Distinct causes of diarrhea can be a virus such as a rotavirus, hepatitis, a bacterium such as E.coli, Shigella, and parasites causing amoebiasis and giardiasis. Majority of the events of diarrhea are recognized to be concluded with simple dietary modifications and may not require treatment, however, in certain cases of severe diarrhea, laboratory assessment is requisite which includes blood tests, and stool specimen evaluation to analyze the type of diarrhea.
