Diabetic rashes can be treated with medications depending on the type of rash, the American Diabetes Association advises. For instance, diabetics can get rashes through fungal infections, yeast infections, bacterial infection or allergic reactions.
Diabetics often get rashes caused by fungal or yeast infections, states the American Diabetes Association. The fungus most often at fault, Candida albicans, grows in moist, warm areas such as the groin, under the armpits, between the toes and fingers and under the breasts. Diabetics can also get ringworm, athlete's foot and jock itch. These infections can be treated with over-the-counter medications and topical creams, explains WebMD. Recurring infections require boric acid medication or anti-fungal drugs. Taking probiotics can help to prevent further problems.
Occasionally rashes occur due to allergic reactions to insulin or other diabetic medications, the American Diabetes Association states. Often these rashes form at the site where the diabetic injects insulin. He should see his physician immediately for treatment.
Another cause of rashes in diabetics is a skin condition called disseminated granuloma annulare, says the American Diabetes Association. These raised ring-shaped rashes are usually red or brown. Usually these rashes resolve on their own, Mayo Clinic says. However, medications can help it to disappear.
