I am on a 530G pump, This is my fourth pump, so I am pretty good with it. Here’s my problem:
I have two basal settings for 10PM to 7AM: 10PM to 7AM is .225. At 7AM it raises to .65. This has been my standard rate for a very long time.
What has been happening is around 5AM my BG skyrockets. Sensor this morning shows it went from 97 at 4:53 AM to 163 at 5:23 AM. Went to bed at 110 (meter reading) and woke up at 343. That jump occurred 11 hours after dinner. This has been happening consistently for the last 6 days. Monday night, I tried raising the 10-7 basal to .250, and moved the .65 to begin at 6AM. Woke up at 25.
I am flummoxed over this. Small changes have a large negative effect, but then it is taking over 3 units of insulin to bring down the high BGs. I had also had this sort of thing happen in the evening twice during these 6 days, but those could be food related. I changed the pump out yesterday–new insulin, tubing, etc., so I am convinced it is not mechanical.
Thoughts? Ideas? THANKS!!!
