As an example from the opposite perspective, consider the following:
I was diagnosed three years ago with T2, then changed to a LADA diagnosis. Tested normal A1c and BG 1 year prior to diagnosis (i.e., no long-term hyperglycemia).
I’ve kept an A1c between 4.6-5.2% since three months post-diagnosis.
I was diagnosed with “moderate to severe mixed neuropathy” in both legs about six months ago.
Neither my doctor nor I could figure out how this can/should happen. Meanwhile, the consulting/diagnosing neurologist says: “Well, it just happens this way sometimes. We don’t know why.”
Then I find out two weeks ago that my Dad, my older brother, my paternal Grandfather (none diabetic) also have mixed neuropathy in both legs, and my younger brother (prediabetic) and my youngest brother (LADA) both have early symptoms and indications (loss of bloodflow and sensation, etc.) in both legs.
So, this leads me to three conclusions:
A) We often assume that certain conditions are complications of diabetes, when in some (many?) cases they can be not-at-all or loosely correlated.
B) In my family’s case, there is clearly some highly heritable condition that leads to mixed neuropathy in the legs.
C) My family’s genetics freaking suck.
