Major Diabetes Complications Leading to Mortality
Diabetes significantly increases the risk of death due to a range of complications. The most common fatal complications include infections, coronary artery disease, chronic kidney disease, and cerebrovascular disease. Infections account for the highest proportion of diabetes-related deaths, followed closely by coronary artery disease, with chronic kidney disease and cerebrovascular disease also contributing substantially to mortality rates among people with diabetes 159.
Macrovascular and Microvascular Complications and Mortality Risk
Macrovascular complications such as cardiovascular disease (CVD), coronary heart disease, and peripheral vascular disease are the leading causes of death in people with diabetes. Adults with diabetes have a 2–4 times higher risk of cardiovascular events and mortality compared to those without diabetes. Microvascular complications, including chronic kidney disease, retinopathy, and neuropathy, also play a significant role in increasing mortality risk 5678+1 MORE.
Impact of Complication Burden and Duration
The risk of death rises with the number and severity of diabetes complications. Individuals with multiple complications, such as chronic kidney disease combined with retinopathy or cardiovascular disease, face a much higher risk of mortality than those with a single complication. The duration of complications also matters: the risk of death is highest soon after the diagnosis of a major complication like CVD and remains elevated over time 236.
Trends in Diabetes Complications and Mortality
In high-income countries, rates of cardiovascular complications and all-cause mortality among people with diabetes have generally declined, likely due to better management and healthcare systems. However, in low- and middle-income countries, both complication rates and mortality are increasing, especially deaths related to renal complications. Globally, the proportion of diabetes deaths attributed to vascular complications has risen, with renal complications being the main driver of this increase 457.
Diabetes, Glycemic Control, and Age
Poor glycemic control and the presence of renal complications are linked to higher mortality in people with type 2 diabetes. Younger adults with diabetes and poor glycemic control face the greatest excess risk of death, while older adults with well-controlled diabetes and no kidney disease may have mortality rates similar to or even lower than the general population .
Prediabetes and Increased Mortality Risk
Even before diabetes is diagnosed, individuals with prediabetes are at increased risk for all-cause mortality and for developing cardiovascular disease, stroke, chronic kidney disease, and some cancers. This highlights the importance of early detection and intervention to prevent progression and reduce the risk of fatal complications .
Conclusion
Diabetes complications—especially infections, cardiovascular disease, and chronic kidney disease—are major contributors to increased mortality. The risk is higher with multiple or severe complications, poor glycemic control, and in younger individuals. While some countries have seen improvements, the global burden of diabetes-related deaths, particularly from vascular and renal complications, continues to rise. Early detection, comprehensive complication screening, and effective management are crucial to reducing mortality in people with diabetes 1234+6 MORE.
