Celiac disease (CD) is one of the most common causes of malabsorption. It is an immune-mediated disease manifested by diarrhea, steatorrhea, flatulence, and weight loss, caused by ingestion of gluten containing diets. The disease has typical small intestinal biopsy features of villous atrophy, crypt hyperplasia, and intense inflammation of the mucosal layer. The disease is rarely associated with Crohn's disease (CRD). Studies on the impact of CD on the natural history of inflammatory bowel disease (IBD) have shown that the natural course of CRD is not influenced by coexistent CD. We report a case of 54-year female who presented with diarrhea and weight loss. On initial evaluation, CD was diagnosed, and responded to gluten-free diet (GFD). Later on, she developed joint pains and her diarrhea recurred. Further evaluation revealed coexistence of CRD. The treatment of CRD was also initiated and this led to marked improvement in the symptoms of the patient.
