Causes of Diabetic Itching

According to the American Diabetes Association, approximately 1/3 of all diabetics will contract a diabetes-related skin complication at some point in their lives. In fact, it is not unusual for a patient to be treated for a diabetes-related skin disorder even before his diabetes is diagnosed. Some of these skin disorders can cause an irritating itch or rash, in which case you should contact your doctor for an appropriate treatment.

Localized Itching

If your skin is just itchy for no apparent reason, i.e. there is no rash or discoloration, it may be caused by a yeast infection, poor blood circulation (typically in the legs) or just dry skin.

Fungal Infection

A yeast-like fungus called canidida albicans can cause a variety of fungal infections like jock itch, ringworm and athlete's foot in diabetics. Candida albicans presents as a red, itchy rash with blisters and scales.

Eruptive Xanthomatosis

Eruptive xanthomatosis presents as hard, yellow, pea-sized bumps with red halos that typically appear on the hands, feet, arms, legs and buttocks. This condition is indicative of unbalanced blood glucose levels or high levels of lipids.

Necrobiosis Lipoidica Diabeticorum (NLD)

NLD is a rare condition caused by changes in your blood vessels. It begins as a dull, raised, red area and progresses into a shiny, scar-like spot with a violet border. It can become itchy, painful and may crack open.

Allergic Reactions

It is possible for you to have an allergic reaction to one of your diabetes medications. The allergy may present as a rash, a depression or bumps, especially around injection sites.
