Results: Mean time of postoperative intestinal function parameters and hospital stay were significantly shorter in the study group than in control group (P ≤ 0.001). Additionally, after 4, 6, and 8 hours post cesarean section, mean of severity of post-cesarean section gastrointestinal problems were significantly decrease in the study group than in the control group (P ≤ 0.001).
