So I'm pretty sure I'm not the only one who has experienced highs that won't budge no matter how much insulin we throw at it. It seems like it happens mostly at night. Some nights he is steady at 100-120 ish. Other nights he sits at 350 and won't come down despite several (at least 3-4) corrections. I haven't established a pattern really, although it seems to be worse of he goes to bed high, and not so much if he's in range at bed time. But not always. It isn't consistent enough that we can change his basal to compensate. It seems that by the time we know it's a stubborn high it's too late to be more aggressive (if that makes any sense). He will override the pump suggestion and increase a correction sometimes, but it's kinda scary to do that, especially at night. Is it one of those things we just have to ride out (I assume it's teenager hormone-caused), hoping it will stop eventually? How do you decide if it's safe to give aggressive corrections? He would need double, or even triple, corrections some nights. Any suggestions on how to handle this? Thanks in advance.
