Why do I need to know if I have prediabetes?

If you have prediabetes, you can and should do something about it. Studies have shown that people with prediabetes can prevent or delay the development of type 2 diabetes by up to 58 percent through changes to their lifestyle that include modest weight loss and regular exercise. The expert panel recommends that people with prediabetes reduce their weight by 5-10 percent and participate in some type of modest physical activity for 30 minutes daily. For some people with prediabetes, intervening early can actually turn back the clock and return elevated blood glucose levels to the normal range.
