The term "blood sugar" is common, but what does it actually mean for your body and well-being? Understanding blood sugar, also known as glucose, is the first step towards taking control of your metabolic health, whether you have diabetes or are simply health-conscious.
What is Glucose?
Glucose is a simple sugar that serves as the primary source of energy for your body's cells. Think of it as the fuel that powers everything you do, from moving and thinking to simply breathing. When you eat carbohydrates (like bread, pasta, or fruit), your digestive system breaks them down into glucose. This glucose then enters your bloodstream, ready to be delivered to your cells.
The Role of Insulin: The Key to Your Cells
For glucose to enter your cells and be used for energy, it needs a "key." That key is a hormone called insulin, produced by your pancreas. In a healthy system:
- You eat, and your blood glucose rises.
- Your pancreas releases insulin into the bloodstream.
- Insulin "unlocks" your cells, allowing glucose to enter and provide energy.
- Your blood sugar levels return to a normal range.
What Are Normal Blood Sugar Levels?
Maintaining stable glucose levels is crucial. According to international guidelines, widely accepted across Europe, target levels for people without diabetes are generally:
- Fasting (before meals): 4.0 - 5.5 mmol/L (72 - 99 mg/dL)
- After meals (1-2 hours after eating): Less than 7.8 mmol/L (140 mg/dL)

Why Balancing Your Blood Sugar Matters
When this system works smoothly, you have steady energy levels. However, if it becomes disrupted, it can lead to:
- Hyperglycemia (High Blood Sugar): Occurs when there isn't enough insulin or when your body can't use insulin effectively. This is a hallmark of diabetes.
- Hypoglycemia (Low Blood Sugar): Occurs when blood sugar drops too low, potentially causing shakiness, sweating, and confusion.
The First Step Towards Better Health
Understanding glucose is the foundation. For individuals with diabetes or prediabetes, monitoring these levels becomes essential to manage the condition effectively and prevent complications.
