Acanthosis nigricans is often caused by insulin resistance, which is a condition where the body's cells do not respond properly to insulin. This can lead to high levels of insulin in the blood, which can cause the skin to darken and thicken. Other causes of acanthosis nigricans include obesity, hormonal disorders, certain medications, and cancer.
The main symptom of acanthosis nigricans is the appearance of dark, thick, and velvety patches on the skin. These patches may be itchy or have a bad odor. Acanthosis nigricans can also cause the skin to become thick and leathery, and it may feel like there is a lump or bump under the skin.
The best way to treat acanthosis nigricans is to address the underlying health problem that is causing it. If acanthosis nigricans is caused by insulin resistance, then lifestyle changes such as losing weight, eating a healthy diet, and exercising regularly can help to improve insulin sensitivity. In some cases, medications such as metformin may be prescribed to help lower blood sugar levels.
It is also important to keep the affected areas of skin clean and dry. Mild soaps and moisturizers can help to keep the skin soft and prevent itching. In severe cases, creams or lotions containing keratolytic agents such as salicylic acid or urea may be prescribed to help reduce the thickness of the skin.
The best way to prevent acanthosis nigricans is to maintain a healthy weight, eat a balanced diet, and exercise regularly. It is also important to manage any underlying health conditions such as diabetes or hypothyroidism.
If you notice any dark, thick, or velvety patches on your skin, it is important to see a dermatologist for an evaluation. While acanthosis nigricans is usually harmless, it can be a sign of an underlying health problem that needs to be addressed.
