If the recovery after abortion is not good, it may cause long-term sequelae, first of all, abortion will have some trauma to the endometrium. If the endometrium is not repaired properly, it may cause a decrease in the patient’s menstrual flow afterwards, and even the fertilized egg implantation may be affected when the patient gets pregnant again, which may cause infertility. If adhesions of the uterine cavity or cervical canal occur after abortion, it may cause a significant decrease in menstrual flow or even amenorrhea, which may also affect the patient’s subsequent pregnancy. If infection occurs after abortion, it may cause infection in the pelvic cavity and the distant sequel is pelvic adhesions. If the fallopian tubes are affected after pelvic adhesions, it may cause the patency of the fallopian tubes to be affected, increasing the chance of ectopic pregnancy and may cause the patient to become infertile due to the lack of patency of the fallopian tubes.
