I am a long term type 2 who began MDI a year ago January. My HbA1c was very well controlled in the mid 5%. In January 2022 I began using a T:Slim pump with C-IQ. The carb ratio and correction factor and basal rate were set to mimic MDI.
I have a smoother curve, but HbA1c has risen about .5%. When I was using MDI I was injection Lantus 3 times per day which did away with DP and FOTF, plus it got ride of the BG bump 4 hours after lunch.
During sleep mode my BG C-IQ runs high 90s to as high as 130. With MDI my night time BG was averaging in the 80 to 90 range.
I have done some tinkering, increased basal rate by .1 u, my weight doing small correction doses and for lunch and dinner doing extended bolus. I bolus an increase of 1/3 and do an extended bolus of 60%/40%.
This is working fairly well, but I don’t find C-IQ gives the numbers I like.
One more thing my diet and exercise are basically unchanged.
Any advice from those more experienced would be helpful.
