It would help if they didn't just occasionally check A1C and call it screening either. It took a decade to be diagnosed as insulin resistant even though I'm not currently even pre-diabetic. But making a lifestyle change now will at least postpone my genetic predisposition. Without having other issues I wouldn't have learned what was causing my random weight gain. I also learned of things like Inositol that work at least as well as metformin but without the side effects and is actually just a B vitamin (it is naturally occurring in small doses). But that isn't profitable for the pharmaceutical industry...
