Blood glucose readings are not just cold numbers—they convey important health messages.
Fingerstick glucose meter readingIt reflects your real-time blood glucose level, like a “snapshot” of your blood sugar.It serves as direct guidance for your next meal, immediate exercise, and adjusting your current diabetes medication.For example:
A low reading before a meal means you need to eat right away.
A high reading 2 hours after a meal suggests you should adjust your diet or exercise at the next meal.
Glycated Hemoglobin (HbA1c)This indicator is like a “documentary” of your blood glucose control.It shows the percentage of hemoglobin in red blood cells that has bonded with glucose.Since red blood cells live about 120 days, HbA1c reliably reflects your average blood glucose over the past 2–3 months, and is not significantly affected by short-term changes in diet, exercise, or mood.It is the key indicator for evaluating whether long-term blood glucose control has reached the target.
