If my wake-up blood sugar is below 100 does the rest of the day matter?
If you are diabetic that’s a good number to wake up to.
If you’re on insulin, try to keep your BS to under 200 at the highest, like right after a meal. It’s always a race between a meal and a bolus shot. Don’t fret the highs if your bolus can bring them down soon enough.
Fasting overnight 12 hours should fall between 70-100, a 125 is concerning after a 12 hour fast, During the day as you eat it should stay no higher than 125. Over 125 on 2 tests fasting is considered pre diabetic, over 200 on 2 tests fasting is diabetic.
