If your child vomits so often that he or she cannot drink or vomits
every time he or she takes a drink, this is known as repeated vomiting. This
type of vomiting makes it impossible for a child to hold down any fluids or
solid food. The more episodes of vomiting that occur, the greater the chances
that your child will become
dehydrated. Your child has an even greater chance of
becoming dehydrated if he or she also has an illness that causes
diarrhea.
After your child vomits, wait 1 hour before giving him or her
something to drink, such as diluted fruit juice or an
oral
rehydration solution. If your child vomits after taking a drink, wait
about an hour before offering him or her more fluids.
A child who eats solid foods may have vomit that is the same color as
something he or she recently ate, such as peas or squash. However, vomit that
is green and clearly has not been colored by food may indicate a blockage in
the digestive tract, such as
pyloric stenosis or a
bowel obstruction. This is a medical emergency and
requires immediate evaluation.
