Transforming IBS-D Treatment

Are you ready to take control of your IBS-D symptoms and be part of a groundbreaking study that could change the game for IBS treatment?

Welcome to Tummy MOT's latest study.

What is the study?

We’re shaping the future of IBS treatment.

The study is a pioneering clinical trial being carried out by our experts at The Functional Gut Clinic. We’re investigating a new investigational medicinal product, to help manage symptoms of diarrhoea-predominant irritable bowel syndrome (IBS-D).

This study will help us to understand how the product affects IBS symptoms and the gut microbiome, potentially offering new hope to people experiencing IBS-related tummy troubles.

And we need you!

This is your opportunity to be part of cutting-edge research in IBS treatment, get access to a potential new treatment option, and get the full support of our gut experts.

By joining in with the study, you’ll be helping us advance the science and pave the way for improving the lives of people with IBS.
