Researchers want to build a detailed map of gut bacteria in people with inflammatory bowel disease (both ulcerative colitis and Crohn disease). By collecting stool, tissue, and blood samples from you over time, they hope to discover which bacteria are linked to your disease and how they connect with your genes and symptoms. This information could eventually help doctors predict how the disease will progress and develop better treatments.
We still don't fully understand why some people with inflammatory bowel disease get sicker than others, or why treatments work differently for different patients. This study aims to fill that gap by discovering the unique bacterial signatures and genetic patterns that drive the disease in each person.

You will visit the research center periodically to provide samples: stool, blood, and tissue samples (the tissue sample is only collected if you're already scheduled for a routine colonoscopy). You'll also complete surveys and questionnaires about your symptoms, mood, and quality of life. Your samples will be analyzed using advanced genetic and bacterial sequencing techniques, and your health information will be linked to those results to identify patterns. The study aims to enroll 1,500 patients and is currently recruiting.
