2. Common Causes of Acanthosis Nigricans

There are several associated causes of acanthosis nigricans. Insulin resistance is the most common trigger, and the condition is regularly seen in conjunction with type 2 diabetes. In some cases, acanthosis nigricans occurs as a result of hormonal issues, such as ovarian cysts and thyroid conditions.

Those on niacin supplement , birth control pills and prednisone tablets are also more likely to develop acanthosis nigricans because these medications can cause elevated levels of insulin. The condition can also be caused by cancer, in rare cases.2Mayo Clinic. ‘Acanthosis nigricans - Symptoms and Causes.’ Mayo Clinic, 9 June 2020,
