Often, But High Risk
Long term human research has shown that type ii dm typically develops over 20-30 years before meeting current DX definitions.
Physicians are taught that "normal" is average to include +/-sd (the central 96% of everything), is plenty good enough. The NMR lipoprofile, which measures lipoproteins, includes an Insulin
resistance score which predicts dm >10 years in advance & can help you track status.
