Celiac disease (CD) is an immune-mediated disorder that develops in genetically-predisposed individuals, which is triggered by eating gluten that is present in wheat, barley, and rye (1,2). Gluten causes an immunological reaction in the small intestine, which damages the villi and leads to malabsorption (including diarrhea, steatorrhea, iron-deficiency anemia and weight loss or growth failure) and other health complications including chronic fatigue, headache and abdominal pain (1,2).
