A woman should not have more than 3 abortions in her lifetime, but there are large individual differences and specific problems need to be analyzed. Abortion can cause great harm to the health of the female body. It will mainly lead to low menstrual flow, secondary infertility, endometriosis, gynecological inflammation and other problems. 1. Low menstrual flow: women who have more abortions cause damage to the lining of the uterus, and the thinning of the lining of the uterus leads to low menstrual flow. 2. Secondary infertility: the operation inside the uterine cavity is easy to make the endometrium thin, and in the local formation of trauma, easy to cause the uterine cavity adhesion, not easy to get pregnant. 3. Endometriosis: the abortion process can easily cause the blood in the uterus to flow backward through the fallopian tube to the pelvis, and then form a planting, causing endometriosis, which manifests itself as abdominal pain, irregular menstruation and so on. 4. Gynecological inflammation: abortion is an invasive surgery, and the process of abortion may lead to traumatic infection, causing pelvic inflammatory disease and other gynecological inflammatory diseases. So women should pay attention to contraception when they are not ready to have children. After an unwanted pregnancy, abortion must be operated in a regular hospital with a qualified doctor.
