Aziz Q, Fass R, Gyawali CP, Miwa H, Pandolfino JE, Zerbib F. Functional esophageal disorders. Gastroenterology. DOI: 10.1053/j.gastro.2016.02.012. PMID: 27144625. Functional heartburn requires burning retrosternal discomfort or pain, no relief despite optimal antisecretory therapy, no eosinophilic esophagitis, and no major esophageal motor disorder. Reflux evidence is elevated acid exposure, a positive symptom-reflux association, or both; either finding alone keeps the result at 0. Neither finding, together with no eosinophilic esophagitis, can meet the criterion. Criteria are fulfilled for the past 3 months, with onset at least 6 months earlier, at least twice a week. (2016)
