Recruiting studies
- NCT06197334Recruiting
Recording stomach and gut signals with skin sensors
This study uses small sensors placed on your belly to record electrical signals from your stomach and intestines. It may help doctors better understand conditions like Crohn's disease and other digestive issues without using needles or inside-the-body tests.
Vandœuvre-lès-Nancy, CHRU de NancyAges 18 years+ - NCT06057415Recruiting
Gut nerve stimulation study for high-risk newborns
This study tests whether stimulating the nerves in the gut can help improve digestion in high-risk newborns, specifically those born very early or with a diaphragmatic hernia. It takes place at Amalia Children's Hospital and aims to find a way to help these babies' intestines work better.
NijmegenAges Up to 2 days - NCT05501028Enrolling by invitation
Audio-recorded gut symptom interview to help diagnose FGIDs
This trial uses natural-language conversations (spoken interactions) to improve how clinicians evaluate and diagnose functional gastrointestinal disorders, a group of conditions that affect the gut. If you are scheduled for a GI clinic visit or a diagnostic endoscopy, your recorded responses may help build better evaluation tools.
Boston, MassachusettsAges 18 years+ - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05846802Recruiting
Gastroparesis and stomach symptoms registry for adults
This registry is for adults with long-lasting stomach emptying problems or related symptoms, helping researchers better understand patterns of nausea, pain, and fullness. You may be able to join if you meet specific symptom and test results, and can complete a stomach-emptying scan.
Scottsdale, ArizonaAges 18–85 - NCT06834126RecruitingPhase 1
Papaverine with radiation for advanced rectal cancer
This trial tests if adding papaverine (a drug) to radiation therapy can help people with locally advanced rectal cancer avoid surgery and keep their rectum. It is for patients who have already had chemotherapy and want a non-surgical approach.
Duarte, CaliforniaAges 18 years+ - NCT06359106RecruitingPhase 4
Oxygen levels and lung health in older surgical patients
This trial tests whether a lower or higher oxygen concentration during surgery can help protect lung function in older adults. It focuses on people 65 and older having laparoscopic gastrointestinal surgery.
Shenyang, LiaoningAges 65 years+ - NCT07590895Recruiting
Low-FODMAP Diet for Endometriosis Pain and Bowel Symptoms
This study tests whether a low-FODMAP diet (a way of eating that limits certain hard-to-digest foods) can reduce pelvic pain, improve quality of life, and help bowel symptoms in women with endometriosis. Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus, often causing pain and digestive problems.
MilanAges 18–45 - NCT05812339Enrolling by invitation
Mapping tests for stomach symptoms using body-surface sensors
This study checks whether a noninvasive “mapping” test placed on the belly and chest can help tell apart people with certain upper stomach symptoms from healthy controls. It may help researchers better understand stomach function and symptoms without relying only on invasive tests.
Calgary, AlbertaAges 18 years+ - NCT07519915Recruiting
Understanding Nerve Stimulation for Bowel Problems in Children
This research study looks at using sacral neuromodulation—a treatment that uses mild electrical stimulation of nerves in the lower spine—to help children with bowel movement problems. Researchers want to understand how well this treatment works and what improvements matter most to patients and families.
ErlangenAges 3–18 - 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 - NCT06316245Recruiting
Recovery after major gastrointestinal surgery
This study looks at how well you recover after major or intermediate surgery on your stomach, intestines, colon, or rectum. It measures your ability to do daily activities and how many days you spend at home (instead of the hospital) in the first 30 days after surgery.
Istanbul, FatihAges 18 years+ - NCT07412379Recruiting
Predicting recovery after cancer surgery for older adults
This study looks at how older adults (65+) with digestive tract cancers respond to surgery aimed at a cure. Researchers want to see what factors affect recovery and quality of life after the operation.
BogotáAges 65 years+ - NCT07453823Recruiting
Synbiotic for gut health in overweight adults
This trial tests a combination supplement (a synbiotic) to see if it can improve gut function and gut bacteria in middle-aged and older adults who are overweight and have constipation. If eligible, you take the supplement daily and report how your digestion feels.
Cork, BlackpoolAges 50–70 - NCT05307367Recruiting
Study exercise and body muscle changes in advanced lung cancer
This study looks at why cancer can cause loss of muscle in people with advanced non–small cell lung cancer, and whether exercise can improve or explain those muscle changes. You may be asked to do physical testing and answer questionnaires while receiving standard palliative cancer treatment.
Copenhagen, DKAges 18–100 - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.

Common questions
- Are there clinical trials for gastrointestinal function?
- Yes. Clin2 currently lists 40 recruiting gastrointestinal function 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 gastrointestinal function 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 gastrointestinal function 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.
