An observational study in Inflammatory Bowel Disease (IBD), Irritable Bowel Syndrome (IBS) and Celiac Disease, sponsored by Mayo Clinic. Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-06-12.
Sponsored by Mayo Clinic · Observational
The goal of this observational research study is to determine how diet contributes to various gastrointestinal related conditions.
The main question investigators aim to answer is:
Are host genetics, diet, and microbiome all important determinants of GI disorders, and how their relative contribution varies among individuals and populations.
1,550 studies on the registry are indexed under Inflammatory Bowel Diseases; 426 are open to participants now.
This study's planned enrollment of 4,001 is above the median of 140 across 626 observational studies indexed under Inflammatory Bowel Diseases.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
