Normally, there will be no menstruation and no abnormal bleeding after menopause. If there is bleeding three years after menopause, it is not menstruation, but abnormal bleeding, so it should be taken seriously to rule out any lesions in the uterine organs. For example, the presence of endometrial hyperplasia, uterine fibroids, human papillomavirus infection, or cysts in the adnexal area, as these factors may cause abnormal bleeding. It is recommended to go to the gynecology department for an abdominal ultrasound to rule out any abnormalities in the uterus, both adnexa, including the cervix, and if necessary, endometrial scraping or hysteroscopic endometrial scraping to determine what kind of medication to take orally to stop the bleeding based on the laboratory results. Because such bleeding can cause other factors, such as the chance of precancerous lesions and endometrial cancer, it is important to pay great attention to it.
