Your skin, the largest organ in your body, often reflects internal health issues, including diabetes. While diabetes is primarily known for its impact on blood sugar levels, it can also manifest through various skin conditions. Recognizing these signs can help in early diagnosis and management. Here’s a closer look at thirteen skin signs linked to diabetes, their causes, and what you should do if you notice them.
Necrobiosis LipoidicaThis rare inflammatory condition starts as small red, raised patches, usually on the shins, but it can appear on other parts of the body.
The patches may grow larger, forming irregular shapes with red borders and a yellowish center. Although the exact cause is unknown, it's commonly seen in people with diabetes and may be related to damage to collagen fibers in the skin.

Acanthosis NigricansCharacterized by dark, velvety patches typically found in skin folds such as the neck, armpits, and groin, acanthosis nigricans is linked to insulin resistance, a key factor in diabetes development.
It’s also seen in conditions like obesity, polycystic ovary syndrome, and Cushing syndrome.
Granuloma AnnulareThis condition presents as tiny, red bumps around the ankles, hands, and arms.
