Liz, I wish I could give you any advice but I’ve been dealing with the SAME issue… it’s SUPER frustrating.
I literally took over 100u in corrections yesterday (not all at once, but starting at 9am every 3-4 hours until 1am when I gave up and went to sleep) and still never dropped below 200 (last night in fact, according to dex, I climbed after going to sleep and I was above 400 for about 6 hours - despite taking a large correction via syringe before bed, I just kept climbing, then began to come down around 8:30am). I don’t know what’s going on… I’ve changed insulin, and there’s little change - it just makes NO sense, it’s like hitting a freaking wall and NOTHING is working. I ate very little yesterday as a result and I have no good explanation for any of it.
Now, the really crazy part is that I was frustrated enough last night to just leave my basal rate alone. Despite being at 400+ for an unreal amount of time, I woke up at about 9:30 at 191… and I didn’t start dropping until about 7-8 hours after the last correction shot. Yet I dropped 200+ in the span of an hour. WTF?
My TDD is usually somewhere in the 45-50u range… my pump says it gave me 104u yesterday but that does NOT include corrections via shot. I’d guess about half the corrections I used yesterday were shots, so I probably took over 150u of insulin yesterday. A sudden 3x increase in insulin usage and my #'s are absolutely scary? Something is up, and I really don’t think the problem is ME… I look at Thanksgiving and Christmas when I freely admit I pigged out, and my TDD was 66 and 67u respectively, and my #'s were just peachy.
This started Saturday when my son went to a birthday party… I didn’t bring my meter with me because I thought I was just dropping him off (which would have been a 20 minute trip), but I should have… my BG shot up via Dexcom like I had a bad site, and I felt helpless to do anything about it without my meter to confirm how high I was. I was only away for about 2 1/2 hours but in that time I went from the 130’s after lunch (with a brand new site) to 400+. I was in the upper 300’s when I finally did get home, after giving a cautious correction based on the Dex #'s.
The only thing I can presume is that something is up with my insulin… this seemed to have started with the site change Saturday, and I’m pretty sure I opened a new bottle then.
I am about to take all of the insulin I have (which is all the same lot #) and demand that Walgreen’s replace it with a different lot #. I just filled my RX about a week ago so I’m stuck with what I have unless they agree to replace it or I can get more freebies from my Endo (I might try that too).
