Dark Skin Patches May Indicate Insulin Resistance and Early Diabetes Risk

Acanthosis nigricans, characterized by dark, velvety patches on skin folds such as the neck, underarms, and groin, may signal insulin resistance and early diabetes risk. Often mistaken for dirt or pigmentation, these skin changes reflect underlying metabolic issues. Common in adolescents and young adults, especially in regions with high diabetes rates, the condition indicates the body's struggle to regulate blood sugar. Medical evaluation and lifestyle changes are recommended for early detection and prevention.
