Obesity and Skin Problems: Acanthosis Nigricans


Acanthosis nigricans (ak-an-THOE-sis NIE-grih-kuns) is a skin condition characterized by dark, thick, velvety skin in body folds and creases. Most often, acanthosis nigricans affects your armpits, groin and neck. With acanthosis nigricans, you may naturally be concerned about the appearance of your skin. Some steps may help lighten the affected areas of your skin. There's no specific treatment for acanthosis nigricans (video here) — but treating any underlying conditions, such as diabetes and obesity, may cause the changes in your skin to fade.

SYMPTOMS, characteristics of acanthosis nigricans include:

  • Skin changes. Skin changes are the only signs of acanthosis nigricans. You'll notice dark, thick, velvety skin in body folds and creases — typically in your armpits, groin and neck. Sometimes the lips, palms or soles of the feet are affected as well.
  • Slow progression. The skin changes appear slowly, sometimes over months or years.
  • Possible itching. Rarely, the affected areas may itch.

When to see a doctor?

Consult your doctor if you notice changes in your skin — especially if the changes appear suddenly. You may have an underlying condition that needs treatment.


CAUSES

Acanthosis nigricans is often associated with conditions that increase your insulin level, such as type 2 diabetes or being overweight. If your insulin level is too high, the extra insulin may trigger activity in your skin cells. This may cause the characteristic skin changes.

In some cases, acanthosis nigricans is inherited. Certain medications — such as oral contraceptives and large doses of niacin — can contribute to the condition. Other hormone problems, endocrine disorders or tumors may play a role as well. Rarely, acanthosis nigricans is associated with certain types of cancer.
