A fasting blood sugar level is a key indicator of your metabolic health, and understanding what it means can help you take control of your well-being. A fasting blood sugar level of 6.7 mmol/L (millimoles per liter) or 120 mg/dL (milligrams per deciliter) can be a cause for concern, as it may indicate issues with blood sugar regulation. Let’s break down what this number means and what steps you can take to address it.
1. Is 6.7 mmol/L High for a Fasting Reading?
Fasting blood sugar levels are measured after not eating for at least 8 hours, typically first thing in the morning. Here’s how to interpret a reading of 6.7 mmol/L:
Normal Range: A fasting blood sugar level between 4.0 to 5.4 mmol/L (70 to 99 mg/dL) is considered normal.
Prediabetes Range: A fasting level between 6.1 to 6.9 mmol/L (110 to 125 mg/dL) indicates prediabetes.
Diabetes Range: A fasting level of 7.0 mmol/L (126 mg/dL) or higher on two separate tests typically indicates diabetes.
What It Means: A fasting blood sugar level of 6.7 mmol/L is considered high and falls within the prediabetes range. This is a warning sign that your body isn’t processing sugar as efficiently as it should, and lifestyle changes may be needed to prevent progression to type 2 diabetes.
2. Why Are Fasting Blood Sugar Levels Important?
Fasting blood sugar levels provide insight into how well your body regulates glucose overnight.
Insulin Resistance: Your body isn’t using insulin effectively to lower blood sugar.
Dawn Phenomenon: A natural rise in hormones (like cortisol) in the early morning can increase blood sugar levels.
Poor Diet or Lifestyle Habits: Eating high-carb or sugary foods before bed can lead to elevated morning blood sugar.
3. Symptoms of High Fasting Blood Sugar
If your fasting blood sugar is consistently high, you may experience symptoms such as:
Fatigue or tiredness
Increased thirst
Frequent urination
Blurred vision
Slow-healing wounds
If you notice these symptoms alongside a high fasting blood sugar level, it’s important to seek medical advice.
4. What Should You Do?
If your fasting blood sugar level is 6.7 mmol/L, here are some steps to consider:
Consult Your Doctor: A single high reading isn’t enough to diagnose a condition, but it’s a red flag. Your doctor may recommend additional tests, such as an HbA1c or oral glucose tolerance test, to confirm your blood sugar status.
Monitor Regularly: Track your fasting blood sugar levels over time to identify patterns and understand how your body responds to food, exercise, and medication.
Adjust Your Diet: Focus on a balanced diet with complex carbohydrates, lean protein, and healthy fats. Avoid sugary or high-carb foods before bed.
Manage Stress and Sleep: Poor sleep and high stress levels can negatively impact blood sugar regulation.
5. Key Takeaways
A fasting blood sugar level of 6.7 mmol/L is considered high and may indicate prediabetes.
Morning blood sugar levels are influenced by factors like insulin resistance, diet, and hormonal changes.
Regular monitoring, lifestyle changes, and consultation with a healthcare professional are key to managing your blood sugar effectively.
