Gastroesophageal reflux: pathogenesis, diagnosis, and treatment.

Abstract

Gastroesophageal reflux (GER) is a common problem confronting physicians involved in the care of children and adults. With the association of GER with asthma and chronic cough, physicians specializing in allergy/immunology require information on the pathogenesis, diagnosis, and management of GER. Eosinophilic esophagitis or eosinophilic gastroenteritis are poorly understood entities that may also lead to symptoms mimicking GER and are associated in many cases with underlying hypersensitivity of unknown immunologic mechanism.
