Excessive or unwanted hair in women

• Overview
• Treatment

Definition:

The normal amount of body hair varies widely among women. When coarse, dark hairs grow where women typically do not grow dark hair, such as the lip, chin, chest, abdomen, or back, the condition is called hirsutism.

Alternative Names:

Hypertrichosis; Hirsutism; Hair - excessive (women)

Common Causes:

Excessive hair growth in women is usually from too much male hormone (androgen). A common cause is polycystic ovarian syndrome (PCOS). In most cases, however, the specific cause is never identified. It tends to run in families. In general, hirsutism is a harmless condition. But many women find it bothersome, even embarrassing.

If hirsutism develops suddenly and is accompanied by other typical male features, such as deepening voice, acne, or increased muscle mass, it may be caused by a more serious disorder. These causes, such as hormone-secreting tumors or cancer, are rare.

Rare causes include:

• Tumor or cancer of the adrenal gland.
• Tumor or cancer of the ovary
• Cushing's syndrome
• Congenital adrenal hyperplasia
• Hyperthecosis
• Medications (testosterone, danazol, anabolic steroids, glucocorticoids, cyclosporine, minoxidil, phenytoin)
