Test breath testing to guide a lactose-free diet in IBS
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have IBS that meets the ROME IV criteria
- Your IBS symptoms are moderate to severe (IBS-SSS score over 175)
- You currently eat lactose-containing foods (like milk or dairy)
- You do NOT already know you are lactose intolerant or unable to digest lactose
- You have not had antibiotics, probiotics, or certain GI medicines in the last 8 weeks
- You have not followed a lactose-free diet or low-FODMAP diet in the last 8 weeks

Other trials that look related to this one.
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 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.
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.
This study tests a new breath test to see if a digestive enzyme problem (sucrase-isomaltase deficiency) causes IBS symptoms. If you have IBS, this could help find a specific cause and lead to better treatment.
This study looks for signs in your body—like breath and blood tests—that can show how well you are following a special diet for IBS. It aims to find better ways to track diet compliance, which could help make dietary treatments more effective.
This trial tests whether a low-FODMAP diet (a diet that avoids certain carbohydrates that can cause bloating and gas) can improve gut health in people with Irritable Bowel Syndrome. If you have IBS, this diet might help reduce your symptoms and improve how well your intestines work.
