Diarrhea, Vomiting, and Water Loss (Dehydration)

View spanish version, share, or print this article.

Diarrhea (loose poop) and
vomiting, or “throwing up,” are why many parents call the doctor.
Your child’s doctor may call this gastroenteritis (GAS-
troh-en-tur-EYE-tis). These symptoms are often caused by a

Your child may first have a fever and some vomiting.
Diarrhea often starts later. The symptoms usually go away in a day or two. But
they can last a week before getting better.

One danger with diarrhea and vomiting is that your
child’s body can get dried out or dehydrated (dee-hye-DRAY-dud). This
happens when the body loses too much water.

Call the Doctor If…

…your child has diarrhea, vomiting, and is
younger than 6 months or your child has:

  • A fever over 102°F or

  • Blood in the stool (poop) or vomit.

  • Green vomit.

  • Vomiting for more than 12 hours or diarrhea
    for more than 2 days.

  • Belly pain.

Also Call the Doctor If…

. ..your child has any of these signs of being too

  • Pees very little (wets fewer than 6 diapers
    per day)

  • Has no tears when crying

  • Can’t or won’t drink anything
    or feels very thirsty

  • Has a dry, sticky mouth, or dry lips

  • Looks like he or she has lost weight

  • Has sunken eyes or sunken soft spot on head
    (for babies)

  • Acts very tired or strange

Most of the time you can treat this by getting your
child to drink something and eat simple foods.

(See the list below.)

But your child may need a special fluid that you can
buy in a store. It’s called an electrolyte drink*. If your child
can’t drink this, then he or she may need to go to the hospital.

Call your child’s doctor if vomiting or
diarrhea won’t go away. The doctor may want to check your child.

What to Do for Vomiting

  • Give small sips of clear fluids every 10 to
    15 minutes.

  • If your child keeps vomiting but is NOT dry,
    wait 1 to 2 hours before trying again. Stop if your child starts to
    throw up again, and call the doctor.

    wants to eat, try giving small amounts of simple foods. See the chart on

What to Do for Diarrhea

Most diarrhea lasts 3 to 6 days or even longer.
Don’t worry as long as your child acts well and is eating and drinking
and peeing like usual.

Mild Illness

Most children should keep eating normal foods
when they have mild diarrhea.

The doctor may suggest changing what your child
eats for a few days. This might mean stopping cow’s milk, but
breastfeeding your baby is fine.

Moderate Illness

Children with moderate diarrhea can be cared for
at home.

  • They need special fluids, like
    electrolyte drinks. Talk with the doctor about how much and how long
    to give these and which to buy.

  • Some children can’t handle
    cow’s milk when they have diarrhea. They may need to stop
    drinking it for a few days. Breastfeeding is fine for babies.

  • As your child gets better, he or she can
    go back to normal foods.

Severe (Very Bad) Illness

See the “Call the Doctor If” list.
Call the doctor right away if your child shows any of those warning signs.
You may need to take your child to the emergency room for treatment.
