However, when I see my diabetic nurse, they will tell me that i have too many hypos. I personally would prefer having a fairly regular minor hypo to having a high a1c. My last a1c was 5%.
I remember reading a story of a computer programmer who added this silly feature (flying ducks) to the chess game he was making because he knew his project manager would
always find something to complain about and he didn't want to have to remove or change any of the features he liked. Sure enough his manager told him to "get rid of the ducks".
Some people are never happy and I'm beginning to think the same applies to some doctors/nurses.
My A1c was not as low as that when one endo was uncomfortable with it being so low.
The time below 3.9 is less than 1% which I am happy about (the LibreView AGP report says the target is "less than 4%"), but was still told I had too many hypos. (Mind you I would probably agree).
Also this was based on the libre "Low Glucose Events" which are lows which last at least 15 minutes. I have probably as many lows that aren't counted as LGE's. (Unlike Antje77 and others, my libre responds quite quickly). I don't know whether other people agree, but I basically ignore them as, since the libre has to be deliberately excluding them, I am assuming the view is that they are not really dangerous.
I had a nurse (not a diabetic nurse) who was unhappy that I did not eat anything before going to bed despite my average blood sugar being about 7 at that time. (I don't know if it is a thing, but I have want I call 'Foot off the floor" syndrome where my BS can sometimes jump up a few minutes after I get into bed!) I didn't think it was a good idea to mention to the nurse the novorapid correction dosages I sometimes took at night.
I'm not sure I would like your percentage time below 3.9% (even knowing that it isn't accurate), but I am rather envious of your A1c and your Time in Range.
