What Causes Diarrhea?

Learn what causes diarrhea from gastroenterologist Lisa Ganjhu, M.D. in this Howcast video about stomach problems and digestive disorders.


Okay, so you can have either acute diarrhea or chronic diarrhea. Basically, acute diarrhea is something that a lot of people can have intermittently, if they've eaten out, if they've gotten food poisoning, or they've traveled somewhere. Usually those are short lived and gets out of your system in a couple of days.

Now, chronic diarrhea, on the other hand means it happens every day and you're multitude of bowel movements, and that happens in patients that have something called colitis, ulcerative colitis, Chron's disease, or inflammatory bowel disease and also in some people that have irritable bowel syndrome. So anytime you have lots of diarrhea for a long period of time, that's called chronic diarrhea. So chronic diarrhea is associated with something called colitis which is inflammation of the colon and there's a lot of different types of colitis.

There is inflammatory bowel disease which is more like an ulcerative type disease such as Chron's disease or ulcerative colitis. Then you can have colitis that's non-bloody and that's basically like lymphocytic colitis, or congeal colitis. Then you can have infectious colitis that's for like either c-dif or E-coli or salmonella, or shodella. Things that you may pick up from eating out. Now those types of diarrhea are more likely to cause acute diarrhea as opposed to chronic diarrhea.
