Dysphagia : Introduction
Dysphagia difficulty with swallowing refers to problems with the transit of food or liquid from the mouth to the hypopharynx or through the esophagus.( Dysphagia is defined as difficulty in swallowing.) Severe dysphagia can compromise nutrition, cause aspiration, and reduce quality of life.
Pertaining to swallowing dysfunction is as follows.
Aphagia denotes complete esophageal obstruction, most commonly encountered in the acute setting of a food bolus or foreign body impaction.
Odynophagia refers to painful swallowing, typically resulting from mucosal ulceration within the oropharynx or esophagus. It commonly is accompanied by dysphagia, but the converse is not true.
Globus pharyngeus is a foreign body sensation localized in the neck that does not interfere with swallowing and sometimes is relieved by swallowing.
Transfer dysphagia frequently results in nasal regurgitation and pulmonary aspiration during swallowing and is characteristic of oropharyngeal dysphagia.
Phagophobia (fear of swallowing) and refusal to swallow may be psychogenic or related to anticipatory anxiety about food bolus obstruction, odynophagia, or aspiration. ]]>
