Setting targets on libre app.

Hi. I wondered what people set their libre sensor targets to. I hadn’t really bothered with it until the more recent type 1 diagnosis. Then noticed that the upper range is set at 10……but my protocol for before eating is 7. My bloods have been running high despite my current bolus only insulin at the moment, and I am getting ready to see the consultant. However, one glance at the libre shows my control to be great, over 70% in range. However if I decrease the upper level to the 7, the percentage is nearer 22%, which to me shows a more at a glance true picture and informative for my team. What have others done? Is there a reason why libre set at 10?
 
Yes, the range target you read is for type 2.
With Type 1, it is more challenging to manage insulin dosage and timing.
Therefore, for mental well being, the upper target is higher.
And, the advice is to aim for 70% in range. There is no need to reduce your upper limit.
 
The upper level is to see how often you go higher than you’d like after a meal. If you set it to 7, and that’s your pre meal target, of course you won’t see a very high percentage, you’re not meant to stay at your pre meal target the whole time. We all rise after eating, and then (hopefully) come back down to pre meal target after 4 hours or so.
I have mine set to 10, because the '70% in range' between 3.9 and 10 is what the experts have determined is the best fit for being able to lead a normal life, whilst minimising the chances of developing complications.

Thankyou, see sense in that.

Thankyou. Interesting. I wondered if this may be the case.
 
At the time when the Libres first became available the only targets we had were our pre meal ones, and I set these into my Libre. The percentage in range was very low since it is impossible for us to keep to the pre meal targets. 70% between 3.9 - 10 is great so just keep the limits as they are.
 
I have mine set to 3.9-10.0, because that's the standard. (At present, anyway, though there's discussion of a tighter range. And if you're pregnant the target is a bit tighter.)

If you find a tighter range is helpful you can certainly use that. Changing the target range just causes the software to recalculate Time in Range.

Helli makes a great point all Type 1s need exogenous insulin which is more difficult to manage ( hence peaks and troughs) in terms of matching the carb intake.
Wheras Type 2s can be on other non insulin medication which can produce a more “ steady state” BG control ( so generally less variability.
If you are a Type 2 on Insulin then you have the same general issue in managing your BG as Type 1s ( in terms of controlling the variability).

It also makes it easier for the consultant to assess your diabetes management if it is the standard 3.9-10, because that is what the guidelines are based on. If you adjust it to something else, they may not spot that in the short time allocated to an appointment and may just assume that your TIR is based on standard settings and misunderstand your situation. You can set the alarms wherever you want, but best to keep "the range" to the standard guidelines. Managing diabetes with insulin is hard enough without making it more challenging by narrowing the target range, although I appreciate that pregnant women need to do just that.
