interesting. there are a few ways to look at this depending on how you apportion negative effects of high bg &/or hyperglycemia vs floored insulin &/or hyperinsulinemia. For example,
if T1Ds are overdoing the insulin then they might be getting damage from hyperglycemic episodes and massive doses of insulin.
if T1Ds are under-doing the insulin then they might be getting damage from hyperglycemia &/or all sort of nutrient transport into cells.
Maybe neuropathy has more to do with sustained hyperglycemia which T2D may be more prone to than T1Ds? T1D could have a lower average bg but with more variability that T1Ds…
Particular tissues have a different resistance to oxidative stress and may explain which could be linked back to the particular cause, whether it depends from the blood glucose status or insulin signaling’s status
