Gastroesophageal reflux in the adolescent.

Gastroesophageal reflux (GER) is relatively common in adolescence. The severity of gastrointestinal symptoms associated with gastroesophageal reflux varies from an occasional burp to persistent emesis. Evaluation of most of these patients reveals no definable anatomic, metabolic, infectious, or neurologic etiology. The clinical determination of a cause-and-effect relationship between GER and other disorders, including associated respiratory disease, is often difficult and must be approached with considerable caution. Tests that merely document the presence of GER add little to the diagnosis. The adolescent with GER often has persistent symptoms of esophagitis that lead to appropriate intervention. Understanding the capabilities and limitations of the various diagnostic maneuvers available to assess GER is important to avoid subjecting these patients to invasive, costly, and inappropriate testing. This article includes a general discussion of physiology, diagnostic evaluation, and therapy of GER, followed by a review of respiratory and other complications.
