Informal Care Drives the Largest Share of Costs
Globally, diabetes-related costs amount to nearly USD 10 trillion when excluding informal care, which represents about 0.2% of the world’s annual GDP. However, once unpaid caregiving by family members is included, the total economic burden rises sharply to USD 152 trillion, equivalent to 1.7% of global GDP.
Researchers highlighted that informal caregiving accounts for almost 90% of the total burden. Many caregivers reduce working hours or leave the labor force entirely, leading to substantial productivity losses.
Why India and China Bear Heavy Costs
In India and China, the massive economic impact is primarily due to the sheer number of people living with diabetes. In contrast, the United States’ high burden is largely driven by elevated treatment costs and the diversion of physical capital toward healthcare.
The study also noted a stark divide between high-income and low-income nations. In wealthier countries, treatment expenses account for about 41% of diabetes-related costs, compared to just 14% in lower-income nations, reflecting unequal access to long-term medical care.
Diabetes Cost Exceeds Other Major Diseases
According to the researchers, the economic damage caused by diabetes surpasses that of other major illnesses such as cancer and Alzheimer’s disease. This underscores the urgent need for preventive health strategies worldwide.
Prevention and Early Detection Are Key
Experts emphasized that promoting healthier lifestyles—such as regular physical activity and balanced nutrition—remains the most effective way to reduce diabetes prevalence. Widespread screening programs, early diagnosis, and timely treatment can significantly limit both health and economic consequences.
Notably, more than 25% of the world’s diabetic population lives in India, according to a separate study published in The Lancet in November 2024, further highlighting the scale of the challenge facing the country.
