Chewing Gum for your Guts?

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.

  • Use in colorectal, gynecological, and other abdominal surgeries:
    • Systematic review of 81 Randomized Controlled Trials (RCTs) comparing postoperative chewing gum to any intervention (9,072 patients)
    • Chewing gum resulted in statistically significant decreases in:
        • Time to first flatus (TFF): By 10 hours.
        • Time to first bowel motion (TFBM): By 13 hours.
        • Length of stay (LOS): By 0.7 days.
