Abortion surgery, if done more often, is mainly prone to cause gynecological diseases. The uterus is a relatively important organ for women, and repeated abortions will affect the lining of the uterus and the cervix. First of all, it is the effect on the endometrium. Repeated abortions will cause different degrees of endometrial defects and thinning, which will lead to irregular menstruation, causing less menstrual flow or irregular menstruation. If the endothelial loss is particularly severe, it may also lead to cervical adhesion and uterine cavity adhesion. Secondly, after having an abortion, it is easy for the patient to get infected with cervical erosion as well as vaginal inflammation. If the cervix is stimulated by inflammation and instruments for a long time, it is easy to develop lesions. Therefore, it is necessary to have fewer abortions and take proper contraceptive measures.
