However, for those who are combined with serious complications such as postpartum hemorrhage, appropriate delay is needed. After cesarean section, it is necessary to pay attention to adjust the diet under the guidance of the doctor, before the anus is not ventilated, a small amount of liquid diet can be eaten, after the ventilated diet such as rotten noodles and other semi-liquid diet, and gradually increase the protein-rich diet, in order to promote the recovery of the body.
