Genetics

Acanthosis nigricans can be inherited, and is more common in people of African, Hispanic, and Native American descent. It is also more common in people with certain genetic disorders, such as Down syndrome, Turner syndrome, and Prader-Willi syndrome.

Obesity

Obesity is a major risk factor for acanthosis nigricans. The condition is more common in people who are overweight or obese, and is often seen in children who are overweight. It is thought that the excess fat in the body may cause the skin to produce more of the pigment melanin, which can lead to the dark patches.

Hormones

Hormonal imbalances can also be a cause of acanthosis nigricans. The condition is more common in people with certain endocrine disorders, such as Cushing's syndrome, polycystic ovary syndrome, and hypothyroidism. It is also seen in pregnant women, due to the increased levels of hormones in the body.

Medications

Certain medications can also cause acanthosis nigricans. These include oral contraceptives, growth hormones, and insulin. If you are taking any of these medications and develop acanthosis nigricans, it is important to talk to your doctor about changing your medication.

Diagnostic Tests

A physical examination of the affected area is usually the first step in diagnosing acanthosis nigricans. The doctor may also take a biopsy of the skin to confirm the diagnosis. Blood tests may also be done to check for underlying medical conditions that may be causing the condition.

Treatment

Treatment for acanthosis nigricans typically involves treating any underlying medical conditions that may be causing the condition. This may include medications, lifestyle changes, or surgery. Topical creams and ointments may also be used to reduce the appearance of the patches.
