Overview
Dysphagia is classified according to location into two subtypes/groups:
- Oropharyngeal dysphagia
- Esophageal dysphagia
Dysphagia may be classified into several subtypes based on etiology into six subclasses: Infectious, Metabolic, Myopathic, Neurological, Structural and, Iatrogenic
Classification of Dysphagia
Dysphagia is classified into two major types on the basis of location:
- Oropharyngeal dysphagia
- Esophageal dysphagia
It is also classified on the basis of etiology into six subclasses:
- Infectious
- Metabolic
- Myopathic
- Neurological
- Structural
- Iatrogenic
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.
