Clinical Information
  • Deviation from or interruption of the normal structure or function of the uterus.
  • Pathological processes involving any part of the uterus.
  • The uterus, or womb, is an important female reproductive organ. It is the place where a baby grows when a woman is pregnant. If you have a uterine disease, the first sign may be bleeding between periods or after sex. Causes of abnormal bleeding 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. Other uterine problems are endometriosis and adenomyosis. In endometriosis, the kind of tissue that lines the uterus grows outside the uterus. With adenomyosis, the tissue grows in the uterus's outer walls. Pain medicine may help; other treatments include hormones and surgery.
