Your Body's Energy Currency
Your Body's Energy Currency
Glucose is the primary sugar that circulates in your bloodstream, providing energy to every cell in your body like fuel flowing through your internal distribution system. Your pancreas produces insulin to help cells absorb glucose from the blood, maintaining stable levels throughout the day. When this balance is disrupted, either through insufficient insulin production or poor insulin function, glucose levels can become too high or occasionally too low.
Glucose serves as your body's preferred energy source, working as your internal power supply—when glucose levels are balanced, your body functions smoothly, but when they're disrupted, it can affect everything from your daily energy to your long-term health.

When Glucose Levels Are Out of Balance
When Glucose Levels Are Normal: Normal glucose levels indicate that your body is effectively managing blood sugar through proper insulin function. Your liver stores excess glucose and releases it when needed, whilst your pancreas produces the right amount of insulin in response to blood sugar changes.
At healthy levels, glucose provides steady energy for your brain, muscles, and cells throughout your body without the damaging effects of prolonged high blood sugar.
When Glucose Becomes Too High: High glucose levels occur when your body either doesn't produce enough insulin or becomes resistant to insulin's effects. Over time, elevated glucose damages blood vessels, nerves, and organs throughout your body.
High glucose often develops gradually without noticeable symptoms initially. You might experience increased thirst, frequent urination, fatigue, or blurred vision, but these signs are often dismissed as stress or aging.
When Glucose Becomes Too Low: Low glucose levels can occur due to prolonged fasting, excessive alcohol consumption, certain medications, or underlying medical conditions, though it's less common in people without diabetes.
Symptoms include shakiness, sweating, confusion, irritability, and rapid heartbeat. In severe cases, loss of consciousness can occur. Unlike high glucose, these symptoms appear quickly and require immediate attention.

What Influences Your Glucose Levels
What Drives Glucose Higher: Several factors can overwhelm your body's glucose management system. Type 2 diabetes and pre-diabetes directly challenge your blood sugar control, whilst excess weight around your waist makes cells less responsive to insulin. Sedentary lifestyles, diets high in refined carbohydrates, chronic stress, certain medications like steroids, and genetic predisposition all work against your natural glucose regulation.
You may be at higher risk for elevated glucose if you have a family history of diabetes, are overweight (particularly around the waist), lead a sedentary lifestyle, or belong to certain ethnic groups including South Asian, African Caribbean, and Middle Eastern populations who have higher genetic predisposition to diabetes.
What Supports Healthy Glucose: Your body's glucose control thrives when you support it through regular physical activity, which helps muscles absorb blood sugar efficiently. Maintaining a healthy weight, choosing whole grains and vegetables over refined carbohydrates, managing stress, getting adequate sleep, and limiting alcohol all work together to keep your blood sugar stable and your energy systems functioning smoothly.

Managing Your Glucose Levels
For high glucose: Treatment depends on the underlying cause and severity. This includes adopting a balanced diet with controlled carbohydrate intake, emphasising whole grains, vegetables, lean proteins, and healthy fats, limiting refined sugars and processed foods, maintaining regular meal timing, and monitoring portion sizes.
Regular physical activity (at least 150 minutes of moderate exercise weekly), maintaining healthy weight through balanced nutrition, ensuring adequate sleep, and limiting alcohol consumption are essential. Your doctor may recommend medication such as metformin or other diabetes medications if lifestyle changes aren't sufficient.
For low glucose: Treatment focuses on identifying and addressing the underlying cause, which may include adjusting medications, modifying eating patterns, or managing underlying medical conditions.

Understanding Your Results
Fasting glucose levels are measured in millimoles per litre (mmol/L) and provide crucial information about your blood sugar management:
Low: Below 4.0 mmol/L
Normal: 4.0-5.6 mmol/L
High (prediabetes range): 5.61-6.99 mmol/L
Very high (diabetes range): 7.0 mmol/L and above
These ranges help determine whether your glucose regulation system is working effectively or showing signs that could progress to more serious problems without intervention.
Fasting glucose should be evaluated alongside other tests like HbA1c (a marker of blood sugar control over 2-3 months) for a complete assessment of glucose control and diabetes risk.

The Takeaway
Glucose levels provide crucial information about your body's ability to manage blood sugar and your risk of developing diabetes. High levels significantly increase your risk of serious health complications, particularly in people with additional risk factors such as family history, excess weight, or sedentary lifestyle.
Most people can improve their glucose control through lifestyle changes—healthy eating, regular exercise, weight management, and stress reduction. Some individuals with genetic predisposition or established diabetes may need medication alongside lifestyle modifications.
If you experience symptoms like excessive thirst, frequent urination, or unexplained fatigue, a blood test can determine whether your glucose levels are within the normal range and guide appropriate treatment if needed.
