The main purpose of the restraint belt after cesarean delivery is to tighten the abdomen of the mother, to prevent the abdomen from shaking too much to affect the healing of the wound, and to prevent the pain of the wound in the uterus caused by shaking too much. So seven days after the cesarean delivery, the wounds on the stomach basically heal and the uterus gradually shrinks, so after seven days you can stop using the restraint belt. There is a difference between the restraint belt and the belly band used for weight loss, the restraint belt is relatively weak in elasticity and only slightly tightens the abdomen of the mother, while the belly band has a strong abdominal effect, which is detrimental to postpartum recovery, so be careful to use the restraint belt instead of the belly band after cesarean delivery.
