Diabetes Mellitus is no longer just a health concern it is a massive global economic force, with diabetes health spending already at USD 966 billion in 2021 and projected to reach USD 1 trillion by 2045. Behind those totals are sharp contrasts that matter, from huge underdiagnosis and widening life expectancy losses in low income settings to diabetes accounting for 10% of all US healthcare spending. Let’s put these figures side by side and see how the human burden turns into dollars, delays in care, and missed productivity worldwide.
