Overview

There is no established system for the classification of [disease name].

Classification

Classification based on etiology

• Acute diarrhea may be classified according to etiology into infectious and non-infectious subtypes/groups. The infectious group may further be classified into bacterial, viral, fungal and protozoal subgroups. The non-infectious group is further classified into diarrhea due to medications, poisoning and systemic illnesses.

Classification based on presentation

• Based on the type of presentation, acute diarrhea may be classified into watery and inflammatory types. Watery diarrhea may further be classified into secretory and osmotic types of diarrhea.
