When your pump says you're BG is going to run low but you just ate an hour ago and are still processing carbs, does it take that into consideration? I don't want to try to correct an almost low but messing up and eating too much when my BG really would be ok.
This is where our brains come into the picture - and probably why I won't go for the bionic pancreas/automatic insulin suspension combo. Only we know what we will be doing the next hour or so, what kind of carbs we consumed, and eventually we have a good idea of how long insulin/carbs last in our bodies. Taking into account the IOB as well, I decide to perhaps do a little juice (4 oz?) and seeing how I am doing in 15-20 minutes.
