Disease, years of wear and tear, ill-fitting or poorly designed shoes, poor circulation to the feet, or improperly trimmed toenails cause many common foot problems.
To prevent foot problems, check your feet regularly -- or, have them checked by a member of the family -- and practice good foot hygiene. Podiatrists and primary care physicians (internists and family practitioners) are qualified to treat most feet problems; sometimes the special skills of an orthopedic surgeon or dermatologist are needed.
In every issue of WebMD the Magazine, we ask our experts to answer readers' questions about a wide range of topics. In our January-February 2011 issue, we asked WebMD's diabetes expert, Michael Dansinger, MD, to answer a question about the link between prediabetes and diabetes.
Q: At my last checkup, my doctor told me I have prediabetes. Does that mean I'll ultimately develop diabetes?
A: Almost everyone who develops type 2 diabetes develops prediabetes first. But not everyone who has prediabetes...
Improving the circulation of blood to the feet can help prevent problems. Exposure to cold temperatures or water, pressure from shoes, long periods of sitting, or smoking can reduce blood flow to the feet. Even sitting with your legs crossed or wearing tight, elastic garters or socks can affect circulation. On the other hand, raising the feet, standing up and stretching, walking, and other forms of exercise promote good circulation. Gentle massage and warm foot baths can also help increase circulation to the feet.
Wearing comfortable shoes that fit well can prevent many foot ailments. Foot width may increase with age. Always have your feet measured before buying shoes. The upper part of the shoes should be made of a soft, flexible material to match the shape of your foot. Shoes made of leather can reduce the possibility of skin irritations. Soles should provide solid footing and not be slippery. Thick soles lessen pressure when walking on hard surfaces. Low-heeled shoes are more comfortable, safer, and less damaging than high-heeled shoes.
Common Foot Problems
Fungal and bacterial conditions -- including athlete's foot -- occur because the feet are usually enclosed in a dark, damp, warm environment. These infections cause redness, blisters, peeling, and itching. If not treated promptly, an infection may become chronic and difficult to cure. To prevent these conditions, keep the feet -- especially the area between the toes -- clean and dry and expose the feet to air whenever possible. If you are prone to fungal infections, you may want to dust your feet daily with a fungicidal powder.
Dry skin can cause itching and burning feet. Use mild soap sparingly and a body lotion on your legs and feet every day. The best moisturizers contain petroleum jelly or lanolin. Be cautious about adding oils to bath water since they can make the feet and bathtub very slippery.
