First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 8 times
Summary
This study aims to collect medical data and biological samples (blood, urine, stool, and tissue) from up to 4,000 adults with known or suspected gastrointestinal diseases. Participants receive standard medical care at the NIH, and any extra samples or leftover tissue from procedures like endoscopy are used for future research. The goal is to build a resource to help scientists better understand and treat these conditions.
