Could a stick of gum ease post-surgery nausea and get bowels moving again?
NCT ID NCT07796529
First seen Sep 01, 2026 · Last updated Sep 02, 2026 · Updated 1 time
Summary
This trial tests whether chewing menthol gum after laparoscopic colorectal surgery can reduce nausea and vomiting, improve bowel function, and speed up recovery. Fifty adults undergoing elective surgery are randomly assigned to either chew menthol gum for 30 minutes, repeated three hours later, on the first three days after surgery, or to receive standard care alone. Researchers track nausea, vomiting, gas passage, and bowel movements during those first three days to see if the gum makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Menthol chewing gum
- What this could lead to
- If it works, menthol gum could become a simple, drug-free way to reduce nausea and speed bowel recovery after colorectal surgery.
- What could go wrong
- This is a small trial with only 50 participants, so results may not apply to everyone. The effect may be modest, and some people cannot chew gum after surgery.
