Gut health and inflammatory bowel diseases

Research shows a number of bowel diseases linked to inflammation have been correlated with changes in the gut microbiome.

Recent advances in technology have led to a richer understanding of the role the gut microbiome plays in inflammatory bowel diseases, such as Crohn’s disease, Irritable Bowel Syndrome, Ulcerative Colitis and colorectal cancers. For example, functional gene counts and species diversity are now known to be considerably lower in patients with Crohn’s disease.

We see a healthier future for the many Australians affected by IBD. Find out how we're making a difference.
