Dysphagia usually manifests as a sensation of "stickiness" or difficulty in swallowing food. In upper oropharyngeal dysphagia, there is difficulty in initiating the act of swallowing, but once initiated, swallowing is completed normally. In esophageal dysphagia, the swallowed food may eventually navigate the esophagus or may be regurgitated or vomited if the obstruction is severe. Dysphagia is frequent in neurodegenerative disorders, such as Parkinson disease.
