Presentation of celiac disease.

The mode of presentation of patients with celiac disease has changed dramatically over the recent decades, with diarrheal or classic presentations becoming less common. This trend is most markedly seen in children, whose main presentations include recurrent abdominal pain, growth issues, and screening groups at risk. Among adults, presentations include diarrhea, anemia, osteoporosis, and recognition at endoscopy performed for gastroesophageal reflux disease, as well as screening. The groups most commonly screened include family members of patients with celiac disease, Down syndrome, and autoimmune diseases.
