Prevent Dehydration
Drink plenty of liquids to replace fluids that are lost from throwing up and diarrhea.
Sports drinks and other drinks without caffeine or alcohol can help with mild dehydration. But, these drinks may not replace important nutrients and minerals. Oral rehydration fluids that you can get over the counter are most helpful for mild dehydration.
If you think you or someone you are caring for is severely dehydrated, call a doctor.
