How much does your insulin dose vary, especially for women? This is out of pure curiosity, since obviously everyone is different depending on diabetes type and insulin sensitivity and whether you have any insulin production left and so on.
Since starting on the Dexcom, I’ve found that my insulin doses shift dramatically about twice a month. I sort of knew this before the Dexcom, but since getting it I’ve realized just how dramatic it is! And it really does happen overnight!
For example, yesterday and today (over the past 36 hours) I’ve experienced “The Drop” as I call it. In that time, I lowered all my basal rates by 0.3 u/hr, my I:C ratio went from 1:8 to 1:12, and my ISF went from 2.0 to 2.8 (36 to 50). And I’m still running low-ish and having to eat extra carbohydrates with no bolus on occasion, so I may end up lowering some things a bit more, though I’ve managed to avoid most lows, with the exception of almost all of yesterday morning, because I acted so quickly.
Since starting the Dexcom, sometimes I’ve anticipated hormones falsely and changed settings only to have my blood sugar go high or low because I shouldn’t have touched anything. I’ve found that having my basal rates off by 0.05 u/hr can make the differnece between me staying in range constantly and me running at 11 mmol/L (200 mg/dl) constantly. I’m not particularly insulin sensitive, but it seems like my body has some minimal threshold for basal that, if I cross, I can’t get highs down no matter how much I correct until I put my basal rates back up.
And yet, when my basal rates need changing because of hormones, they change dramatically—and fast. Over the past few months I’ve found that my insulin dose changes by 20-25 units overnight twice a month, once upward and once downward. Unfortunately, not totally predictably, so it’s not something I can put on a calenard and have a formula for.
I’ve decided to give the opposite of The Drop a name, probably something like The Rise, because I picture an evil being rising from the depths. I need to get more aggressive at attacking it when it appears, but I’m always nervous that it’ll be one of those times that I’m just imagining things and I’ll crash really low. The one great thing is that, with the Dexcom, I’m able to keep my average lower than it ever was before, even during the weeks of chaotic highs.
Anyone else? I’m guessing I’m not alone in this monthly insanity.
