Clinical Information

Information for Patients


Uterine Diseases

The uterus, or womb, is the place where a baby grows when a woman is pregnant. The first sign of a problem with the uterus may be bleeding between periods or after sex. Causes can include hormones, thyroid problems, fibroids, polyps, cancer, infection, or pregnancy.

Treatment depends on the cause. Sometimes birth control pills treat hormonal imbalances. If a thyroid problem is the cause, treating it may also stop the bleeding. If you have cancer or hyperplasia, an overgrowth of normal cells in the uterus, you may need surgery.

With two other uterine problems, tissue that normally lines the uterus grows where it is not supposed to. In endometriosis, it grows outside the uterus. In adenomyosis, it grows in the uterus's outside walls. Pain medicine may help. Other treatments include hormones and surgery.
