Could a patch of stomach cells in your throat cause swallowing trouble?
NCT ID NCT07510984
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This observational study is investigating whether heterotopic gastric mucosa (HGM), a patch of stomach-like tissue found in the upper esophagus, is associated with swallowing difficulties (dysphagia) and indigestion (dyspepsia). Researchers will compare symptoms and quality of life between adults with and without HGM who are already scheduled for a routine upper endoscopy. The study aims to better understand the role of HGM in these common symptoms.
