Summary

This study aims to find a marker in stool or urine that can objectively measure whether people with Irritable Bowel Syndrome (IBS) are sticking to their prescribed diet. Researchers will enroll 94 adults with moderate-to-severe IBS and track their food intake and gut symptoms. The goal is to develop a reliable way to monitor dietary compliance without relying on self-reporting.
