Understanding Blood Sugar: What’s Normal and What’s Not

Content:
Blood sugar, also called blood glucose, is the body’s main source of energy. It comes from the food we eat, especially carbohydrates. The body regulates blood sugar with the help of insulin, a hormone produced by the pancreas.

• Normal fasting blood sugar: 70–99 mg/dL
• Prediabetes range: 100–125 mg/dL
• Diabetes range: 126 mg/dL or higher on two tests

Why balance matters:
Both high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) can harm the body. Over time, uncontrolled blood sugar can damage the heart, kidneys, nerves, and eyes.

👉 Monitoring blood sugar levels regularly is key to understanding your health and preventing complications.
