Celiac disease (CD), also known as gluten-sensitive enteropathy as well as two older and no longer recommended terms,3 nontropical sprue and celiac sprue, is a chronic immune-mediated disorder induced by dietary gluten in genetically susceptible individuals. In CD patients, the ingestion of gluten results in the development of small intestinal mucosal villous atrophy with crypt hyperplasia and mucosal inflammation. Patients may be asymptomatic or may manifest classic malabsorptive symptoms of abdominal pain, bloating, weight loss, diarrhea, and steatorrhea. They also may present along a spectrum with more subtle gastrointestinal and/or extraintestinal symptoms and signs of the disease; virtually every body system can be affected.

It is very important for the primary care physician to recognize the early signs and symptoms and to initiate the appropriate workup and treatment in coordination with consulting specialists to prevent further morbidity and mortality.
