Hi all,

I’m 48 hours into my libre 2 free trial.

The app says my average has been 6.3mmol

My highest spike has been to 8.8 and I’ve always been around 7-7.5 about two hours after eating.

My time in range has been 100% so far.

Does this sound like I’m on track and are these stats quite promising?

Thanks in advance (not sure I’ll be paying £100) a month when the trial ends but it’s been nice for an observation!
 

Also thanks for sharing this - I have own question though. This guide points to being under 8.5 at the highest end of the scale. Why does the libre record anything under 10 as being in the target area? That’s a whole 1.5mmol higher!

Thanks

I was under the impression that you could change the "range" on the Libre?

Personally I try to stay sub 6.5 at all times.

You certainly can - when you say at all times do you mean that exact reading or as an average.

If as an average my current is showing 6.3

Thanks

I mean sub 6.5 at all times, my average is something like 5.2 mmol/l

I believe the Libre was designed for people with Type 1 diabetes. It is now used by many people without diabetes (e.g. athletes) and with other type of diabetes which is fantastic.
As mentioned above, you can adjust the range to what you want.
Those of us with Type 1 have to do the full time job of a major bodily organ by correctly dosing insulin quantities and timings all day every day for the rest of our lives. The mental strain of doing this whilst maintaining a full and balanced life can be huge. Therefore, it is common for the range for Type 1 to be slightly wider (some people extend it to 12 or above) to lessen the mental impact. We need to manage our full body and mind not just our blood sugars.
 
I’ve been referring to this chart. Presume it’s accurate?

Thanks

I am - I tend to jump quite heavily with any sort of carb. I really see the significance of cutting them right down now. Thanks

That immediate visual proof is motivating isn't it?
Just wait until you see a rise from something you didn't expect! I was horrified by 2 fresh apricots and overnight oats - supposedly "healthy" but not for me.
 
I used the original Libre for a while and was able to set my personal target ranges via my Libre reader (which came as part of a pack with my first order). I set my top of range to 7-7.5 which is also what I've always used with my Contour glucose meter.

I agree with @In Response that the Libre was originally designed for T1s, so has a somewhat higher top of range limit than might suit us as T2,

(And a mini apology @RyJames - I should probably have included some of this extra information in my original response.... )
 
I don't use the reader, but in the Android app I can set the ranges for both target and alarms independently. My alarms go off at 4.2 and 14.0, but my target range is 3.9 - 10.0. The alarms might need tweaking but that's what my DE set them to. 4.2 as the lower limit works well, for me, because if I drop below 4.2 I tend to drop fast (maybe because I'm on insulin, unlike the OP). I've never had the upper alarm go off so maybe that can be discussed next time I see her
 
Thanks - I’m near the end of my trial now and these are my results. So if that continued, would that indicate a HBA1C of 31 or thereabouts?
