Is celiac disease really associated with inflammatory bowel disease?

Celiac disease (CeD) and inflammatory bowel disease (IBD) are chronic gastrointestinal disorders of inflammatory origin that develop in response to environmental triggers in genetically predisposed individuals. CeD localizes in the duodenal mucosa, where intolerance develops to dietary gluten from wheat, barley, rye, and some varieties of oats. IBD, in turn, is subdivided primarily into Crohn's disease (CD) and colitis, with ulcerative colitis (UC) being the most thoroughly investigated form.
