Coeliac disease is treated by maintaining a gluten-free diet for one year.
Up to 30% of people often continue having or redeveloping symptoms after starting a gluten-free diet
Refractory coeliac disease should not be confused with the persistence of symptoms despite gluten withdrawal caused by transient conditions derived from the intestinal damage, which generally revert or improve several months after starting a gluten-free diet, such as small intestinal bacterial overgrowth, lactose intolerance, fructose, sucrose, and sorbitol malabsorption, exocrine pancreatic insufficiency, and microscopic colitis among others
