<Tr> <Td_colspan="2"> (edit on Wikidata) </Td> </Tr> <P> Dysphagia is the medical term for the symptom of difficulty in swallowing . Although classified under "symptoms and signs" in ICD - 10, the term is sometimes used as a condition in its own right . People with dysphagia are sometimes unaware of having it . </P> <P> It may be a sensation that suggests difficulty in the passage of solids or liquids from the mouth to the stomach, 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, 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 . </P> <P> Some patients have limited awareness of their dysphagia, so lack of the symptom does not exclude an underlying disease . When dysphagia goes undiagnosed or untreated, patients are at a high risk of pulmonary aspiration and subsequent aspiration pneumonia secondary to food or liquids going the wrong way into the lungs . Some people present with "silent aspiration" and do not cough or show outward signs of aspiration . Undiagnosed dysphagia can also result in dehydration, malnutrition, and renal failure . </P>
