How fast does blood sugar go up when basal is off? I am trying to make sense of the numbers. If someone gets 1.35 units an hour then wouldn't they rise by about the amount that 1.35 units usually covers? I am curious because I have seen a lot of people post that they end up over 300 with a disconnection, but I have also read about people who don't even use insulin for a couple of days at the end of a month because they run out and can't afford it. If you take 1 unit of basal an hour, and 1 unit corrects say 50 points then wouldn't you expect to rise 50 points an hour without basal if you were fasting, or does it just not work that way?
