High blood sugars can lead to various skin problems. Some common skin problems are:
Acanthosis Nigricans: This condition causes dark patches of thickened, “velvety” skin to develop in areas where there are skin folds, such as the neck, groin, and underarms. The most frequent trigger of this problem is obesity and too much insulin in your bloodstream because the body is resisting insulin.
Localized Itching: People with diabetes often experience itchy and cracked skin, particularly in the lower legs, which can be caused by dryness, poor circulation, or infections.
Diabetic Dermopathy (DD): It is characterized by light brown scaly patches on the shins and legs, it is the most common skin condition associated with diabetes.
Bacterial and Fungal Infections: People with diabetes are often more prone to bacterial and fungal infections of the skin, including staphylococcus (staph) infections, yeast infections, and athlete’s foot.
Necrobiosis: A skin condition seen almost exclusively in people with diabetes or people who are insulin resistant, necrobiosis appears as a rash of purple spots, most often on the lower legs and feet.
Digital Sclerosis: This skin condition is marked by thickened, “waxy” skin, usually on the back of the hands, fingers, toes or back. The skin, particularly on the legs, can become thin and hairless, and prone to developing ulcers. The reduced blood flow can slow wound healing, allowing infections to develop.
