Functional (Nonulcer) Dyspepsia T2 CURRENT Diagnosis & Treatment: Gastroenterology, Hepatology, & Endoscopy, 2e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-176848-1 LK accessmedicine.mhmedical.com/content.aspx?aid=55957186 RD 2024/04/19 AB Dyspepsia is a common symptom having either an organic or a functional cause; distinguishing between the two can be a challenge.Clinical features of functional dyspepsia, gastroesophageal reflux disease, and gastrointestinal motility disorders overlap, making diagnosis difficult.Most patients with functional dyspepsia have normal esophagogastroduodenoscopy (EGD) findings.Endoscopy is indicated for patients with new-onset symptoms who are >55 years of age or have alarm features.Functional dyspepsia remains a diagnosis of exclusion.
