Around 25.8 million Americans have diabetes and up to 79 million may be at risk for for it.
A paper in the European Journal of General Practice
says that a simple blood test reveals an individual's risk of developing type-2 diabetes before they develop either condition — far earlier than previously believed.
In healthy people, glucose is absorbed from the blood for use by various tissues. But the cells of people with type-2 diabetes are resistant to insulin, which is produced by the pancreas and is central to regulating carbohydrate and fat metabolism in the body. These individuals have higher-than-normal blood glucose levels. People with a "prediabetes" risk of getting diabetes have blood glucose levels somewhere between normal and diabetic.
