stomach infection (gastroenteritis)

a stomach infection, sometimes called gastroenteritis, can be caused by a viral, bacterial, or parasitic infection. it is sometimes called "stomach flu," but it is not influenza.

the symptoms of gastroenteritis include nausea, vomiting, abdominal (belly) cramps, diarrhea, fever, and weight loss.

a stomach infection usually goes away without medical treatment in 1 to 2 days. home treatment can relieve the symptoms of a stomach infection and prevent problems, such as dehydration.
