By 2025, more than 1 in 9 adults globally live with diabetes and that figure continues to climb, even as 46% of people with the condition still do not know they have it. The financial picture is just as stark with USD 966 billion spent on diabetes in 2021 and complications driving 70% of the costs. Follow the trail from underdiagnosis and insulin affordability to disability, mortality, and rising productivity losses to see how diabetes reshapes health systems worldwide.
