Stomach Flu (Gastroenteritis) Stomach flu, sometimes called
gastroenteritis, is inflammation of the stomach and intestines.
It can be caused by a viral, bacterial, or a parasitic
infection. 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. eMedicineHealth Medical Reference from Healthwise
