What's actually driving the rise in type 2 diabetes among younger adults and teens?

It's generally understood as multifactorial: rising rates of childhood and adolescent obesity, decreased physical activity, dietary shifts, and possibly earlier or more frequent screening catching cases that might have gone undiagnosed longer in the past. Family history and genetic predisposition still matter. A teenager with strong family history combined with these environmental shifts faces compounded risk compared to either factor alone.
