There have been proven differences between the gut bacteria found in healthy people and people who have joint conditions such as psoriatic arthritis and ankylosing spondylitis. These differences may also apply to other similar conditions (collectively known as spondyloarthritis) which include axial spondyloarthritis and inflammatory bowel disease related arthritis. Our research intends to find out whether we can normalise the gut bacteria in patients with these diseases through dietary changes. Our hope is that this might improve disease activity, pain and inflammation. This survey aims to see whether patients with these conditions would be interested in this research.
