How to treat diarrhea?

Doctor can evaluate: Loose stools can be from variety of causes. People usually see their doctors if symptoms are bad or if they last more than 1-2 days. When diarrhea first starts happening, a person can benefit by stopping oral intake for a few hours, and then start just drinking small amounts (few ounces) of something like Pedialyte or half-strength Gatorade each hour. That should decrease the amount of diarrhea.
