I know this is kind of a basic question, and I thought that the answer was insulin works at the same rate regardless as to whether it's a correction or given to cover food, but either we are way off with her correction factor or maybe I am wrong and insulin works faster when there is no food involved. I've been wondering lately if we are WAY off with our correction factor with my daughter. I think her honeymoon is coming to a close because we are seeing higher numbers than usual. We haven't done a ton of corrections since her honeymoon started, so we never changed her correction factor since she left the hospital. However, she seems to come down really quickly with correction doses. Tonight - she was 241 at bed (4th of July BBQ, lots of grazing and guessing and all) and her correction factor is supposed to be 1 unit for 50 points. I gave her 1.5 units, which mathematically should have brought her down 75 points over some time frame (1 hour? 2 hours? 3 hours?). But, an hour later she tested and she was 69. This is not uncommon, I can't seem to correct her these days without her becoming low and having to eat. Because she ate some carbs to bring her back up to an OK place for bed, I can't tell how the situation would have played out if the insulin had just worked its way through her system. Would she have kept going down or does correction insulin finish up in an hour or so? Using this time as an example, if we used an hour as the cycle for the insulin, her correction factor would be 1 unit for 114 points, but if it's three hours, then maybe it should be 1 unit for upwards of 275 points - which would make giving a correction really hard since we switched to pens and the minimum dose is a 1/2 unit. I know I need to change her correction factor; it's just that her having to eat every time I correct her is making it hard for me to figure out what her real factor is.
