Happy new year everyone!
I've got a question regarding my bolus doses. When in was dx'd in April my CDE started me off with an I:C ratio of 1:12 and my goal BG was initially 120. After reading a lot and spending time on these boards, I tried to shoot for BG's around 90-95, so I would take a bit extra bolus than my ratio indicated (basically if i calculated for 3.5 units, for example, I would round up to 4 instead of down to 3). This worked really well andi didn't get many lows. My diet was pretty strictly low-carb (at least in comparison to what I typically ate) and my first A1C test was 5.1.
Since that A1C test, my CDE challenged me to try some meals closer to my old diet so that i could be prepared for situations when low-carb might not be available and so that in could vary my diet and not fall off the low-carb wagon in a big way. I've had a few meals with more carbs than I ever imagined eating when I was first diagnosed, and for the most part my post-meal BG has been good.
What's puzzling me, though, is that my I:C seems to have changed drastically. For example, I used to take 3U for two slices of bread and now I have to take 7-8 for the same exact portion of the same exact bread. This ratio seems to be consistent across all foods and I was wondering if that drastic of a ratio change over a few months is normal, especially considering that I haven't seen a change in my Basal dose and that my BG is stable between tests.
There are a grip of factors over the last few months that I know can affect my ratio, but I'm still wondering if this much of a change is unusual. Specifically, it's a lot colder now and I know heat/cold can affect BG, I'm not nearly as active as I was before my first A1C (works been crazy) and I've obviously been eating higher levels of carbs than before (but certainly not going overboard and I certainly still have several meals a week that are nearly zero-carb).
I've got another CDE meeting next week to follow up on my last, and id love to get some perspective on this before going in for that appointment.
Thanks in advance for any info and all the best to everyone in 2013!
