I've had Type I for over 30 years. Began with Animas pumps back in 2002 and currently using the ping system. I work hard to manage my glucose levels. Not that I don't occasionally struggle to fill the shoes of my predecessor, the islets of langerhans, but i do take it seriously and typically make ends meet.
Since Monday evening though, I’ve had several high blood sugar readings that don’t make any sense. I haven’t changed anything in my normal routine or forgotten to bolus for carbs or ingested seven pizzas, etc., yet my scores keep shooting up into the 500 range for no apparent reason. Eek.
Each time this happens, I follow the procedure recommended by my endo for treating an extraordinarily high bs by using input from my bs monitor to calculate to set up an extended bolus (90/10) which, typically, brings the glucose level down more quickly than a normal bolus. My pump is programmed to make the proper adjustments and seems to be doing just that. Dosage recommendations are well within the range of what I’d expect.
No matter how long I wait, the bolus has no impact on my bs level. It's confusing. I've been attending to this stuff for a while, yet I can’t solve the mystery of what's happening. So far I've:
- replaced the infusion set (yesterday) in a new place – no effect
- run a couple of "test primes" (today) to make sure the insulin is freely flowing through the tubing and ready to flow into the cannula – it is
- taken out the cartridge and inspected it for problems (today) – didn’t find any
- reviewed the basal rate formula (today) - same as it ever was
I suppose illness could be a factor but I don’t feel sick and I’ve never before encountered a situation where I’m sick and the insulin fails to have at least *some* impact on my glucose level. So far the only “fix” has been to use a syringe to inject insulin. Yesterday, as a last ditch response, I injected several units of Novolog from the same bottle I used to fill the pump cartridge. After a bit, my glucose levels returned to baseline.
Your feedback/Input appreciated and, if you got this far, thanks for taking the time to read!
