Cesarean sections are limited to three and try not to exceed more than three. Cesarean sections are usually performed on the lower part of the uterus, which becomes thin after pregnancy due to the effects of fetal compression. The more times of cesarean section, the greater the damage to the lower part of the uterus, resulting in the localization of poor blood circulation. If the number of cesarean sections is high, it is easy to cause uterine rupture. The more times a woman has a cesarean section, the greater the chance of having a scarred pregnancy when she gets pregnant again. The more times a woman has a cesarean section, the more severe the pelvic adhesions are, and the more likely she is to damage the tissues and organs in the pelvis when she has another operation. The more C-sections you have, the more likely you are to cause placental implantation and the greater the chance of hemorrhage during another C-section. Try not to have more than three cesarean sections, and contraception should be used for two years after the cesarean section.
