Before people develop type 2 diabetes, they almost always have "prediabetes"—blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes. There are 79 million people in the United States who have prediabetes. Recent research has shown that some long-term damage to the body, especially the heart and circulatory system, may already be occurring during prediabetes.
