Fasting blood sugar--when to take
Are you supposed to take a fasting blood sugar when you first wake up, or should it be right before you eat?
Mine is over 100 when I first wake up, but drops lower and lower the longer I go without eating. I'm not sure which reflects my "fasting blood sugar"--the number when I wake up, or the lowest point after that.

I test as soon as I get up in the morning and considered that my fasting BG. If it is a long time before I eat breakfast I will test again before I eat and dose accordingly. If I am high when I get up I will take a correction dose and then adjust accordingly when I do eat breakfast. I hope that made sense.

I take a fasting BS when I get up. If it is low, I will eat quicker. If yours is over 100 ( depends how much over 100) you can take your time to eat. You really shouldn't wait too long before eating breakfast. The fasting one is the first one you take after you get up in the morning. If the BS is a little high, take insulin (if you are a T-1)according to your I:C ratio, and add 1 or 2 units to correct the high.

Fasting is your waking BG, not your lowest or highest hours after waking. I check as soon as I wake up & eat soon after. When I delay breakfast, I test again before eating. My BG goes high if I wait too long to eat.
Hope you're recording your numbers to show to your doctor. Noticed on your page that you're LADA or prediabetic. Great that you're testing frequently!

I test as soon as I get up. My sugar starts rising fast within 40 minutes of my awakening whether I eat, exercise or not. I take a shot soon after my first test. Then shortly after, I will have a couple small/healthy items to eat plus a coffee.

Personally, I try to take it within an hour of waking, and for sure before I take my meds or eat anything. I have other responsibilities that have to be taken care of before I can take a reading accurately....and that's the way I do it. If I wait longer it's not a true fasting sugar in my mind, and I get too busy and forget that I haven't taken it.
