Illness

    Dehydration.

    Dehydration is common after viral illness, heat exposure, or reduced oral intake. Oral rehydration usually works; IV fluids help when you can't keep fluids down.

    Quick answer

    For dehydration from vomiting, diarrhea, heat exposure, or illness, we assess severity and give IV fluids when needed. Most patients feel better within an hour.
