To promote menstruation, progestin or a combination of estrogen and progestin can be taken, mainly to change the hormone levels in the body to cause withdrawal bleeding from the endometrium, thus creating an artificial menstrual cycle. It is not recommended to take medication for a long time to promote early menstruation. Taking medication from outside may cause disorders in the endocrine system of the body, which may lead to disruption of the menstrual cycle, increase or decrease in volume, and may also lead to amenorrhea. Some women are taking sex hormones for a long time, which may lead to tumors in the reproductive system, for example, long-term use of estrogen may lead to abnormal hyperplasia of the endometrium, which may lead to endometrial cancer. Usually, you need to relax, avoid overwork, avoid alcohol abuse and eat reasonably to effectively prevent the occurrence of menstrual disorders.
