Breath test for small intestinal bacterial overgrowth
Part of Digestive system clinical trials.
This study tests a methane and hydrogen breath test to help diagnose small intestinal bacterial overgrowth (SIBO) in people with digestive symptoms compared to healthy individuals. If you have ongoing belly problems like bloating, pain, or diarrhea, this test might help find the cause.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You have ongoing abdominal symptoms like bloating, early fullness, diarrhea, constipation, or belly pain, or you are a healthy person without these symptoms.
- You can complete a breath test and symptom questionnaire, with or without help from a provider.
- You are willing to sign a consent form.
- You have not had recent cancer, certain digestive diseases, surgeries, or infections (details during screening).
- You have not taken antibiotics in the last 4 weeks, or certain other medications in the last 1-2 weeks.

This study tests a probiotic pill for people with bothersome bloating and an abnormal hydrogen breath test. It aims to see if the probiotic helps improve gut symptoms.
This is a research registry that collects small-bowel fluid samples from people being tested for “SIBO” (an overgrowth of bacteria in the small intestine). It aims to describe what bacteria are present and how results differ between people with suspected SIBO and others having similar tests for other reasons.
This early study tests whether fecal microbiota transplant (a stool donation placed into the gut) is safe and practical for children with small intestinal bacterial overgrowth (SIBO). It may help reduce SIBO symptoms, but the main goal is to see if the treatment and study steps work well.
This study tests how Rifaximin (a medicine for SIBO) affects the bacteria and other substances in your gut. You'll swallow a small capsule that collects samples as it travels through your digestive system, so researchers can see how your gut changes during treatment.
This study checks whether breath tests can help identify small intestinal bacterial overgrowth in people with reflux-like symptoms (heartburn or regurgitation). If you qualify, you may be asked to avoid certain medicines and treatments for a short time so the test results are accurate.
This study uses breath tests to check for small intestinal bacterial overgrowth (SIBO) in people with chronic pancreatitis who still have stomach issues despite taking enzyme pills. It aims to find out if SIBO is causing your symptoms.
