In the United States (U.S.), the costs for health care and lost productivity due to diagnosed diabetes has increased from $174 billion in 2007 to $245 billion in 2012, making it one of the fastest growing public health burdens. Nearly 26 million adults have diabetes, and another 79 million have prediabetes, a condition that increases the risk for developing type 2 diabetes. Clearly to reduce the costs and improve health, preventing diabetes must be a priority.
