Can hirsutism be dangerous?

Hirsuitism: Most times just annoying or embarrasing but occasionally it indicates an underlying ovarian or adrenal problem.

Very rarely: The #1 cause of excess hair growth in women is polycystic ovarian syndrome (pcos) which affects 8-10%. We diagnose pcos with an ultrasound scan & blood tests, looking for adrenal gland problems or other causes. Hormone-producing tumors causing hirsutism are incredibly rare. Pcos can pose some long-term risks if untreated like a higher chance of diabetes; rarely uterine cancer if few periods a year.

Depends on the cause: If the hirsutism is caused by an adrenal mass, then it's more dangerous. If it's caused by polycystic ovarian syndrome, then it will impact your life but not necessarily kill you. The most important thing is to find out the cause of the hirsutism.
