Diabetes rash is an early symptom of diabetes that can be noticed before a person is even diagnosed for diabetes. It is like a warning signal for diabetes. Skin rashes which occur in diabetes are also called as diabetic dermadromes.

Diabetes rash may occur due to the following reasons:
- Infection caused due to fungus
- Infection caused due to bacteria
- Reaction due to allergy
- Disseminated Granuloma Annulare
- Thickening of the arteries
- Necrobiosis lipoidica diabeticorum (NLD)
Most of the diabetes rash fungal infections are caused due to Candida albicans. It is yeast-like fungus that can be source for itchy rashes of moist, red areas surrounded by tiny blisters and scales.
Although many kinds of bacteria are responsible for diabetes rash, staphylococcus bacteria also called staph is the common one which is found in most of the patients suffering with this kind of rash.In some cases, insulin taken in injection form or pills may become allergic to the skin. This kind of allergic reaction will reflect in the form of rash or bumps.
Another peculiar type of rash which appears in ring form on the skin is caused by Disseminated Granuloma Annulare. Besides being formed in other parts of the body, ears and fingers are commonly affected areas.
Thickening of the arteries may lead to rash on the legs. This can be referred as diabetes leg rash. The affected skin changes the color, appears shining due to narrowed blood vessels.
Necrobiosis lipoidica diabeticorum (NLD) relates to the changes in the blood vessels.
