Dysphagia is difficulty in swallowing.[1][2] Although classified under "symptoms and signs" in ICD-10,[3] in some contexts it is classified as a condition in its own right.[4][5][6]
It may be a sensation that suggests difficulty in the passage of solids or liquids from the mouth to the stomach,[7] a lack of pharyngeal sensation or various other inadequacies of the swallowing mechanism. Dysphagia is distinguished from other symptoms including odynophagia, which is defined as painful swallowing,[8] and globus, which is the sensation of a lump in the throat. A person can have dysphagia without odynophagia (dysfunction without pain), odynophagia without dysphagia (pain without dysfunction) or both together. A psychogenic dysphagia is known as phagophobia.[9]
