I am sweating alot, my stomach is running. everytime i eat or drink something i must immediately go to the toilet.

About diarrhea...: A simple tummy ache with symptoms like nausea, vomiting, or diarrhea, whether at home or traveling, may be from a virus infection, bacteria infection, or contaminated food. A normal person, not sickly or on medications, usually recovers fine. Taking a Pedialyte popsicle or 2-3 oz of Pedialyte hourly, plus drinking or eating little else, may settle things down. Otherwise, a Dr. should evaluate.
