About the Study

Are You at Risk for Developing Type 2 Diabetes?

Recent data shows that the overall prevalence of obesity in adults in the U.S. was 35.7% and Louisiana has consistently had one of the highest rates of obesity in the country. Along with the rise in obesity has been the increasing incidence of Type 2 diabetes and cardiovascular disease. Thus, there is a need to find safe and effective alternatives to prevent and treat patients at risk for developing Type 2 diabetes and cardiovascular disease.
