I’m not well versed on the effects of lowering bgs quickly v slowly. I vaguely remember a discussion about this at Joslin’s family camp years ago, but I remember it in the context of bgs constantly changing from high to in range and back again. That left an impression with me that is different from lowering an isolated bg back into range. Because of this context, I’ve always interpreted the danger or damaging effects to be related to a constantly swinging bg level. That’s just my interpretation though, and likely influenced by irrational emotions that high bgs elicit in me.
We’re usually pretty aggressive about higher bgs, invoking super bolus methods to get back into range sooner rather than later. They are fairly infrequent though, and using Loop technology, we have become a little less aggressive bc the risk of sustaining that high if it gets there is lower than without the help of Loop.
