The stomach flu (gastroenteritis) is a nonspecific term for various inflammatory problems in the gastrointestinal (GI) tract.

Food allergies may produce eosinophilic gastroenteritis, a sign of which is increased eosinophils (a type of white blood cell) seen in the blood. Children with the stomach flu or gastroenteritis have similar symptoms to adults, but also may have symptoms such as refusing to drink or being very thirsty.

The main way contagious causes of the stomach flu are spread is person to person via the fecal-oral route. Individuals at most risk of catching the stomach flu are those in close association with an infant, child, or an adult that has a viral or bacterial cause of stomach flu .

Stomach flu is diagnosed in most cases without specific tests, however, tests can help define the underlying cause. Home remedies may reduce symptoms of stomach flu, including diet changes. Most people with viral or mild bacterial gastroenteritis require no treatment. Some individuals may require symptom reduction with medications but more serious bacterial infections may require antibiotic therapy.
