• Choi KH

Abstract

Dysphagia is characterized by abnormality in the transfer of a bolus from the mouth to the stomach. It can occur as a result of a variety of structural injury and/or medical conditions including natural aging. Dysphagia may arise as comorbidities of other disorders or as precursors to more significant diseases and disorders. The prevalence of swallowing disorders may vary depending on the type of diagnostic evaluation. This article reviews the current epidemiologic data of dysphagia.
