What is blood sugar?
Blood sugar, or glucose, is the sugar in your blood. Your body uses glucose for energy to run your brain, muscles, and organs.
Where does it come from?
- Food, especially carbohydrates like bread, fruit, and pasta, which your body breaks down into glucose.
- The liver can release glucose when you need a quick boost of energy.
How does it travel and get used?
After you eat, glucose goes into your bloodstream. Your pancreas makes a hormone called insulin, which helps glucose move from the blood into your body's cells to use as energy.
Why does keeping it in a good range matter?
If blood sugar stays too high or too low, you might feel unwell. Most people stay within a steady range most of the time by eating balanced meals and staying active.
What can affect your blood sugar?
- Eating meals and snacks with carbohydrates
- Physical activity, like playing, running, or gym class
- Skipping meals or not eating enough
Tips to keep it balanced
- Eat meals with fiber (like fruits, veggies, and whole grains), protein, and healthy fats
- Choose water or milk instead of sugary drinks
- Move your body every day
- Get good sleep
If you notice unusual thirst, tiredness, or a big change in how you feel, tell a grown-up. They can help you check and explain what it means.
