Even with some conflicting data, most studies conclude that celiac disease is more common in IBD patients. Researchers believe the prevalence of Crohn’s disease is higher than ulcerative colitis in patients with celiac disease (Yang et. al). Studies debate the extent of the connection between Crohn’s disease and celiac disease, but all conclude that Crohn’s disease is more common in those with celiac disease than in the general population. With this increased prevalence and many similar symptoms, some researchers suggest that patients over the age of 40 who are anemic or have chronic diarrhea and are diagnosed with celiac disease also have a colonoscopy to test for IBD. Others suggest Crohn’s disease patients try a gluten-free diet.
