Dysphagia should not be confused with the similarly pronounced
dysphasia, a language disorder. Dysphagia is a medical term defined as "difficulty swallowing." It derives from the Greek root dys meaning difficulty or disordered, and phagia meaning "to eat". It is a sensation that suggests difficulty in the passage of solids or liquids from the
mouth to the
stomach. Dysphagia is distinguished from similar symptoms including
odynophagia, which is defined as painful swallowing, and
globus, which is the sensation of a lump in the throat. A psychogenic dysphagia is known as
phagophobia.
