Skin Signs Of Diabetes

Too much insulin in the body can lead to dark patches on the back of your neck, armpits and genital areas. This is usually a sign of prediabetes, which is medically known as acanthosis nigricans.
2. Recurrent boils

3. Hard, thickening skin
Medically known as digital sclerosis, hard and thickening skin usually develops on the fingers, toes, or both. It may start on the back of your hands, and progress to the forearms and upper arms due to uncontrolled diabetes. In some cases, it can spread to the chest, shoulders and face.
4. Skin tags
Have you been noticing small growths which are of the same colour as your skin? A lot of people with high levels of blood sugar or type-2 diabetes tend to have skin tags. They are non-cancerous growths that look like a cluster of skin tissue hanging from a stalk. They are also known as acrochordons.
