Every morning I get up and have breakfast and then go for a shower, have a shave etc… and then get ready for work. Typically I will be off the pump just before I get in the shower and re-connect after I’ve had a shave, about 20 minutes. However, if I also do a set change I am off the pump for about 30 minutes. At this time in the morning I am on a Basal rate of 0.4 U.Hr.
What I am finding, especially if I do a set change is that 2 hours after I have taken my Basal and eaten I’m getting really high readings. E.g
@ 06:30 my BG was 5.8, I ate 40g of carb and took 4 units as a Bolus
@ around 07:30 I disconnected for a shower and set change
@ around 08:00 I reconnected
@ 08:30 my BG was up at 11.5.
I know that if I don’t eat in the morning and do a series of fasting tests my BG never goes up by more than 1 mmol and I know that my Insulin:carb ratio in the morning is 1 unit:10g Carb. I also know that the breakfast I had this morning while I was on MDI would never have raised my BG by more than 2 mmol.
So what is causing the highs? Could it be that if I’m off the pump for 30 minutes I’m missing out on 0.2 units of Bolus and this combined with my BG rising, because I’ve eaten, is causing me to go high.
Should I take 0.2 units as a Basal just prior to disconnecting or just after reconnecting for the 30 minutes I’m off the pump for the shower and set change?
Another thing I had thought (but I haven’t seen on fasting days) was that at 05:30 my Basal goes from 0.325 to 0.4, could this increase in insulin in my system be triggering other hormones in my body and releasing glucose into my system.
