If you have one or more of these symptoms, see your doctor right away!

Before people develop type 2 diabetes, they may have "prediabetes" which means their blood glucose levels are higher than normal but not high enough to be diagnosed as diabetes. Long term damage to the body, especially the heart and circulatory system, may be occurring during prediabetes. Fortunately, there are things you can do to prevent or delay the development of type 2 diabetes.
