Hi. I'm a 17-year-old female with a healthy weight for my age and height, but I'm not that active and rather sedentary and I honestly don't eat that well either. Both of my parents are T2 diabetics and as far as I know, I'm not diabetic. I use their blood sugar meter as they don't use it (they're not fussed with checking their blood, and when they do, it's normal) and we have gotten more strips after a month of not having them, so I decided to check my blood sugar. Yesterday, 2-hours post-meal, it was 6.2, which I believe is normal for a non-diabetic. But this morning after 10+ hours of not eating my blood sugar was 5.4 (apparently, 5.5 is the cut-off for within normal range?) so I decided to check once more to be sure and it read 5.7 which worried me. So, I washed my hands in warm water and checked several times again on different fingers and different hands squeezing only very lightly, and I got 4.8, 5.5, 5.0, and 5.2. I'm not asking anyone to try and diagnose me, just looking for some advice, really. Would you say my blood sugar readings are normal for a non-diabetic? All readings aside from the 5.7 and 5.5 are normal from what I know. Am I pre-diabetic? Borderline pre-diabetic? Do non-diabetics blood fluctuate, as well? Would stress affect my readings? (while I'm not a diagnosed diabetic, I'm diagnosed with general anxiety and am admittedly a hypochondriac) To be fair, the last thing I ate last night was chocolate (around 8 PM) and I went to sleep at around 11 PM and checked my blood at 7 AM) so could it be because of that? I've had some breakfast and I'm going to check again 2 hours after, and I'm waiting 8 hours before I eat again to check once more. I would really appreciate some advice.
