It is possible for the rectus abdominis muscle to separate during labor, as it is not necessarily related to the mode of delivery. The separation of the rectus abdominis muscle is mainly due to the increase in uterine size after pregnancy, which causes pressure on the rectus abdominis muscle. When the uterus shrinks rapidly after delivery, the rectus abdominis muscle will be separated, but the exact severity and shape of the separation varies from person to person. However, the severity and shape of the separation depends on the individual. The separation of the rectus abdominis muscle has nothing to do with the mode of delivery, so it can be caused by either a normal delivery or a cesarean section. After a normal delivery, the rectus abdominis muscle will gradually converge to the midline, and normal abdominal wall tension will be restored in about six to eight weeks. There is no need to worry too much, and if necessary, rehabilitation training can be carried out. If the condition is serious, surgery can be considered, such as rectus abdominis repair. It is recommended that you seek medical attention promptly to avoid delaying your condition.
