If menstruation is present again after six months of menopause, it is necessary to determine the cause according to one’s age. For example, if menstruation is present again after menopause, it is necessary to pay high attention to the possibility of endometrial inflammation, endometrial hyperplasia, including precancerous lesions of the cervix and uterine fibroids. If the bleeding occurs again instead of menstruation, it is necessary to go to the gynecology department for an abdominal ultrasound examination to determine whether there are abnormalities in the cervix, both adnexa and the uterus, as well as TCT and HPV cancer prevention tests; if necessary, endometrial scraping should be performed to remove some tissues for pathological tests. For example, if the patient is young and has stopped menstruating for half a year without menopause, she may have endocrine hormone disorders. It is recommended to check endocrine hormones to rule out hyperprolactin and polycystic ovary syndrome, and depending on the situation, short-acting oral contraceptive drugs can be used for treatment.
