GI

    Stomach virus (gastroenteritis).

    Most gastroenteritis is viral and self-limited. Bacterial or parasitic infections may need testing and antibiotics.

    Quick answer

    Viral gastroenteritis (stomach flu) causes nausea, vomiting, and diarrhea, usually resolving in 1–3 days. We provide anti-nausea medication and IV fluids when dehydration is a concern.
