Irritable Bowel Syndrome (IBS) Clinical Trials

Coeliac Disease (CD) is a lifelong autoimmune condition where eating gluten (a protein found in wheat, barley, and rye) causes damage to the small intestine. It affects around 1 in 100 people. Most individuals feel better and their gut heals after switching to a strict gluten-free diet. However, up to 1 in 5 people with coeliac disease continue to experience unpleasant gut symptoms-such as bloating, pain, and diarrhoea-despite following the diet and having a healed intestine. These ongoing symptoms can be very distressing and impact daily life. This study investigates whether a food supplement called Symprove, a probiotic drink containing live good bacteria, can help relieve these ongoing symptoms. Scientists believe that in some people with coeliac disease, the community of bacteria in the gut (called the microbiota) becomes unbalanced, even after going gluten-free. This imbalance (known as dysbiosis) may lead to inflammation, irritation, and symptoms similar to irritable bowel syndrome (IBS). The aim of this study is to test whether Symprove can help correct this imbalance and reduce symptoms. Participants will take Symprove daily and their symptoms, quality of life, and gut bacteria (measured from stool samples) will be monitored over time. The study hopes to answer three key questions: Can Symprove reduce gut symptoms in people with coeliac disease who are in remission? Does it work by restoring a healthy balance of gut bacteria? Are people with more severe imbalance (dysbiosis) more likely to have symptoms? If successful, this research could offer a safe, non-drug option to improve life for coeliac patients who continue to suffer symptoms despite avoiding gluten. It could also help suggest that gut bacteria play a role in ongoing symptoms and are a target for future treatment.
