The second abortion has more risks than the first abortion, such as gynecological inflammation, abnormal menstruation, vaginal relaxation, bad pregnancy outcome, uterine perforation, etc., which need to be reviewed regularly. 1. gynecological inflammation: if the abortion does not pay attention to the prevention of infection, endometritis, pelvic inflammatory disease and other hazards may arise. 2. abnormal menstruation: because abortion has certain damage to the endometrium, some patients may experience menstrual disorders, reduced menstruation and even amenorrhea. If the endometrium is abnormally repaired, resulting in uterine adhesions, it will affect future pregnancies; 3, vaginal relaxation: since abortion is performed in the uterine cavity, if this operation is performed several times, it will lead to vaginal and cervical relaxation, which requires timely rehabilitation physiotherapy; 4, adverse pregnancy outcomes: if the number of abortions is relatively large, it will easily lead to miscarriage, placenta praevia, etc. when pregnant again; 5, uterine complications Complications; 5. Uterine perforation: Because of the relatively thin uterine wall of the second abortion, the chances of uterine perforation are higher, and in case of serious perforation, it may cause haemorrhage and threaten the life of the patient. In order to avoid the above abortion hazards, if you do not intend to get pregnant, it is recommended to take effective contraceptive measures before sex, such as oral contraceptive pills or wearing condoms, to avoid the impact of abortion on the female body.
