In the Diabetes world there is two standard ranges
The one pushed for the "average Type 2" - in this case the "average" T2 is overweight, has a A1C over 7.0%, should target a range of 4.0-10.0 mmols or 72-180 points at least 70% of the time
Following those guidelines will "delay" the onset of the most destructive Diabetic Complications (Retinopathy, Kidney Disease and Heart Disease) for about 10 years
That is actually a terrible goal if you think about it, but since 70% of Type 2's are "uncontrolled" even with meds that is better than the alternative
If you actually want to manage to try and prevent complications then you need to follow a much "tighter" range
Diabetes UK was the first to provide guidance on that about a decade back establishing a preferred range of 4.0-8.0 mmols or 72-144 which was altered slightly to 3.9-7.8 mmols or (Phone number can only be seen by the question and answer creators)% of the time which gave the patient the best odds of avoiding the serious complications and living to life expectancy
(before CGM's came into wide use it was tougher to establish a "range" when you are only "sticking" a couple/few times a day - CGM's changed the way (we) looked at time in range which is far more beneficial then doing an FBS and 2hr post meal reading and trying to make all our decisions from those two numbers)
As you increase your "percentage in tight range" upwards, it continues to lower your risk of developing complications such that, at about 85% TITR (tight time in range - 3.9-7.8/70-140) reduces your risk of Retinopathy, Kidney Disease, Heart Disease/Stroke and Vascular Dementia to rates for "non-diabetics"
Type 2 used to mostly be a disease/disorder/condition (pick your term - if you are "diabetic" does it matter really how you define it??) of Seniors with onset typically in your 60's
When that was true then the "looser" range was fine - when your in your 60's you may not worry as much about a condition that will take 20 years to really hurt you
But as the age of diagnosis continues to drop - where the average age now is in the 40's, Type 2's may have to manage for 4 or 5 "decades" if they want to grow old with good function - so keeping a TITR for as long as possible with any combination of lifestyle and meds is the only way any of them will live well into the retirement years with any kind of function
Yes, that sucks - but Diabetes Sucks and we either have to live with it or die from it's complications - we don't get a 3rd choice
It will also do for longer lengths of time I think up to 3mo
Thank you @A DiabetesTeam Member for the visual pic. That explains it so well.
I set my parameters .shown here in the green belt. I try to stay within that range. It will go a bit higher after meals. But come down in range
The cgm has a page for average glucose and time in target
I cannot post two pics in a reply so will send in a second reply.
