Managing lactose intolerance with diet and enzyme supplements

This study tests a new way to diagnose lactose intolerance by measuring certain markers in your breath. It may help people who have trouble digesting dairy foods get a faster, easier diagnosis.

This study looks at people with irritable bowel syndrome (IBS) to understand whether it’s connected to lactose intolerance. Participants will be selected based on specific lactose breath and tolerance test results and recent imaging that doesn’t show other causes for symptoms.

This study is screening people with diarrhea-predominant IBS to see if they also have lactose intolerance. If you join, you may get tested to find out whether dairy is worsening your symptoms.

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 if giving lactase enzyme supplements helps preterm babies (born at or before 32 weeks) tolerate their feedings better. If your baby was born early and started feeding within the first few days of life, this study may be a good fit.

This study looks at how lactose intolerance is linked to gut health. It is for adults with ongoing digestive issues like bloating, pain, or diarrhea, to see if their gut lining may be more sensitive.
