Blood Sugar Basics
Understanding this is the key to preventing diabetes.
💡 Blood sugar (glucose) is your body’s main source of energy — but too much over time causes damage.
What is Blood Sugar?
Blood sugar (glucose) comes from the food you eat — especially carbohydrates like bread, rice, pasta, and sugary foods.
After eating, your blood sugar rises. Your body uses a hormone called insulin to bring it back down.
What Goes Wrong in Pre-Diabetes?
In pre-diabetes, your body starts to struggle to control blood sugar properly.
- Insulin doesn’t work as well (insulin resistance)
- Blood sugar stays higher for longer
- This slowly damages blood vessels and organs
Think of It Like This
🧠 Imagine your blood as a road and sugar as traffic.
- Normal → traffic flows smoothly
- Pre-diabetes → traffic builds up
- Diabetes → traffic jam all the time
Healthy vs High Blood Sugar
🟢 Green = Healthy range 🟡 Yellow = Pre-diabetes 🔴 Red = Diabetes range
📊 What this means:
You don’t need extreme changes — just enough to move from the yellow zone back into the green.
Why This Matters
Even slightly raised blood sugar over time can increase your risk of:
- Type 2 diabetes
- Heart disease
- Stroke
⚠️ The good news: pre-diabetes can often be reversed.
