Primary Investigator: 
Mark Silverberg, MD
Enrolment: Ongoing

Objective: The objective is to understand how diet and other biomarkers may affect the gut microbiome in IBD.

Expectation: This research will lead to a better understanding of why the disease occurs, easier diagnostic tools that may avoid the need for colonoscopies, better therapies or even a cure.

Eligibility: Anyone who has a confirmed diagnosis of IBD (either Crohn's Disease or ulcerative colitis) and has a scheduled colonoscopy for their routine care. Also, anyone who does not have IBD (i.e. Crohn's Disease or ulcerative colitis) or have a family history of IBD, has a scheduled colonoscopy and is willing to participate as a healthy control.
