Stomach infection (gastroenteritis)

Skip Navigation

Top of the page

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 the flu.

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.
