Necrobiosis lipoidica often begins with small, firm bumps that gradually grow into larger, thickened patches—most commonly on the legs. These areas may appear red, yellow, or brown and develop a smooth, shiny surface that makes underlying blood vessels more visible.
The affected skin may itch, become inflamed, or alternate between flare-ups and quiet periods. While not everyone with diabetes will develop this condition, it occurs more frequently in people with the disease. Paying close attention to these skin changes can support early diagnosis and better management.
Acanthosis Nigricans
Acanthosis nigricans is a strong indicator that insulin is not functioning properly in the body. It presents as dark, velvety patches of skin, most often on the neck, underarms, or other skin folds.
This condition is commonly associated with insulin resistance and may appear before type 2 diabetes is diagnosed. Recognizing it early can prompt timely testing, lifestyle changes, or medical intervention—helping prevent blood sugar levels from becoming more difficult to control.
Digital Sclerosis
Digital sclerosis is another diabetes-related skin condition that causes the skin to harden and lose flexibility. This often affects the fingers and hands, leading to stiffness and limited movement that can interfere with everyday activities.
Managing blood sugar levels is essential for slowing its progression. Some individuals also find relief through physical therapy or supplements such as alpha-lipoic acid, which may help improve flexibility and comfort.
