India is facing the world’s second-largest economic burden due to diabetes, estimated at USD 11.4 trillion, according to a new international study. The United States tops the list with costs of USD 16.5 trillion, followed by China at USD 11 trillion.
The study, conducted by researchers from institutions including the International Institute for Applied Systems Analysis and the Vienna University of Economics and Business in Austria, assessed the economic impact of diabetes across 204 countries between 2020 and 2050. The findings have been published in the journal Nature Medicine.
Globally, diabetes-related costs are estimated at nearly USD 10 trillion when excluding unpaid care provided by family members, accounting for about 0.2 per cent of the world’s annual GDP. However, when informal caregiving is included, the total economic burden surges to USD 152 trillion, or roughly 1.7 per cent of global GDP.
Researchers noted that informal care alone contributes close to 90 per cent of the total economic burden, as people with diabetes live significantly longer with the condition than they face mortality risks. This extended care often forces family caregivers to reduce work hours or exit the labour market, adding to economic losses.
In purchasing power terms, the study estimated diabetes-related costs at INT$ 1.6 trillion for India, INT$ 2.5 trillion for the United States, and INT$ 1.0 trillion for China. When losses from informal care are included, the figures rise sharply, with India’s burden reaching INT$ 11.4 trillion.
For India and China, the high costs are largely driven by the sheer size of the diabetic population, while in the United States, higher treatment expenses and diversion of physical capital are the main contributors. The study also highlighted stark disparities between high- and low-income countries, noting that treatment costs form a much larger share of the burden in wealthier nations due to better access to medical care.
The researchers stressed that diabetes poses a greater economic challenge globally than conditions such as cancer or Alzheimer’s disease. They emphasized that prevention through healthier lifestyles, including regular exercise and balanced diets, remains the most effective strategy to curb both health and economic impacts. Widespread screening, early diagnosis, and timely treatment were also identified as critical measures.
According to earlier research published in The Lancet in November 2024, more than a quarter of the world’s diabetic population currently lives in India.
