I'm type idiosyncratic according to my doc. Just after diagnosis I was GAD+ and extremely low Cpep, so diagnosis was auto immune type one. Insulin resistance went up to 150u to 10g carb, so type two diagnosis. Now I am GAD- and normal, non-diabetic range Cpep.Possibly a very stupid question, but does it really make any significant difference if one is LADA or T2 and insulin dependent, as the treatments seem to be very much the same.
And here's the fun bit, I usually top out at about 120u per 10g, but if I catch a vomiting bug I can go all the way down to 0u per 10g (or non-diabetic for ~24hrs or so, since my pancreas is still producing).
So type two on insulin can reduce their insulin requirements, but type LADA are always going to need a standard (for the individual) amount.
Or you can throw a spanner in the works and be ex-auto immune with insulin resistance like me.
And the original question, when I'm at the high dose end, one slice of toast will take me from a bg of 5 to a bg of over 30. Unsurprisingly, the docs really want that lower, and insulin is the everyday way. (I could spend 6-8 hrs a day every day throwing up, and that would also work. Not happening.)
