Australia has one of the highest rates of inflammatory bowel disease (IBD) in the world; its prevalence has increased significantly over the past 20 years and is projected to increase by > 250% from 2010 to 2030, to then affect 1% of the population. Although advances in clinical practice have led to increased identification, this increase is thought to be due to urbanisation of communities, with changes in sanitation and dietary practices. Such changes seen in Asia over the past 20 years have mirrored the rapidly increasing rates of IBD in the Western society, lending support to the “hygiene hypothesis”, and explaining, in part, the increasing burden of IBD on Australian health care due to our high rates of immigration.
