If the uterus is not clean, there will be a small amount of residual tissue in the uterus, which will not affect the endometrial cycle, and the endometrial lining will fall off normally and the residual tissue will be discharged with menstruation. If the residual tissue is more, it will cause irregular vaginal bleeding, menstrual bleeding, need ultrasound review, and can be purged again. Failure to remove the uterus can also cause intrauterine infections, such as endometritis, cervicitis, etc., which can easily lead to abdominal pain, increased bleeding, etc., and frequent bleeding can also cause anemia. Therefore, after cleaning the uterus, you need to check the ultrasound regularly to see if the uterus is clean, and at the same time, under the guidance of the doctor, take motherwort and other medicines to promote the discharge of blood. Do not have intercourse within one month after the removal of the uterus, otherwise it will cause intrauterine infection, and when the infection is serious, it will affect the future fertility, so it is necessary to pay attention to hygiene, change underwear and so on.
