If there is irregular bleeding before menopause, endocrine hormone imbalance or gynecological disorders may be present. It is recommended to go to the hospital for an ultrasound to determine if there are endometrial polyps, ovarian cysts, fibroids, or ovarian hypofunction. Because all these causes may cause the chance of abnormal bleeding to occur, less medication should be administered, otherwise it will affect the health of the body. For example, if there is irregular bleeding after menopause, it should be taken seriously because when there are cervical diseases, including endometrial hyperplasia or cervical cancer, it may cause irregular bleeding, and it is also necessary to go to the hospital for endoscopy, including TCT and HPV cancer screening to rule out any abnormalities and to deal with them according to the situation.
