I just registered on the website and this is my first post. I've got T1 and I had been using MDI before I finally decided to get a pump. My last a1c was 7.5 which is considerably high. I usually try to keep my BGs higher than 7 mmol/l at work simply trying to avoid lows. However, I often used to lose control and mo matter how much I injected, my BGs were around 12-15 mmol/l. So far with the pump my numbers are not in my acceptable range but now I use less insulin (12 units basal vs. 17 units of lantus per day). Plus, I:C ratio is 1:20 now vs. 1:15. Hopefully, with help from others I can bring my BGs a bit lower.
1) I need more insulin in the morning. I work shifts so I might wake up at 5:30am or 5:30pm. I noticed that it's not only in the morning (sunrise) but when I wake up my I:C ratio is 1:10. How long after I wake up this ratio remains the same before I can use my normal 1:20?
2) My healthcare prof also changed insulin sensitivity to 3.0. Does that mean that 20 grams of carbs (10 in the morning) raise my BG by 3 mmol/l as well? Or it's only 1 unit of insulin lowers BG by 2 mmol/l?
3) When you change infusion sets and lots of insulin left in reservoir, do you dispose insulin or top up the reservoir?
4) How long does novorapid really last? I selected 4 hours by default.
These are only a couple questions. Hopefully, I will get some response.
Thank you in advance.
