Fainting is a temporary loss of consciousness that happens when there isn't enough
blood going to the brain because of a drop in blood pressure. Blood pressure can drop
from dehydration, a
quick change in position, standing or sitting still for a long period, or a sudden
fear of something (such as the sight of blood).
It's important to get medical care to figure out what brought on the fainting episode
and help prevent it from happening again.
Whether your child is about to faint or already fainted: loosen tight clothing,
make sure the area is well-ventilated, wipe your child's face with a cool washcloth,
and don't let him or her stand or walk until feeling much better.
your child seems about to faint:
Have him or her lie down or sit down with the head between the knees.
If your child has fainted:
Have him or her lie flat with feet slightly elevated. Don't move your child if
you think the fall might have caused an injury.
Contact your child's doctor about any fainting episode.
