 Introduction; Cesarean section is the most common surgery among women which is associated with postoperative central nervous system CNS changes, leading to decreased bowel movements. Postoperative ileus is defined as transient cessation of coordinated bowel motility after surgical intervention. It Is one of the major problems of post-abdominal surgery which delays hospital discharge, causes abdominal pain, abdominal distension, inability to start oral feeding, breastfeeding, and eventually increases the cost of hospital care. Historically, professionals of gynecology and obstetrics waited until gut function returns allowing oral or entered feeding, characterized by symptoms such as bowel sounds, first flatus or stool, and feeling of hunger. Chewing gum can stimulate the stomach, enhances gastric secretion, increases peristaltic bowel movements and finally hastens recovery from ileus. It has also been recently considered by researchers as a strategy toward ileus reduction. It seems that a necessity is felt for more investigation on such a least-expensive physiological method in stimulating the return of bowel function.
