Diabetics develop rashes and itchy skin due to bacterial or fungal infections, allergic reactions, poor circulation and diseases directly related to diabetes, says the American Diabetes Association. Diabetics develop poor circulation due to high blood sugar levels. This manifests in itchy skin, particularly on the legs and feet. Diabetic dermopathy, necrobiosis lipoidica diabeticorum and eruptive xanthomatosis are all diseases that diabetics can develop because of blood vessel damage. Dermopathy produces scaly, itchy patches. Diabeticorum produces shiny scar tissues that are itchy. Xanthomatosis produces itchy bumps.
Diabetics are also prone to getting infected by the Candida albicans fungus, says the American Diabetes Association. This fungus causes itchy rashes and blisters. This is especially common in the moist areas of the skin where the fungus can grow easily such as in skin folds, in the armpits and between fingers and toes. Another diabetes-related skin condition that results in rashes is disseminated granuloma annulare. Diabetics with this condition develop raised rashes on the extremities.Learn more about Conditions & Diseases
