Does chewing gum after surgery improve bowel function? You’ll be surprised with the answer!
Bottom Line: Chewing gum in post abdominal surgery patients shortens time to first flatus (by 10 hours), time to first bowel motion (by ~1/2 day), and length of hospital stay (by~0.7 days). For every five patients treated, one fewer will develop ileus. Chewing gum in non-post-surgical constipation has not been studied.
