Definition: Dysphagia refers either to the difficulty someone may have with the initial phases of a swallow (usually described as “oropharyngeal dysphagia”) or to the sensation that foods and or liquids are somehow being obstructed in their passage from the mouth to the stomach (usually described as “esophageal dysphagia”). Dysphagia is thus the perception that there is an impediment to the normal passage of swallowed material.
