to move. Break in new shoes gradually, wearing them for only an hour at a time at first. After years of neuropathy, as reflexes are lost, the feet are likely to become wider and flatter. If you have difficulty finding shoes that fit, ask your doctor to refer you to a specialist, called a pedorthist, who can provide you with corrective shoes or inserts.
  • Examine your shoes before putting them on to make sure they have no tears, sharp edges, or objects in them that might injure your feet.
  • Never go barefoot, especially on the beach, hot sand, or rocks.
  • Cut your toenails straight across, but be careful not to leave any sharp corners that could cut the next toe.
  • Use an emery board or pumice stone to file away dead skin, but do not remove calluses, which act as protective padding. Do not try to cut off any growths yourself, and avoid using harsh chemicals such as wart remover on your feet.
  • Test the water temperature with your elbow before stepping in a bath.
  • If your feet are cold at night wear socks. (Do not use heating pads or hot water bottles.)
  • Avoid sitting with your legs crossed. Crossing your legs can reduce the flow of blood to the feet.
  • Ask your doctor to check your feet at every visit, and call your doctor if you notice that a sore is not healing well.
  • If you are not able to take care of your own feet, ask your doctor to recommend a podiatrist (specialist in the care and treatment of feet) who can help.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
