Why Won't This Cut Heal

Slow-healing wounds are one of the more troubling potential signs of diabetes. It may take a long time for even a simple cut or scrape to get better in someone with diabetes. Why? "The blood supply isn't as good," and "the immune cells which help heal wounds do not function properly," says Dr. Nikheel Kolatkar, an endocrinologist at the University of Pennsylvania/Philadelphia VA Medical Center. If not resolved, diabetic wounds can become very dangerous.

Diabetes can also cause numbness, tingling or pain in the legs, feet or hands, which may indicate nerve damage. "Symptoms of nerve damage are quite common and can even be the first symptoms of diabetes" says Dr. Kolatkar.

Other ways diabetes can get under your skin:
•Dark, velvety patches in the skin folds
•Frequent or persistent infections, including gum disease
