Irritable Bowel Syndrome With Diarrhea Fecal Microbiota Transplantation Randomized Controlled Study Mental Health Comorbidity Young Adults

ClinConnect Summary

This clinical trial is looking into a treatment called Fecal Microbiota Transplantation (FMT) for young adults who have Irritable Bowel Syndrome with Diarrhea (IBS-D) and mental health issues like depression and anxiety. The goal is to see if FMT can help improve their gut health and mental well-being compared to a placebo (an inactive treatment). The trial is set to start soon and will involve participants aged 18 to 29 years old who have been experiencing IBS-D symptoms for at least six months. To join, individuals will need to have a diagnosis of IBS-D and some level of depression or anxiety, but they must also meet certain health criteria, such as having no serious gastrointestinal diseases.

If someone decides to participate, they will need to keep a diary about their symptoms and follow the study guidelines, which include sticking to their usual diet and lifestyle throughout the trial. It’s important to know that this study excludes people with certain health conditions, including severe mental disorders, other gastrointestinal diseases, or those who have had recent surgeries that could affect the results. Participants will be monitored closely for safety, and their experiences will help researchers understand the potential benefits and risks of using FMT for treating IBS-D and related mental health issues.
