Diabetes and Your Skin
Much like the effect it has on your feet and eyes, diabetes also directly affects your skin. When blood sugar is high, the body is losing water. When the body loses water, the skin becomes dry and itchy. The skin can also become sore from the constant scratching and flaking, resulting in patchy areas that allow germs to enter the body. Also, cracked skin is a result of dryness. Cracks can also allow germs to enter the body, and, because your sugar level is high, these areas can become breeding grounds for infection. Also, if nerve damage has occurred, your body may not be able to sweat properly, a mechanism it uses for keeping the skin soft and moist. Without sweat, the body may develop dry patches. Areas such as heels, elbows, and knees are especially prone to dryness.
