Good morning all,
@Flora123 -- I guess that one reason that they seem obsessed with fasting levels is that they are part of the official guidelines for diagnosing diabetes (though I have to admit my GP wasn't when initially fasting was still high, but HbA1c was normal).
My personal experience is though that for me fasting levels tend to set the tone for the entire day. So, if fasting blood sugars are higher, so are levels throughout the day. That's why they matter to me personally.
Do I believe that fasting blood sugars really matter in terms of health if they are a little elevated and drop throughout the day as they do for you? No, not really. Personally, I believe that what really does harm is if we repeatedly see very high spikes throughout the day (based on the discussion by Jenny Ruhl on her bloodsugar101 website).
By the way, when you say that you HCPs want it between 4 and 5, do you mean 5.0 mmol as a maximum?
Anyway, back to main purpose of this post. Fasting levels for me were 5.1.
