Managing lactose intolerance with diet and enzyme supplements

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 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 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 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.

This trial tests whether taking a lactase enzyme supplement with meals can reduce bloating and belly discomfort in healthy people who often feel bloated after eating. If you regularly have bloating or a swollen tummy after meals, you might be eligible to join.
