Polyps in the uterus may refer to endometrial polyps, which are mainly caused by localized overgrowth of the endometrium due to elevated estrogen levels in the body or inflammatory factors. Endometrial polyps are a relatively common gynecological disease caused by localized overgrowth of the endometrium, which can easily cause symptoms such as increased menstrual flow, prolonged menstrual period, irregular vaginal bleeding, and increased vaginal discharge. The cause of endometrial polyps is not yet clear, but may be related to high estrogen levels and inflammatory factors. 1. High estrogen level: If the estrogen level in a woman’s body is elevated, it will lead to endometrial hyperplasia. If estrogen is at a high level for a long time, the lining of the uterus may overgrow, resulting in the formation of endometrial polyps. 2. Inflammatory factors: If a woman has endometritis, labor abortion, puerperal infection, infection after uterine surgery, etc., will cause a certain amount of stimulation of the endometrium, which may also lead to the occurrence of endometrial polyps.
