The Cost of Diabetes
The American Diabetes Association (Association) released new research on March 22, 2018 estimating the total costs of diagnosed diabetes have risen to $327 billion in 2017 from $245 billion in 2012, when the cost was last examined.
This figure represents a 26 percent increase over a five-year period.
The study, Economic Costs of Diabetes in the U.S. in 2017, was commissioned by the Association and addresses the increased financial burden, health resources used and lost productivity associated with diabetes in 2017. The study includes a detailed breakdown of costs along gender, racial and ethnic lines, and also includes a breakdown of costs on a state-by-state basis
