Long-term effects need to be monitored, and short-term uterine scar pregnancies are at high risk The long-term effects of cesarean delivery on pregnant women need to be followed and monitored over a long period of time, and research in this area is just beginning in China. But in some of the data, she has seen some longer-term effects of cesarean delivery on pregnant women. Uterine scar pregnancy is one of them. Uterine scar pregnancy is commonly referred to as a pregnancy in which a woman who has had a C-section becomes pregnant again and the fetus happens to be implanted in the C-section scar of the uterus. According to data, uterine scar pregnancy is a relatively rare phenomenon, with an incidence of about 1 in 1,800 to 1 in 2,226. The risks posed by a uterine scar pregnancy to the pregnant woman are considerable. In the event of a miscarriage or termination of pregnancy, the pregnant woman may face hemorrhage, which in severe cases may require removal of the uterus and even endanger her life. “Uterine scar pregnancy is a risk that is of increasing concern and importance to obstetricians and gynecologists today.” In addition to this, cesarean sections have the potential to cause scarred endometriosis of the abdominal wall. “Normally, the endometrium should be implanted in the uterus, and some cells of the endometrium will be shed during the cesarean section and planted on other parts of the uterus, and if planted on the abdominal wall of the uterus there is a risk of scar endometriosis of the abdominal wall, and with each menstrual period, the scar endometriosis lesion of the abdominal wall will also be red, swollen, and enlarged, and there is even significant pain. In this case, there is a risk of infertility, menstrual disorders, and other symptoms.” Cesarean delivery may also indirectly induce mastitis. “Mothers who give birth by cesarean section have wounds on the abdominal wall, and when breastfeeding, some positions are restricted, causing difficulties in breastfeeding. Usually, mothers who give birth by caesarean section will adopt a lying position for breastfeeding, when the child is poorly attached to the nipple, which may cause nipple rupture, nipple surface skin contusion, so that breastfeeding fails, and may even induce mastitis.”
