Earlier today I complained about the effects my grilled cheese sandwich were having on my post-lunch control. Steady at 262 for about three hours — horrible! I also predicted that, once I’d biked home and headed out the door to tutor, my blood sugar would drop dramatically without any more insulin (and that’s not even counting what would happen with my six p.m. kickboxing class).
Well, my friends, I was correct. No sooner had I gotten off my bike than my CGM trend arrow started facing directly downward; by the time I’d met my tutee, I was around 178. That held steady, sans additional insulin, till the kickboxing class, and by the time I got home for dinner, my blood sugar was at 111.
So this is what I find frustrating: I’ve tested my basal rates; they’re fine. I didn’t take any additional insulin between the time of that last post, and the time I ate dinner. And sure enough, five (5!) hours later, my blood sugar had indeed dropped to a normal level — which would suggest that if I’d taken additional correction boluses (boli?) as I was tempted to do, I’d have ended up with hypoglycemia. Do other people have this problem? That is, a severely delayed reaction to “rapid-acting” insulin that only begins working once you start moving around? I’ve spoken with multiple endocrinologists and never gotten a very satisfying answer about this — the best I’ve come up with is that there could be a problem with my insertion site for my pump (in this case, I changed it recently and it was working fine). It’s one of the reasons that I think Symlin works well for me — my body reacts much, much faster to food than it does to insulin. But there are times, like this afternoon, when Symlin doesn’t do shit.
Anyway, end of story is that I came home from the gym and made myself a dinner of cabbage salad and tuna fish. Which, now that I’ve written it down, sounds disgusting. But it was actually pretty tasty. And, conveniently, almost carb-free.
Side note — remember how I asked whether in addition to the San Francisco Ferry Building, the Empire State Building might light up blue this weekend for diabetes? According to JDRF and this site, it is — check it out.
