Gastroesophageal reflux disease (GERD) is the most common gastrointestinal diagnosis made in outpatient clinics, responsible for over 5 million annual outpatient visits and likely hundreds of thousands of inpatient stays for noncardiac chest pain. GERD’s current definition, based on international consensus, is a “condition which develops when the reflux of stomach contents causes troublesome symptoms (i.e., at least two heartburn episodes per week) and/or complications.” Also defining GERD is the presence of erosive esophagitis on upper endoscopy (esophagogastroduodenoscopy [EGD]) with or without the presence of troublesome symptoms or the presence of troublesome symptoms without endoscopic evidence of erosive esophagitis (also known as nonerosive reflux disease). This review looks at GERD in detail, including its epidemiology and risk factors, genetics, pathogenesis and etiologic factors, clinical presentation and symptoms, differentials, diagnosis, and complications. Figures presented are an EGD image showing signs of erosive esophagitis, Barrett esophagus, and hiatal hernia and sample recordings from a 24-hour combined multichannel intraluminal impedance and pH testing. Tables list differential diagnoses for GERD, indications for performing EGD in patients with GERD symptoms, and a summary of GERD therapies. This review contains 2 figures, 4 tables, and 74 references. |
