Prediabetes: Are you the one in three?

Being diagnosed with prediabetes means your body is not metabolizing glucose (blood sugar) as effectively as it should. Today, one in three Americans over age 20 has prediabetes. But most of them don't know they have it—and in this case, what you don't know can hurt you.

Many people with prediabetes go on to develop type 2 diabetes. By the time a person is diagnosed with type 2 diabetes, the cells that control glucose metabolism have already lost 50 percent of their function. This damage occurs over a period of about 10 years before type 2 diabetes is diagnosed. That's why it's important to know your risks and take action to reduce them.

The good news? Even a small amount of weight loss combined with regular exercise and a healthy diet can greatly reduce the risk of type 2 diabetes.
