After a cesarean section, you may be able to move around more, apply hot compresses, or use medication to promote gas flow. After a cesarean section, normal bowel movement is determined by passing gas because of the slight irritation of the bowel from the surgery and the use of anesthesia medications, which can lead to decreased bowel function and slower peristalsis. Gas is usually passed between 24 and 48 hours, or a little later in some cases. It is important not to stay in bed all the time after the operation, but to get out of bed to promote peristalsis. Be careful not to eat food that may cause bloating, such as milk, etc. You can also apply hot compresses and massage the abdomen to promote bowel movement, and be careful not to touch the wound. If there is no gas for a long time, you can also use drugs such as Houpu Qiqi Compound to promote gas. Drugs should be used under the guidance of a physician.
