Gastroenteritis Overview
Gastroenteritis is a condition that causes irritation and inflammation of the stomach and intestines (the gastrointestinal tract). Diarrhea, crampy abdominal pain, nausea, and vomiting are the most common symptoms.

Many people who experience the vomiting and diarrhea that develop from these types of infections or irritations think they have "food poisoning," and they may indeed have a food-borne illness. Many people also refer to gastroenteritis as "stomach flu," although influenza has nothing to do with the condition.
