The Staggering Global Costs of Diabetes: 2021-2050 – A Special Report

Some startling figures released by the Centers for Disease Control came out with some extraordinary numbers concerning the cases of diabetes in the U.S. alone, back in January of 2026. According to their figures, an estimated 40.1 million Americans, or about 12% of the population, were living with diabetes in 2023, and more than one in four adults with diabetes didn’t know they had the disease. In addition to the number of actual cases, approximately 115.2 million U.S. adults had prediabetes, which significantly increases the risk of developing Type Two Diabetes, heart disease, and stroke. The financial impact is enormous. In 2021, diabetes was responsible for about $640 billion in healthcare spending, accounting for roughly one out of every four healthcare dollars spent in the United States. The CDC also reports that the number of adults diagnosed with diabetes has more than doubled over the past 20 years, showing the growing need for prevention, early detection, education, and better disease management.

Most researchers and officials agree that body weight, particularly around the abdomen, can make the body’s cells less responsive to insulin. Insulin is a hormone made by the pancreas that distributes glucose (sugar) to your cells to produce energy. In people with diabetes, the body either produces insufficient insulin, produces none at all, or fails to use it effectively, leaving glucose stranded in the bloodstream rather than reaching the cells that need it. Diet is the biggest factor in developing diabetes, due to the influencing of weight gain and the foods we consume, according to the National Institutes of Diabetes and Digestive and Kidney Diseases (NIDDK).

What about Type One Diabetes?  The difference between type one and type two is that type one is caused by problems with the body’s immune system. The immune system attacks healthy cells in the body, attacking the pancreas and killing off insulin that the organ produces. Type One Diabetes is referred to as an autoimmune disease. According to the NIDDK, approximately 1.7 million American adults aged 20 and older were living with Type One diabetes and relying on insulin in 2021, representing roughly 5.7% of all adults with diagnosed diabetes and 304,000 children and young teens under the age of 20 with the disease. Type One diabetes accounts for an estimated 5% to 10% of the total diabetes population.

These statistics are just for the U.S. alone, but the costs of diabetes are a financial burden and strain on countries around the globe as healthcare systems and families face the long-term costs of managing diabetes and its complications. Which makes this report, The global economic burden of diabetes for 190 countries 2021-50: a macroeconomic modelling study, even more alarming. 

Published in Nature Communications, this research outlines the economic costs of the disease. The study estimated that diabetes could cost the global economy more than INT$5.1 trillion (INT stands for international dollars) between 2021 and 2050. The study’s headline figure of INT$5.177 trillion is based on a standard economic assumption known as a 3% discount rate. This is a method economists use to express future costs in today’s dollars. When researchers adjusted that assumption and ran the numbers differently, the projected economic burden ranged from INT$3.6 trillion to nearly INT$9.6 trillion, suggesting the true long-term cost of diabetes could be significantly larger than the study’s headline number. Out of pocket, this would cost $591 for every person on the planet, which is more than the entire annual economy of Japan, the world’s fourth-largest economy, according to the study, with the United States, China, and India taking the biggest healthcare losses.  

The study points to several reasons for economic loss, pointing to reduced labor supply, which includes taking days off, working fewer hours, going on disability, or dying too soon. The study also points to reduced investments, with money being redirected to medications, hospitalizations, and long-term care. Researchers estimate that globally, there are approximately 500 million people with diabetes and cite increasing rates of cases since 1980, driven by poor nutrition, physical inactivity, obesity, and environmental factors such as air pollution, with diabetes being the cause of 1.66 million deaths in 2021. The highest number of deaths occurred in India, China, Mexico, and the United States.

To get a more realistic picture of diabetes’s economic impact, researchers used what is known as a health-augmented macroeconomic model, or HAM. Rather than simply tallying annual costs, a HAM combines public health data with traditional economic forecasting, like labor supply, productivity, population growth, and savings, to show how diabetes doesn’t just cost money today, it steadily chips away at workforce productivity and economic growth over time. One of the biggest findings in the study was how much of the number of disability cases accounted for much of the economic loss. Diabetes can cause blindness, kidney disease, neuropathy, chronic pain, amputations, and cardiovascular disease, putting an increased burden on the economy. 

What is downright scary are the numbers from previously published studies. This one, published in The Lancet Diabetes & Endocrinology in 2017, found that an earlier global estimate placed the economic cost of diabetes at roughly $1.31 trillion in 2015, equal to about 1.8% of global GDP. The new study projects far greater cumulative losses through 2050, as millions more people are expected to develop the disease in the coming decades, underscoring just how rapidly it is escalating and how published studies like these will continue to be followed by the medical community and health officials as they watch the number of diabetes cases rise.

So what can people do to reduce their risk? Doctors have been telling the public for years to reduce the number of sugary drinks, eat less processed foods, which are high in refined carbohydrates, and contain High-fructose corn syrup (HFCS), and replace them with healthy plant-based foods. While High-fructose corn syrup does not directly cause diabetes on its own, diets high in sugary drinks and heavily processed foods containing added sugars can contribute to weight gain and insulin resistance, two major risk factors for developing type 2 diabetes.

With the current global costs of fuel and food rising everywhere, maintaining or changing your diet to help reduce these risks comes with greater challenges as you shop at your local grocery store, looking for bargains while the cost of produce and organic foods continues to climb. Reading the labels on what you buy and making healthier choices will help reduce your family’s risk of developing diabetes. The debate over who bears the responsibility for the diabetes epidemic is one that divides policymakers, public health advocates, and the food industry. 

The finger-pointing over who is responsible for the diabetes epidemic is not a simple one. Some argue that food companies have known for years that heavily processed, sugar-filled products contribute to chronic disease, and that without government stepping in, through better labeling laws, taxes on sugary drinks, or limits on marketing junk food to children, nothing will change. Others believe that people should have the freedom to make their own food choices and that the government has no business telling anyone what to eat. However, when healthy food costs more than a bag of chips, and when many lower-income neighborhoods don’t even have a grocery store nearby, personal responsibility only goes so far. The deck is stacked, and a lot of that has to do with decades of food industry influence over what ends up on store shelves and in our schools.

Pushing the government to force companies to produce healthier food will go a long way toward reducing the number of people with diabetes. At the end of the day, behind every one of those trillion-dollar figures is a person, a parent, a worker, a child, whose life has been reshaped by a disease that, in many cases, could have been prevented.
