Semaglutide users may face hidden surgery risk, ultrasound study finds
NCT ID NCT06263595
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used ultrasound to measure stomach contents in 94 patients before surgery, comparing those on semaglutide (a GLP-1 drug for diabetes/weight loss) to those not taking it. The goal was to see if semaglutide increases the risk of a 'full stomach' despite following fasting rules, which could lead to dangerous aspiration during anesthesia. Researchers hope the findings will help create safer fasting guidelines for these patients.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
semaglutide
What this could lead to
If successful, this could lead to better fasting guidelines for patients on semaglutide before surgery, reducing the risk of aspiration pneumonia.
What could go wrong
This is a small, completed observational study (94 participants) that only measures stomach volume, not actual aspiration events. Results may not apply to all patients or settings.
