Can a simple spray quench Post-Surgery thirst?
NCT ID NCT07728500
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
After bariatric surgery, patients often feel intense thirst due to fasting and anesthesia. This trial tests whether spraying menthol or cold water inside the mouth can reduce that thirst and improve comfort. About 180 adults who have had bariatric surgery will be randomly assigned to receive menthol spray, cold spray, or standard care. Researchers will measure thirst levels and comfort scores shortly after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- menthol spray and cold spray
- What this could lead to
- If effective, menthol or cold sprays could offer a simple, drug-free way to relieve thirst and improve comfort after bariatric surgery.
- What could go wrong
- This is a small, early-stage trial. The sprays may not significantly reduce thirst or improve comfort compared to standard care, and individual responses may vary.
