Cesarean section generally refers to cesarean section. There are generally no obvious sequelae after cesarean section in old age, but sequelae such as scar diverticulum, pelvic adhesion and endometriosis may occur in childbearing age. 1. Keloid diverticulum: after the operation, a wound will be left in the uterine incision area, and it is easy to form a scar, if the wound area is not properly cared for, poor healing may occur, and in severe cases, keloid diverticulum may be caused. 2. Pelvic adhesion: If there is no good local care after the operation, and there is infection in the uterine cavity, it is easy to cause pelvic adhesion, especially for women who have had many cesarean sections, the chance of pelvic and abdominal adhesion will increase. 3. Endometriosis: If the endometrium is accidentally brought to the incision site during the cesarean section operation and planted in the incision site, endometriosis is easily formed. After the cesarean section operation, you must take good care of the local area, and if there is any abnormality, you need to consult a doctor in time.
