April 30, 2012 (CHICAGO) --A potentially dangerous medical condition is on the rise in young Americans who are packing on the pounds. A major study finds teens that develop diabetes will have a tougher time keeping the disease under control. Type-2 diabetes is much more dangerous in children because it's harder to treat. The study in the 'New England Journal of Medicine' followed nearly 700 children aged 10 to 17 for four years. Researchers discovered the medication typically used in adults was not as effective at controlling blood sugar in children over time. Also, children getting the disease earlier face an increased risk for complications such as heart attack and stroke.
