Several members have posted about unusual BG and insulin behavior over the last month or so -- I'm seeing something else in the last two weeks that's kind of strange.
I have a Dexcom G4 CGM. After 6 months with it, I've got a pretty good "feel" for how my BG reacts to different foods, carb amounts, glycemic index, and insulin.
I rarely, if ever, get the single or double up-arrow indicators showing rapidly changing (up or down) BG. Almost always the angled up or down arrow when it's rising or falling.
Yet, in the salt two weeks, my BG seems to be much more volatile for some reason. I haven't changed anything -- eating the same, administering insulin the same in quantity, timing, technique -- but I'm getting rapid rise/fall almost at least once a day. Over the weekend, it was almost any time I did anything that affected my BG.
Note that my control hasn't gotten worse -- I'm not swinging up to big highs, or having increased hypos. It's just that the swing after eating from 90 or so to 140-150, and then the fall back down a few hours later is happening much more steeply, and over a shorter time period.
Anyone have any idea what's happening? I'm T2, and I'm wondering if my insulin resistance is getting better, my beta cells are just now showing some revitalization after being given a break over the last 6 months, or...
I'm going to fiddle with my ratios and other stuff over the holiday break (when I can keep a close eye on things), and see if that provides any revelation.
I gotta say, though, the much quicker fall after eating looks suspiciously like improved sensitivity from a T2 perspective...
