Here's something that surprised me: the average adult body holds about 5 litres of blood, and the total amount of sugar circulating in it at any one time is only a teaspoon.
That tiny amount is why blood sugar regulation is such a big deal for your long-term health.
A single blood sugar reading only shows you one moment in time.
An HbA1c test is different as it reflects your average blood sugar over the past 2–3 months by measuring how much sugar has attached to your red blood cells. It's one of the best windows into your metabolic health.
The good news?
Daily habits move that needle. What you eat, how often you move, your sleep, your stress all add up.
If you've never had an HbA1c test, it might be worth a conversation with your doctor.
