Diabetes Mellitus is a significant contributor to the global burden of disease. This page presents data from the Institute for Health Metrics and Evaluation (IHME) Global Burden of Disease Study, showing mortality trends, country rankings, and regional patterns. Understanding the epidemiology of diabetes mellitus helps inform public health interventions and resource allocation.
This data is sourced from the Institute for Health Metrics and Evaluation (IHME) Global Burden of Disease Study 2023, processed via Our World in Data. Values represent each cause's share of total deaths (%) unless otherwise noted. Explore related mortality data using the links below.
Diabetes mellitus — encompassing type 1, type 2, and gestational forms — directly caused an estimated 1.5 million deaths in 2019, though its true mortality toll is far higher when counting deaths from cardiovascular disease, kidney failure, and infections attributable to hyperglycaemia. Type 2 diabetes accounts for over 90% of cases and is driven by obesity, physical inactivity, and genetic susceptibility. Prevalence has quadrupled since 1980, reaching 537 million adults by 2021. The Middle East, North Africa, South Asia, and the Pacific Islands report the highest age-adjusted prevalence. Diabetes accelerates atherosclerosis, is the leading cause of end-stage renal disease, and is a major risk factor for lower-extremity amputations and blindness. The economic burden is enormous: global diabetes health expenditure exceeded $966 billion in 2021. In many low- and middle-income countries, insulin access remains inconsistent, and the majority of diabetes-related complications go untreated, contributing to excess mortality that does not appear in official diabetes death statistics.
Across 210 countries, diabetes mellitus accounts for an average of 4.3% of total deaths. Regional disparities are substantial: Latin America & Caribbean has the highest regional average at 6.7%, while Europe & Central Asia records the lowest at 2.4% — a 2.7-fold difference that underscores the geographic inequality in diabetes mellitus mortality burden.
Type 2 diabetes is substantially preventable through lifestyle modification. The Diabetes Prevention Programme trial demonstrated that moderate weight loss (5-7% of body weight) combined with 150 minutes per week of physical activity reduced diabetes incidence by 58%. Population-level strategies include sugar-sweetened beverage taxation, food labelling, urban design for walkability, and school-based nutrition programmes. For those already diagnosed, glycaemic control (HbA1c targets), blood pressure management, and statin therapy dramatically reduce complication risk. Ensuring universal access to affordable insulin, metformin, and glucose monitoring is essential.
