After inserting a new infusion set last night, I woke up during the night to test my blood sugar. I was 250 mg/dl (13.8 mmol/L) and when I gave a correction bolus, my (Minimed 722) pump gave me a no delivery alarm. I tested for ketones and have large amounts of ketones. I gave an injection and changed my infusion set, which seemed to fix the problem. My blood sugar came down to 81 mg/dl (4.5 mmol/L) by the late morning and I had only low ketones.
I just tested for ketones again and I still have a small amount of ketones 12 hours later. Is this normal? How long does it take to "flush" out the ketones?
