Diabetics who develop rashes should treat the underlying cause of the rash, such as using antifungal medications when fungal infections cause rash, notes Diabetic Lifestyle. Bacterial infection and itching from dry skin, yeast infection, allergic reaction or hindered blood flow all affect diabetics from time to time.
Diabetics tend to develop more bacterial infections than the overall population. Boils (infected hair follicles), sties (infected eyelid glands) and carbuncles (deep skin and tissue infections) all strike diabetics now and then. The affected tissue is hot to the touch and is also painful, red and swollen in many cases. Staphylococcus is the most frequent cause of these types of infections. The most common treatment is a course of antibiotics, either in a pill or cream, reports Diabetic Lifestyle.
Canidida albicans is a fungus that resembles yeast and is the cause for quite a few of fungal infections affecting diabetics. It leads to red sections and itchy rashes along with small blisters and scales. In the moist, warm folds on the skin, yeast infections such as athlete's foot, ringworm and jock itch can develop too. All require medical treatment, as stated by Diabetic Lifestyle.
Skin lotions are a popular treatment for leg itching, as they soften the skin on the leg and minimize this sort of itching. Some people have allergic responses to insulin or hyperglycemia pills, while others are allergic to some insect bites and foods. Having allergy medications on hand eases the discomfort associated with the itching, according to Diabetic Lifestyle.
