A member asked:

Is there any certain causative agent that makes one have diarrhea and throwing up at the same time? or is it just some stomach bug/virus?

A doctor has provided 1 answer

Gastroenteritis: There are many causes for this, some due to virus, some to ingested toxic material, some to bacteria, etc. The nature of the offending agent will help to determine whether you get both vomiting and diarrhea or only one of them. Usually this is viral, but as stated above may be of many sources.
