Menstruation usually resumes in about 4-6 weeks after a cleanse. Uterine removal is an invasive operation that involves entering the uterine cavity through the vagina, cervix, and then using a scraper or suction tube to remove the residue or thickened endometrium from the uterine cavity, so the thickness of the endometrium is relatively thin after the removal procedure. In contrast, a woman’s menstruation is produced by the endometrium and is influenced by the level of sex hormones in the body. Therefore, since the endometrium after the cleansing is basically in the state just after menstruation, it needs to be repaired gradually, and the recovery of the endometrium of normal women is between 4-6 weeks, so most women will also resume menstruation in about 4-6 weeks after the cleansing. If menstruation does not resume for a long time, it cannot be excluded that the cleansing has caused serious damage to the endometrium, so it is recommended to consult a doctor promptly to improve the relevant examination and then clearly diagnose and treat the disease. In addition to the use of drugs to promote the recovery of the uterus and prevent infection, oral estrogen and progesterone combination can also be taken after the operation, which can not only adjust the growth of the endometrium, but also make menstruation more regular.
