Diarrhea is a loose, watery bowel movement and is not usually a serious problem in the U.S. It can occur due to illness, intestinal problems, food poisoning, and many others factors. It usually goes away on its own, but you should drink plenty of fluids and can take over-the-counter medications to help ease the discomfort. For prolonged cases of diarrhea, medical attention is recommended. Follow the links below to find WebMD's comprehensive coverage about how diarrhea is contracted, how to treat it, and much more.
