Deglutition disorder

Short Description or Definition

Dysphagia is a disorder in the preparation and/or transportation of food and/or liquid from the lips to the duodenum.


Dysphagia is divided into several types, dependent on etiology and locus of symptomatology. In general, categories can be oral, oral-pharyngeal, pharyngeal, esophageal, and/or gastric.


Over a lifetime, 1 in 17 people will develop a swallowing problem or dysphagia. In a 2011 study in the United Kingdom, the prevalence rate in the general community was 11%. The condition affects 40–70% of people with stroke. Patients with neurodegenerative diseases have a 60–80% incidence of dysphagia. In adults 65 and older, 11% may experience dysphagia, often related to gastric reflux. In the institutionalized elderly, the percentage rises to 51%. For patients who have experienced radiation treatments to the head and neck, the incidence of dysphagia is 60–75%.
