Diarrhea is a problem with your intestines. You might get it if you eat food that is bad or drink something that contains bacteria, but people usually get it from diseases caused by a virus. Diarrhea gives you pain in your belly and sometimes makes you run to the bathroom! In the bathroom, waste that is full of liquid leaves your body very quickly. The process stops for while but usually returns. Ordinary diarrhea doesn't usually last more than a few hours, but diarrhea can be serious if people have it for a few days or longer because their bodies lose too much water. |
