Diabetes mellitus is one of the most important and fast-incriminating public health problems of the twenty-first century. Being one of the main non-communicable diseases, it has both clinical morbidity and a significant social, economic and health system burden in the global arena. In this article, the burden of diabetes mellitus is analyzed through an integrated approach that combines epidemiological trends, social determinants of health and the challenges associated with health system capacity. The incidence of diabetes has risen significantly over the past few decades worldwide, primarily due to demographic changes, urbanization, changing lifestyles and population aging, with the rate of rise being higher in low- and middle-income nations. This pattern of epidemiology highlights the importance of diabetes as a significant cause of untimely deaths, disability, as well as long-term effects, which increases the total disease burden. In addition to biological risk factors, socioeconomic status, education and living conditions, as well as access to resources, are important socioeconomic factors that determine diabetes risk, disease progression and outcomes. Disproportionate exposure to these determinants is a factor in the continued existence of health inequities, which affect not only the distribution of diabetes but also the ability of people and communities to control the disease successfully. Meanwhile, health systems in most regions are increasingly pressurized to adequately address the increase in demand of chronic disease prevention and care. Restrictions in the capacity of the health system, such as workforce gaps, disjointed service provision, lack of funding and insufficiency in managing new challenges, limit the ability to effectively control diabetes and increase the current inequities. This article integrates evidence in these areas to emphasize the idea that diabetes mellitus is a multidimensional burden that needs an integrated epidemiological surveillance that demands action on social determinants and strong and resilient health systems. This form of integration is necessary to reduce the present and future effects of diabetes on the global population.
