Worldwide Diabetes Statistics

Diabetes is costing far more than medicines, with global estimates putting the economic and health burden from direct costs to DALYs in the same spotlight as WHO warnings that early diagnosis can prevent or delay complications. The page also contrasts massive gaps in access and outcomes with the guidance behind modern care, from ADA targets like A1C under 7% for many adults to fast changing technology markets including insulin and CGM growth projections and the year to year expansion of GLP 1 and SGLT2 adoption and research.
