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.

Care At the Hospital
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, they may need to get fluids back into their body. One way to do this is through a small plastic tube called an IV. The IV is placed inside a vein under your child's skin. Another way is to pass a thin tube from the nose into the stomach and administer fluids directly into the GI tract.
Once your child gets fluids into their body and starts making normal amounts of urine again, they will be able to go home. This can take only a few hours, or your child may need to stay overnight in the hospital.
Care At Home
For cases of mild to moderate diarrhea, continue to give your child their regular diet. Continue to give breast milk, baby formula or both. 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 their diet.
