What, under 100 when waking? No, that’s good.
Right before waking, the human body adds sugar to the bloodstream to enable you to get up. This is called the dawn phenomenon.
I think anything between 80-120 is good.
I don’t get the “Pre-diabetes” designation. You either have diabetes or you don’t. The better number is fasting blood sugar. If your fasting BS is closer to 120 (or higher) then you may be a diabetic.
That’s why you should never do blood tests in the morning.
