Acanthosis nigricans is often connected to obesity-related diabetes.
It’s those dark, velvety patches of skin appearing on the neck, throat, underarms, and in folds and creases, even in places where the sun doesn’t shine.
The Mayo Clinic says if your insulin level is too high, the extra insulin may trigger the characteristic changes in your skin cells. Sometimes certain medications, including oral contraceptives, can cause the condition. Hormone problems, endocrine disorders or tumors may play a role as well. Losing excess pounds if you’re overweight and cutting back on starches and sugars will help.
The bottom line is – if you have black velvety patches on your body, see your health care provider to determine the cause. When the underlying cause is treated, acanthosis nigricans improves or fades away.
