Abstract
Gastroesophageal reflux (GER) refers to the passage of gastric contents (acid, pepsin, etc) in the esophagus. It is a worldwide physiologic condition most common in infants. This physiologic condition (GER) should be differentiated from the pathologic reflux called gastroesophageal reflux disease (GERD). The distinction between GER and GERD is based on severity of the reflux episodes.([1)(2])(,) The most common mechanism of reflux is transient lower esophageal sphincter relaxation (TLESR) and less commonly low resting LES pressure.([3])
GER presents with regurgitation and occasional vomiting only without effects on growth and development whereas GERD usually has additional presentations. The objective of this review is to provide update on recent developments in the diagnosis and management of this condition.
