Gastroenteritis is a big, fancy word that means your tummy is feeling really sick. It's when the stomach and intestines get all inflamed and upset, making you feel pretty yucky.
You know how you feel when you get a really bad stomachache and can't stop pooping or throwing up? That's gastroenteritis. And it's usually caused by tiny germs called viruses, but sometimes bacteria or parasites can be to blame too.
These germs are really sneaky and can get into your body through the yucky things you put in your mouth or even from touching things that are dirty. That's why it's super important to always wash your hands before eating or touching your mouth or nose.
But don't worry, your tummy will start feeling better soon with lots of rest, drinking plenty of fluids like water, and eating easy-to-digest foods like bananas, toast, and rice. If your symptoms get really bad, your parents might need to take you to the doctor to get some special medicine to help you feel better.
