I hope this question makes sense....I hope I can articulate it. Our overnight basal needs keep dropping (meaning we go low between 2-5 am if we do not adjust every week or so). Is a proper basal rate supposed to keep the glucose at a steady rate or does it "aim" for a certain "target point/range" in the absence of a correction bolus? Last night he went to bed at 172. It was a full day of activity at the amusement park so instead of giving a correction and potentially fighting lows all night we decided to get some sleep and recheck in 2 hours. He stayed 150-172 for almost 4 hours. We increased by +30% at our 2 am check and that brought him slowly down to around 110 at wake-up. Okay, then the night before, at the same basal rate he started out the night at 130 steady. Left it alone all night and he woke up at 80. What I'm trying to figure out is......if you have a set basal rate, should it hold you steady within a certain glucose range or drop you to a lower target range by a certain number of hours. I'm not finding the answers in our references easily. Thanks a bunch for any insight....I feel like so many factors can affect things and causes lows (and I'm aiming to correct some sleep deprivation so I can work part-time!) that at night unless he's over 200 I am shying away from correction boluses. Maybe that's an issue too.
