- NCT05120752RecruitingPhase 3
Low FODMAP diet trial for IBS without lactose intolerance
This trial tests whether eating a low-FODMAP diet can reduce IBS symptoms in people who do not have lactose intolerance. It aims to improve moderate-to-severe IBS symptoms by changing what kinds of carbohydrates you eat.
Jette, Brussels CapitalAges 18–75 - NCT05293769Recruiting
Food diary questionnaire test for IBS and activity levels
This study checks whether a food questionnaire can reliably estimate what you eat, including certain carbs that can affect digestion (FODMAPs). It also looks at how the results relate to IBS symptoms and your self-reported physical activity.
Jette, Brussels CapitalAges 18–65 - NCT05192603Enrolling by invitation
Low FODMAP vs SSRD diet for IBS symptoms
This study compares two dietary approaches to see which one helps improve symptoms in people with irritable bowel syndrome (IBS). You may be asked to follow a specific diet plan and report how you feel over the study period.

GI Motility diagnosis registry for people with digestion movement problems
This trial is a registry, meaning it collects information about people being evaluated for problems with how the gut moves. It may help doctors better diagnose gastrointestinal motility disorders in the future.
Indianapolis, IndianaAges Any age - NCT03223077Recruiting
Study of gut germs in new Campylobacter stomach illness
This trial studies how your gut germs (microbiome) and gut lining change during a new bout of Campylobacter infection. It may help researchers understand what drives symptoms and how the gut recovers.
Rochester, MinnesotaAges 18–80 - NCT01912313Recruiting
Testing nerve signals in gut samples from IBS patients
This study looks at how nerves behave in small gut tissue samples (biopsies) from people with irritable bowel syndrome (IBS) and healthy volunteers. The goal is to better understand IBS symptoms and what might be driving them.
Leuven, Vlaams-BrabantAges 18–99 - NCT06810518Recruiting
Studying stool test for digestive disease diagnosis
This trial tests a new stool test to measure calprotectin levels, which could help doctors tell the difference between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). If you have symptoms like stomach pain, diarrhea, or weight loss and are about to have a colonoscopy, you may be able to join.
Miami, FloridaAges 22 years+ - NCT07714499Recruiting
Energy use in healthy people vs. those with intestinal failure
