Please help! What is the definition and treatment of a prediabetic person?

Prediabetes. Hi. Prediabetes is defined as a category between normal and diabetes in the fasting glucose, the oral glucose tolerance test (OGTT), and/or the A1c (different criteria for each; most commonly used is the fasting glucose). Prediabetes has a high rate of progressing to diabetes. Treatment is healthy diet & regular exercise for life, and if possible achieve & maintain ideal body weight +/- metformin.
Prediabetes. Prediabetes implies the eventual development of diabetes, which is usually genetically predetermined. So at best, aggressive management of prediabetes can delay the onset of diabetes. That being said, blood sugar measurements can be adequately controlled at times with diet and exercise alone, without medications.
