For the past three days I've spent probably 90% of the time with my blood sugar in the 13-18 range (235-325). I've upped my pump settings (basal up 0.15 u/hr, I:C ratio from 1:12 to 1:9, ISF from 2.4 to 1.8), PLUS put a +20% temporary basal rate on top of that, and I'm STILL running high! And spilling moderate to large ketones, but only intermittently (they go away when my blood sugar goes down ... it just doesn't stay down for more than one test).
I've changed infusion sets and changed insulin in case that's it ... But I think it's just my body. Last winter something similar happened, where I ran high and had ketones for days at a time, just like now, and it kept getting worse until my pump settings were more than double what they'd been in the summer. Then in the spring it disappeared, just like that. Now, it seems to be coming back.
Can weather have that dramatic of an impact?! I mean, I live in Vancouver, which is extremely temperate. I'd hate to see what living in Toronto might do to me ... Last winter I was SURE I was sick or something and we searched high or low for some type of cause and found nothing. I seriously think it's just the weather.
