Acanthosis nigricans is a skin condition characterized by thickening and darkening of the skin, particularly in areas such as the neck, armpits, groin, and skin folds. The affected skin may also feel velvety or rough to the touch.
Acanthosis nigricans is typically associated with insulin resistance, which is a common feature of type 2 diabetes. It can also be caused by certain medications, hormonal imbalances, and, in rare cases, cancer.
In addition to skin changes, individuals with acanthosis nigricans may also have other signs of insulin resistance, such as obesity, high blood pressure, and abnormal cholesterol levels.
Diagnosis of acanthosis nigricans typically involves a physical examination and blood tests to evaluate for underlying medical conditions. Treatment of acanthosis nigricans depends on the underlying cause. In cases where the condition is associated with insulin resistance or type 2 diabetes, treatment may involve lifestyle changes such as weight loss, regular exercise, and dietary modifications, as well as medications to improve blood sugar control.
If you notice any changes in your skin, particularly if they are accompanied by other symptoms such as weight gain or abnormal blood sugar levels, it is important to see a healthcare provider for evaluation and diagnosis.
