Insulin is a crucial medication for both type 1 diabetics (approximately 1.4 million people) and roughly 21% of type 2 diabetics (around 6.9 million people) who need it to regulate their blood glucose levels.
Data for the National Diabetes Annual Report and the CDC indicates that approximately 8.4 million Americans rely on insulin to manage their diabetes. Among them, 2.9 million adults aged 20 years or older—equivalent to 10.9% of all US adults with diagnosed diabetes—started using insulin within a year of their diagnosis.
