Know your numbers: blood sugar testing ranges explained.
You've learned how to stabilise your blood sugar. But how do you know if it's working? You test.
Here are the target ranges:
Fasting blood sugar (first thing in the morning): under 5.5 mmol/L. This is your baseline.
Post-meal blood sugar (2 hours after eating): under 7.8 mmol/L. This tells you how well your meal choices are working.
What do these numbers mean?
Under 5.5 mmol/L fasting = healthy, stable baseline.
5.5–7 mmol/L fasting = slightly elevated, worth optimising.
Above 7 mmol/L fasting = concerning, discuss with your GP.
Under 7.8 mmol/L post-meal = your meal was balanced and handled well.
7.8–11 mmol/L post-meal = moderate spike, adjust your meal or add movement.
Above 11 mmol/L post-meal = significant spike, rebalance your meal.
How to test:
Finger-prick meters are affordable and available at pharmacies. Takes 30 seconds.
Test at different times to understand your patterns:
- Fasting (first thing in the morning)
- 2 hours after breakfast, lunch, dinner
- Before bed
This gives you a complete picture of how your body responds to your habits.
Why test?
Testing isn't just for diabetics. If you're trying to stabilise energy, lose weight, or improve health, knowing your numbers is powerful. You see what works and what doesn't.
You might discover your "healthy" salad spikes your blood sugar. Or that a 10-minute walk cuts your spike in half. Data changes behaviour.
Ready to test? Grab a meter from your local pharmacy and test your fasting level tomorrow morning.
