Home > Health Library > Stomach infection (gastroenteritis)
A stomach infection, sometimes called gastroenteritis, can be caused by a viral, bacterial, or a parasitic infection, but it is not caused by the influenza virus.
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.
