Editorial:Functional (Non-Ulcer) Dyspepsia and Gastroesophageal Reflux Disease: One Not Two Diseases?Talley, Nicholas J MD, PhD1American Journal of Gastroenterology: May 2013 - Volume 108 - Issue 5 - p 775–777 doi: 10.1038/ajg.2013.102 Stomach Buy Abstract Author InformationAuthors Article MetricsMetrics Functional dyspepsia is a very common, distressful, and costly condition. New data indicate that heartburn and regurgitation occur frequently in functional dyspepsia, even after objective gastroesophageal reflux disease has been exhaustively excluded by appropriate testing. Arbitrarily excluding heartburn in functional dyspepsia studies appears misguided. 1 University of Newcastle, Callaghan, New South Wales, Australia Correspondence: Nicholas J.
