Upper Respiratory Tract Diseases as Extra Esophageal Manifestations of Gastroesophageal Reflux Disease: Current State of the Problem

Abstract

Bronchial asthma, chronic cough, laryngitis, erosion of tooth enamel are attributed to extra esophageal manifestations of gastroesophageal reflux disease (GERD).

At the same time, empirical therapy is most effective in patients whose extra esophageal symptoms are combined with typical ones
