title: Gastroesophageal reflux: practical management of a common, challenging disorder.
abstract: Gastroesophageal reflux (GER) occurs in 2 distinct forms that differ in pathophysiology, clinical presentation, natural history, and therapy: mild GER (with no or minimal esophagitis) and classic, severe reflux (at risk for erosive esophagitis). A minority of subjects (< 20%) have the classic, potentially severe pattern of GER caused by reduced lower esophageal sphincter (LES) pressure and prolonged acid reflux, particularly at night, but also during the day. Evaluation and management must be catered to patients with this pattern of reflux. In contrast, symptoms in mild reflux (the majority) often occur during the day after meals in an upright posture (upright reflux); resting LES pressure is usually normal (reflux episodes are related to transient relaxation of the LES) and little reflux occurs at night. Acid reflux, which occurs mostly during the day, overlaps with the normal range and esophagitis is rare; however, symptoms can be distressing. Optimal management is controversial because no outcome trials have been conducted to address management in primary care settings. However, clinical clues can help differentiate mild and severe reflux and guide management decisions. This article provides a detailed approach to current management of GER syndromes.
