For people with Type 1 who develop insulin resistance, does the insulin resistance develop slowly, or can it develop quickly over weeks/months?
Over the past six months or so I've been needing to take WAY more insulin than I used to with no obvious cause (no major change in weight, bloodwork fine, not feeling sick, etc.). I thought maybe I'd developed "double diabetes" but it developed over a period of about a month, which seems really fast to me.
I am taking the same TDD of insulin eating 55-65g of carbs per day as I was eating 250-300g per day over the summer! The other day I slacked off and ate about 225g in one day and ended up taking double the amount of insulin I would have needed before, and still had high blood sugars (had a TDD of 87u, while in the summer it would have been about 43u for that many carbs).
My endocrinologist doesn't seem to think this is a big deal, and maybe it's not and I'm finding it disturbing for no reason. I'd like to know if others have had similar experiences and maybe it is as simple as "double diabetes" (rather than some unknown medical cause, which is what I keep worrying about!). The only other thing I can think of is that for some reason Apidra has just stopped working for me.
