Hi all, I am prediabetic and decided to get myself some libre sensors to see what's what. I meet the thin/fit profile, so 177cm/66kg, 46 years old. I have been hovering between the pre-and-not area 39-44 a1c for about 5 years. I usually do a lot of exercise (cycling ~10,000km per year) although the past 6 months have been much lower due to knackering my wrist last summer.
Anyhow, I quite often get spikes over 12 when exercising. I don't know if that has been the case all the time I have been 'pre', or just a recent development. This morning example, attached, 1 hour of medium to hard effort, no food beforehand (and ~200ml of 5% yoghurt when I got back, so nothing carby). Is this 'expected'? If so is it 'bad', or is it somehow OK because it's exercise? I rarely see over 10 from actual food.
I've been trying hard to do low carb the past couple of weeks, but over xmas I was in Mallorca and really shoving any old food down me while doing a lot of cycling (75-100km per day) and I never saw such big spikes then, presumably because my body was continually in deficit. does that mean I need to ride for 3 hours per day to stay healthy? I don't think my wife will like that, even if I would!
Problem with a CGM is that a bunch of stuff happens and it's difficult to interpret. It has been very useful for some things but I feel I'm not able to fully understand and it's seemingly random at times!
