Dysphagia, Swallowing Disorders, and Cough.

This article explores the relationship between cough and dysphagia. Both are nonspecific symptoms that arise from a variety of heterogenous and frequently multifactorial etiologies. We specifically examine the physiology of cough in relation to swallowing and summarize pertinent existing literature in disorders and diseases of aspiration, cervical diverticula, esophageal motility, eosinophilic esophagitis, and age-related changes in swallowing physiology. Treatment options for specific swallowing disorders that can result in cough are discussed, although robust data for cough outcomes are limited in the existing literature.
