Overview
Classification
Dysphagia is classified into two major types: oropharyngeal dysphagia (or transfer dysphagia) and esophageal dysphagia.
Oropharyngeal dysphagia
Arises from abnormalities of the upper esophagus, pharynx, and oral cavity.
Esophageal dysphagia
Arises from the body of the esophagus, lower esophageal sphincter, or cardia of the stomach. Usually due to mechanical causes or motility problems.
In some patients, no organic cause for dysphagia can be found, and these patients are defined as having functional dysphagia.
