If a doctor has ever said you had an elevated blood sugar level Ė even just once when you were pregnant Ė you are at risk for diabetes. About 15.7 million people (5.9 percent of the United States population) have the disease. Nervous system impairment (neuropathy) is a major complication that may cause you to lose feeling in your feet or hands. This means you wonít know right away if you hurt yourself. The problem affects about 60 to 70 percent of people with diabetes.
Foot problems are a big risk. Like all diabetic people, you should monitor your feet. If you donít, the consequences can be severe, including amputation, or worse.
Minor injuries become major emergencies before you know it. With a diabetic foot, a wound as small as a blister from wearing a shoe thatís too tight can cause a lot of damage. Diabetes decreases your blood flow, so your injuries are slow to heal. When your wound is not healing, itís at risk for infection. As a diabetic, your infections spread quickly.
If you have diabetes, you should inspect your feet every day. Look for puncture wounds, bruises, pressure areas, redness, warmth, blisters, ulcers, scratches, cuts and nail problems. Get someone to help you, or use a mirror. Feel each foot for swelling. Examine between your toes. Check six major locations on the bottom of each foot: The tip of the big toe, base of the little toes, base of the middle toes, heel, outside edge of the foot and across the ball of the foot. Check for sensation in each foot.
If you find any injury -- no matter how slight -- donít try to treat it yourself. Go to a doctor right away.
Hereís some basic advice for taking care of your feet:

When your feet lose their feeling, they are at risk for becoming deformed. One way this happens is through ulcers. Open sores may become infected. Another way is the bone condition Charcot (pronounced "sharko") foot. This is one of the most serious foot problems you can face. It warps the shape of your foot when your bones fracture and disintegrate, and yet you continue to walk on it because it doesn't hurt.
A doctor may treat your diabetic foot ulcers and early phases of Charcot fractures with a total contact cast. The shape of your foot molds the cast. It lets your ulcer heal by distributing weight and relieving pressure. If you have Charcot foot, the cast controls your footís movement and supports its contours if you donít put any weight on it. To use a total contact cast, you need good blood flow in your foot. Your doctor monitors it carefully. The cast is changed every week or two until your foot heals.
A custom-walking boot is an another way to treat your Charcot foot. It supports the foot until all the swelling goes down, which can take as long as a year. You should keep from putting your weight on the Charcot foot. Surgery is considered if your deformity is too severe for a brace or shoe.
