Gut Microbiota Fecal Microbiota Transplantation

ClinConnect Summary

This clinical trial is investigating a treatment called fecal microbiota transplantation (FMT) to help relieve symptoms of irritable bowel syndrome (IBS) in patients who do not experience constipation. IBS is a condition that affects the digestive system, and researchers believe that changing the bacteria in the gut may improve symptoms and overall quality of life for patients. In this study, participants will be randomly assigned to receive either FMT from a healthy donor or a placebo treatment, which means they won't know which one they are receiving. The goal is to see if FMT can effectively reduce IBS symptoms and whether it is safe for patients.

To participate in this trial, individuals must be at least 18 years old and have a specific type of IBS, confirmed by a medical examination in the past five years. They should not be taking antibiotics or probiotics within the last two months, nor have certain severe health conditions, such as chronic inflammatory bowel disease or serious heart problems. Participants can expect to undergo the FMT procedure and be monitored for any changes in their symptoms and gut bacteria after the treatment. This study is currently recruiting, and it aims to provide insights into how FMT might be a beneficial option for managing IBS symptoms.
