Your A1C is an average of your blood sugar over about three months. Daily numbers are the day-to-day readings you see from finger checks or a CGM.
Why?
Because averages don’t tell the whole story. You can have a “good” A1C and still experience big highs and lows—or a higher A1C while actively improving your daily patterns.
The Catch?
A1C doesn’t show variability, timing, or how often you spike. Daily numbers can feel emotional and noisy if you don’t zoom out and look for trends.
The Takeaway
A1C is the long view. Daily numbers are the steering wheel. You need both to understand what’s really going on.
One shows the journey. The other shows the turns.
→ You need both.
