Dyscatabrosis, Dyscataposia, Deglutitio difficilis, D. Ioesa, D. impedita, from 'with difficulty,' and 'I eat.' Difficulty of deglutition. Dysphagia is almost always symptomatic, either of inflammation or of other disease of the organs of deglutition, or of incomplete obstruction of the oesophagus, by some obstacle within it, or by a neighbouring tumour. At times, it is produced by spasms or paralysis of the oesophagus. The prognosis and treatment vary according to the cause.
