Diagnosis and Management of Gastroesophageal Reflux Disease (GERD)

Initial Assessment and Empirical Therapy

The American Gastroenterological Association recommends starting with an empirical trial of single-dose PPI therapy for 4-8 weeks in patients presenting with typical heartburn symptoms without alarm features 1, 2, 3
Screen for alarm symptoms that mandate immediate endoscopy rather than empirical therapy, including troublesome dysphagia, unintentional weight loss, evidence of gastrointestinal bleeding, persistent vomiting, and palpable mass or lymphadenopathy 2, 3, 6
Distinguish typical from atypical presentations, with typical symptoms including heartburn, acid regurgitation, and non-cardiac chest pain, and proceed with empirical PPI trial for typical symptoms 1, 3, 6

Perform endoscopy in scenarios including inadequate response to 4-8 weeks of twice-daily PPI therapy, presence of alarm symptoms, and need to confirm GERD diagnosis before committing to long-term PPI therapy 2, 3, 6, 7, 8
Complete endoscopic assessment must include erosive esophagitis grading, Barrett's esophagus assessment, hiatal hernia measurement, Hill grade of gastroesophageal flap valve, and evaluation for strictures or masses 1, 2, 5, 6
Ambulatory pH monitoring is preferred off PPI therapy, with diagnostic criteria including AET <4.0% on all days with normal endoscopy indicating no GERD, and AET ≥6.0% on ≥2 days or LA Grade B+ esophagitis indicating conclusive GERD 2, 6, 7, 8

For patients requiring chronic PPI therapy, evaluate appropriateness and dosing within 12 months of initiation, and consider reflux testing off PPI to establish need for lifelong therapy 2, 8
Provide standardized patient education on weight loss, head of bed elevation, avoiding recumbency after meals, and individualized trigger food avoidance 3, 5
