Gonadotropin-releasing hormone agonists can relieve pain from endometriosis by stopping production
of the hormones that make endometriosis worse. This treatment may also
relieve pelvic pain that comes in cycles but isn't related to endometriosis and pelvic pain
irritable bowel syndrome. This short-term treatment brings on
menopause, though, with side effects such as
hot flashes and loss of bone density, for as long as
you take it.
