Esophagogastroduodenoscopy with possible biopsy is indicated in patients with persistent dyspepsia, if weight loss or symptoms suggest malabsorption, or if celiac disease is a concern. Colonoscopy is indicated for patients with warning signs, such as bleeding; anemia; chronic diarrhea; older age; history of colon polyps; cancer in the patient or first-degree relatives; or constitutional symptoms, such as weight loss or anorexia. A screening colonoscopy should be performed according to published guidelines.
