Lactose intolerance and irritable bowel syndrome study
Part of Digestive system, Genetic & congenital, Hormones & metabolism clinical trials.
This study looks at how lactose intolerance relates to irritable bowel syndrome (IBS) in people who already have both. It may help doctors understand the link and improve treatment. Participants will have their lactose digestion checked with special breath tests.
Summary written for real people, not researchers, by Clin2.

Other trials that look related to this one.
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.
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.
This study checks whether people with IBS (diarrhea type) are also lactose intolerant. The goal is to see if avoiding lactose helps with IBS symptoms, so they can better manage their condition.
This study tests whether some IBS symptoms are linked to a certain gut bacteria and an immune reaction. It aims to understand the cause of IBS to find better treatments.
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 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.
