Celiac disease is intolerance to gluten in diet. While classical celiac disease presents in children with diarrhea and growth retardation, it is becoming quite common for celiac disease to present in adults with bloating, gas, fatigue, anemia and osteoporosis.

All patients with undiagnosed digestive disorders should check for celiac disease. Blood tests such as deamidated gliadin peptide antibodies and tissue transglutaminase antibodies are quite accurate for the diagnosis.
