Stomach flu, sometimes called gastroenteritis, is inflammation of
the stomach and intestines. It can be caused by a viral, bacterial, or a
parasitic infection.
The symptoms of gastroenteritis include nausea, vomiting, abdominal
cramps, diarrhea, fever, and weight loss.
Stomach flu usually goes away without medical treatment in 1 to 2
days. Home treatment can relieve the symptoms of stomach flu and prevent
problems, such as dehydration.
