About 79 million Americans have prediabetes and many of them do not know it. A study done at Emory University showed benefit from early detection and treatment. Diet and exercise has been shown to lower the chance of prediabetes developing into frank Diabetes type 2 by 60% over 10 years. Metformin can lower the chance by 30%. The goal should be achieving and maintaining normal levels of blood sugar. The consequences of type 2 Diabetes have impacted the health care system and caused significant individual misery. The authors of the study recommend health care providers screen their patient and consider interventions if the fasting sugar is >110 and the 2 hour post prandial sugar is >140. Prediabetes is associated with an increased incidence of blindness, kidney disease, heart attacks, strokes, and non truamatic amputations. Hopefully with early detection and treatment, there will be improvement in the incidence of these complications.
