Recruiting studies
- NCT05808036Recruiting
Test a diet app for IBS symptoms using the DOMINO diet
This trial studies whether a specific diet plan delivered through a phone app (the DOMINO diet) can improve symptoms in people with irritable bowel syndrome (IBS). It may help by changing what you eat to reduce gut symptoms, compared with standard care rules in the study.
LeuvenAges 18–70 - NCT05796388Recruiting
Virtual reality and linaclotide for IBS with constipation
This study tests whether virtual reality (VR) plus linaclotide can improve symptoms and quality of life in adults with IBS-C (IBS with constipation). You may be asked to use VR and take a study medicine, while doctors check that your IBS diagnosis fits strict criteria.
Jacksonville, FloridaAges 18–70 - NCT05776914RecruitingPhase 2
Fecal transplant to treat moderate to severe IBS symptoms
This trial tests whether putting stool (fecal microbiota) from a donor into your bowel can improve symptoms in people with IBS who are not IBS-C. It may help by changing the gut bacteria that can influence IBS symptoms.
Rochester, MinnesotaAges 18–70 - NCT05573542Enrolling by invitation
Study early Parkinson signs in people with IBS
This study looks for early clues of Parkinson’s disease in people who have IBS (irritable bowel syndrome), and compares them with people without IBS. The goal is to understand whether gut symptoms or test results can help spot Parkinson’s earlier.
ÖrebroAges 18–85 - NCT05519683RecruitingPhase 2/Phase 3
Home electrical stimulation for constipation IBS pain
This trial tests whether a home device that uses mild skin electrical stimulation can reduce belly pain from IBS with constipation. It also checks whether the treatment is safe and helpful for symptom relief over the study period.
Ann Arbor, MichiganAges 18 years+ - NCT04974593RecruitingPhase 3
Test breath testing to guide a lactose-free diet in IBS
This trial studies whether a breath test (hydrogen/methane lactose testing) can predict who with IBS will improve on a lactose-free diet. If you have moderate-to-severe IBS and regularly eat lactose-containing foods, the test result may help tailor your diet approach.
Jette, Brussels CapitalAges 18–75 - 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.
MalmöAges 18–70 - NCT04506593Recruiting
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
This study looks at how the body uses energy (calories) in people with intestinal failure compared to healthy controls. The results may help improve nutritional care.

Common questions
- Are there clinical trials for irritable bowel syndrome?
- Yes. Clin2 currently lists 110 recruiting irritable bowel syndrome studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a irritable bowel syndrome trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a irritable bowel syndrome trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
