Stomach sensor may unmask hidden effects of weight-loss drugs
NCT ID NCT06401746
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This study tests whether a non-invasive device called Gastric Alimetry can detect changes in stomach muscle activity caused by semaglutide (Ozempic). Researchers will measure stomach electrical signals and symptoms in people with and without diabetes before and after taking the weekly injection. The goal is to understand why semaglutide can cause digestive problems like bloating and delayed stomach emptying. The study is a small pilot, so it aims to gather early clues rather than provide final answers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gastric Alimetry, a non-invasive device that records stomach electrical activity
- What this could lead to
- If it works, this could help explain why semaglutide causes stomach side effects and lead to better ways to predict or manage them.
- What could go wrong
- This is a small pilot study with only 9 participants, so results may not apply broadly. The device measures stomach activity, but it is not yet proven to predict symptoms.
