Over 1988-2018, blood glycemic levels among type II diabetes-diagnosed adults decreased from 7.63% to 7.31%. The shift in medicine use and effectiveness of available medication played a significant role compared to underlying health status, demographic characters, and individual characteristics. We identify diabetic pills as a significant contributor to improving American diabetic health. However, our findings suggest that the maximum potential of diabetic control is not realized due to offsetting behavior among people diagnosed with type II diabetes. New policies could focus on shifting attitudes/preferences towards healthier choices to realize healthier lives.
