Nobody likes diarrhea. Diarrhea by itself is a whole other deal than the stomach bug where you get nausea, vomiting, and diarrhea. When you just have diarrhea, that can come from several different causes. It can be a virus, it can be a bacteria, it can be a parasite, you usually know that because the stool and the gas is very foul-smelling. It can be things like an irritable bowel syndrome or certain foods that your body doesn't react well to. Now, diarrhea is usually short-lived and it goes away pretty easily. You can treat it by avoiding dairy products because that tends to promote diarrhea. Going on a clear liquid diet for about six or eight hours, that's anything you can see through by Coke, Water, Gatorade, T7a, Gingerale, that kind of thing. Now the warning signals for when diarrhea is something bad and you need to get some help is if there's blood or pus in the stool, if you have a lot of pain, if you have a significant fever or anything over a hundred, that's a bad sign. Or if you have diarrhea and have recently traveled. The traveling diarrhea and travelers diarrhea from going to third world countries can be bad. You just don't know if it's a virus, a bacteria, or a parasite, but your physician should be able to help you.
