What is Low blood sugar?

Low blood sugar is when your body doesn’t have enough fuel to keep you going strong.

Imagine your body is like a toy car that needs gas to run. When you eat food, it's like giving the car gas. The sugar in your blood is like that gas, it helps your brain and muscles work well. But sometimes, especially if you skip meals or do too much activity without eating, your body uses up all its sugar, and the toy car starts to slow down.

Your brain needs sugar to think clearly. If there's not enough, you might feel confused or even a little sleepy, like when you haven’t had breakfast and can’t focus in class.

You might also feel shaky or tired, like after jumping on the trampoline for too long without taking a break.

When your body is low on fuel, eating something sweet or having a snack helps it refuel. That’s like giving your toy car more gas so it can zoom again!

Sometimes people have low blood sugar because their bodies don’t make the right amount of hormones to control how much sugar stays in the blood, but that’s a story for when you’re a bit older!
