A diagnosis of type 2 diabetes is becoming much more common among children.
The most likely explanation is the increase in the number of children who are overweight. Being overweight is the primary risk factor for type 2 diabetes in children. About 85% of children with type 2 diabetes are obese, and obesity in children is rising.2 As a result, diseases affecting obese and overweight people are showing up in younger people, mainly type 2 diabetes.
Too little physical activity and too much high-calorie food cause a child to become overweight, increasing his or her risk of developing type 2 diabetes early in life.
