How acid-reducing medicine affects gut bacteria in healthy adults
This study looks at how acid-reducing medicines called proton pump inhibitors (like omeprazole) affect the natural bacteria in your gut. You'll be asked to take a small capsule that collects samples from your digestive system to see how these medicines change your gut health.
Summary written for real people, not researchers, by Clin2.

This study measures how your diet affects the bacteria in your gut. It is for healthy adults and people with irritable bowel syndrome (IBS) to see if certain foods change gut bacteria differently.
This study tests whether a probiotic called Lactobacillus rhamnosus GG can improve gut bacteria changes caused by proton pump inhibitors (acid-reducing medicines). It mainly involves people who are otherwise healthy and do not currently have ongoing stomach or gut symptoms.
This study looks at how proton pump inhibitors (PPIs), a type of medicine that reduces stomach acid, affect the natural bacteria in the gut of children and teenagers. It may help us understand if PPIs change gut health, which could guide future treatment decisions.
This study tests if the medicine omeprazole, commonly used for acid reflux, changes the bacteria in the gut. It may help doctors understand how this treatment affects people with obesity and reflux, and why some people might benefit more than others.
This trial tests whether taking probiotics (healthy bacteria) and zinc supplements together can help reduce symptoms of acid reflux (GERD) and improve the health of your esophagus. It is a phase 4 study, which means these treatments are already in use, and this trial looks at how well they work in real-world patients.
This study tests whether it is safe and helpful to reduce or stop daily high-dose heartburn medications (called PPIs) in patients who might not need them anymore. It is for adults who take a strong PPI every day and can communicate in German.
