Gut bacteria study for constipation-predominant IBS with methane
Part of Digestive system clinical trials.
This study looks at the gut bacteria in people with irritable bowel syndrome (IBS) who have constipation and produce high levels of methane gas. It aims to understand how methane relates to symptoms and may guide future treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have IBS with constipation or mixed constipation and diarrhea, not mainly diarrhea.
- You have high methane levels (≥10 ppm) on a breath test.
- You are 18 or older.
- You have not taken antibiotics or probiotics in the last 3 months.
- You have not had major abdominal surgery (except appendix or gallbladder removal).
- You do not have other bowel diseases like celiac, inflammatory bowel disease, or colorectal cancer.

Other trials that look related to this one.
This study compares the bacteria and natural chemicals in the intestines of people with irritable bowel syndrome (IBS) to those without it. It aims to find differences that could help improve IBS diagnosis or treatment.
This study tests how two types of fiber (inulin and methylcellulose) affect your gut when eaten regularly. You'll eat provided meals and have your breath tested to see how your gut breaks down the fiber.
This trial tests whether a fecal microbiota transplantation (FMT), which transfers healthy bacteria from a donor into your gut, can reduce severe irritable bowel syndrome (IBS) symptoms. FMT is being studied as a possible new treatment for people with IBS that hasn't improved with other treatments.
This trial tests whether transferring stool bacteria to the gut (fecal microbiota transplantation) can reduce symptoms of irritable bowel syndrome with constipation. It may help by changing the gut microbiome, but you must meet safety and health requirements.
This trial tests a new treatment called SMT04 for people with irritable bowel syndrome (IBS), specifically the diarrhea or mixed types. It may help reduce symptoms like abdominal pain and changes in bowel habits.
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.
