Gastroenteritis: Almost always viral and should last -5 days. Drink extra fluids with and between meals, or try small amounts of water or suck on ice chips. Avoid fruit juices. They do not replace minerals and can actually increase diarrhea. Use sports drinks; Eat food in small amounts and let your stomach recover; Get lots of rest. You may feel tired or weak. If this does not help or you're dehydrated see a doc.
