Uterine adhesion after abortion surgery may lead to dysmenorrhea, secondary infertility and embryonic arrest. 1. Dysmenorrhea: after abortion surgery, if women have secondary uterine adhesions, this situation will easily lead to menstrual blood can not be discharged normally, menstrual bleeding accumulates in the uterine cavity, and stimulation of the cervix may lead to pregnant women with dysmenorrhea. 2. Secondary infertility: after abortion, if there is uterine adhesion, it will lead to secondary infertility, because when the uterine cavity is sticky, the fertilized egg can’t be normally deposited in the uterine lining, which will lead to long-term failure to get pregnant. 3. Embryonic arrest: when the uterine cavity has adhesions, the fertilized egg cannot develop normally and the embryo stops developing. Adhesions in the uterine cavity after abortion may cause other symptoms, so seek medical attention as soon as possible.
