Hello fellow diabetics:
I’ve had T1D for about 47 years and now have a t:Slim X2 and Dexcom G5 (that, as a Medicare guy, I hope will be upgraded soon).
I’ve got a question about correction bolus and how you do or don’t adjust that if your CGM readings are going up or down.
For example, if my current BG is 200 mg/dl, my target is 100 mg/dl and my correction factor is 50 mg/dl/unit, my guess is that most of us would agree that if my current BG was FLAT at 200 mg/dl, then an appropriate correction dose would be 2 units.
However, if my current BG is 200 mg/dl (and by that I mean CGM reading which I know may not be the same thing) and is going up by 1 mg/dl/min or even 2 mg/dl/min, do you increase your correction dose and, if so, by how much? The same question, of course applies if my current CGM reading are at 200 mg/dl but dropping by 1 mg/dl/min or 2 mg/dl/min.
In other words, do you adjust correction dose based on both current value and rate of change of your CGM readings? Do you have a firm rule for determining that or do you a more gut-level adjustment?
Thanks for your consideration.
