Gastroenteritis is a common childhood illness that causes diarrhea and vomiting that can lead to dehydration. It is usually caused by a virus but can also be caused by bacteria or a parasite. Most of the time mild diarrhea and vomiting last for just a few days. However, if symptoms don't go away or they get worse, your child may need to be treated in the hospital.
Call your child's doctor if your child is younger than 6 months and has any of the following:
Blood in the stool
Urinates less often (Wets fewer than 6 diapers per day.)
No tears when crying
Loss of appetite for liquids
High fever (over 102°F or 39°C)
Dry, sticky mouth
The biggest concern with gastroenteritis is dehydration, which occurs when a child loses too much fluid and becomes dried out. If your child has lost a lot of fluids from vomiting or diarrhea, he may need an IV to get fluids back into his body. An IV is a small plastic tube that is placed inside a vein under your child's skin. Fluids are given through the IV.
Once your child gets fluids into her body and starts making normal amounts of urine again, she will be able to go home. This can take only a few hours, or your child may need to stay overnight in the hospital.
For cases of mild to moderate diarrhea, continue to give your child a normal diet including formula or milk. Breastfeeding can continue. If your child is not able to tolerate cow's milk because of the diarrhea, talk with your child's doctor about temporarily removing it from his diet.
Special fluids called electrolyte solutions have been designed to replace water and salts lost during diarrhea. Do not try to prepare these special fluids yourself. Ask your child's doctor or a pharmacist for a recommendation.
Continue to feed your child if he is not vomiting. You may have to give your child smaller amounts of food than normal or give your child foods that do not further upset his stomach.
The following are ways to keep your child healthy:
Stop germs from spreading. Frequent hand washing with soap or using a hand sanitizer is the best way to prevent these germs from spreading.
Avoid germs. Try to keep your child away from children who have diarrhea or are vomiting.
