Chewing_gum_stick

Sham feeding with chewing gum has been shown to promote bowel motility. This may reduce symptoms of abdominal discomfort, nausea, and vomiting sometimes associated with bowel preparation for colonoscopy.

In a study by Lee J et al, 131 patients were randomized to either bowel prep with polyethylene glycol (PEG) solution alone or PEG plus sugarless chewing gum.

The result: The chewing gum group reported lower abdominal discomfort, nausea and vomiting. It also took the group a shorter time to ingest the PEG solution.

Take Home Point: Gum chewing may improve the tolerability of PEG-based bowel cleansing agents for colonoscopy.
