What Is a Stomach Infection in Children?
A stomach infection, also called gastroenteritis, is an infection of the stomach and intestines. It usually leads to symptoms like:
- Diarrhea (loose motions)

Stomach infections are very common in children because their immune system is still developing, and they often come in contact with germs through food, water, toys, or school environments.
