Dysphagia is classified according to location into two subtypes/groups:
Dysphagia may be classified based on the location into oropharyngeal dysphagia or esophageal dysphagia. Dysphagia may also be classified based on etiology into further six subclasses which include infectious, metabolic, myopathic, neurological, structural and, iatrogenic.
* Oropharyngeal dysphagia
 
* Esophageal dysphagia
Dysphagia may be classified into several subtypes based on etiology into six subclasses: Infectious, Metabolic, Myopathic, Neurological, Structural and, Iatrogenic

===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.
* Arises from the body of the [[esophagus]], [[lower esophageal sphincter]], or [[Stomach|cardia of the stomach]].  
* Most commonly esophageal dysphagia is either due to mechanical obstruction of esophageal lumen or motility problems.


In some patients, no organic cause for dysphagia can be found, and these patients are defined as having functional dysphagia.
=== Functional dysphagia ===
* Dysphagia due to no organic cause.
* Diagnosis of exclusion.

Overview

Dysphagia may be classified based on the location into oropharyngeal dysphagia or esophageal dysphagia. Dysphagia may also be classified based on etiology into further six subclasses which include infectious, metabolic, myopathic, neurological, structural and, iatrogenic.

Classification of Dysphagia

Dysphagia may be classified based on the location into two major types:[1][2][3]

Dysphagia can also be classified based on the etiology into six sub classes:

Oropharyngeal Dysphagia

Esophageal Dysphagia

Functional dysphagia

  • Dysphagia due to no organic cause.
  • Diagnosis of exclusion.
