Diabetes continues to be a global health challenge in 2024, with the number of individuals affected by the condition steadily rising. This article presents the latest global statistics on diabetes, providing key insights into the ongoing trends that are shaping the future of this chronic illness.
By understanding these trends, healthcare professionals, policymakers, and the general public can better grasp the impact of diabetes and the importance of ongoing efforts to manage and prevent this condition.
What is Diabetes Mellitus?
Diabetes is a chronic health condition that affects how your body turns food into energy. Normally, the body breaks down carbohydrates into glucose, which enters the bloodstream. The pancreas then produces insulin, a hormone that allows glucose to enter cells and be used for energy. In diabetes, this process is disrupted.
This condition comes in several forms, each with distinct characteristics:
- Type 1 Diabetes Mellitus (T1DM or T1D): The body’s immune system attacks and destroys the insulin-producing cells in the pancreas, leading to a complete lack of insulin.
- Type 2 Diabetes Mellitus (T2DM or T2D): The body either doesn’t produce enough insulin or becomes resistant to it, causing elevated blood sugar levels.
- Gestational Diabetes Mellitus (GDM): Occurs during pregnancy when the body cannot produce enough insulin, leading to high blood sugar levels.
Diabetes management involves monitoring blood sugar levels, adopting a healthy diet, regular physical activity, and, in some cases, medication or insulin therapy.
An Overview of World Diabetes Statistics
Diabetes is a global health concern, impacting millions worldwide. This section provides a concise overview of key statistics, including prevalence, regional variations, and trends.
Type 1 Diabetes Statistics
1. More than 1.2 million children and teenagers are living with T1D, with over half (54%) being under the age of 15.
Here are the results:
T1D can occur at any age, but it most commonly presents in children, adolescents, and young adults, which is why it was once called “juvenile diabetes.” There are two noticeable peaks in the age of onset:
- between 4 and 7 years old
- between 10 and 14 years old
Children who inherit certain genes, such as the HLA class II genes on chromosome 6, may be more susceptible to developing T1D, especially when exposed to environmental triggers like viruses.
2. India has the largest estimated number of T1D cases (229,400 per annum) in individuals under 20 years old, followed by the US and Brazil.
A 2023 study investigated the presence of autoantibodies linked to T1D in 547 patients at the Global Reference Lab in Mumbai over three years. The results showed that 53.75% of the patients tested positive.
The most common antibody detected was glutamic acid decarboxylase-65 (GAD-65), present in 45.16% of patients. The study also found that GAD-65 positivity was more prevalent in children under 12 years of age (58.86%).
These findings highlight the critical need for early antibody testing to enable timely, targeted interventions.
Type 2 Diabetes Statistics
3. T2D is the most common type of diabetes, accounting for over 90% of all diabetes worldwide.
A systematic analysis from the Global Burden of Disease Study 2019 projected future trends in T2D incidence and mortality from 2020 to 2034, using past trends and population forecasts.
The incidence of T2D is expected to rise steadily. Specifically:
| Incidence rate | Year |
| 263.53 new cases per 100,000 people | 2020-2024 |
| 274.25 per 100,000 | 2025-2029 |
| 284.42 per 100,000 | 2030-2034 |
This indicates that the number of new cases of T2D is expected to continue increasing globally, which suggests a growing public health challenge that will need to be addressed with increased prevention and treatment efforts.
4. Some microvascular complications occur two to three times more often in youth with T2D than in those of a similar age with T1D.
A study examined the prevalence of complications related to Type 1 and Type 2 diabetes in teenagers and young adults diagnosed during childhood or adolescence across five US locations.
These differences were statistically significant, indicating a higher burden of complications among those with T2D.
5. Quitting smoking reduces the risk of developing T2D by 30-40%.
Quitting smoking not only lowers the risk of developing T2D but also significantly enhances diabetes management and reduces the likelihood of complications. Research indicates that smoking disrupts blood sugar regulation, contributing to Type 2 diabetes.
Additionally, smoking raises the risk of complications like heart disease, kidney failure, and blindness. It also slows down wound healing and increases the likelihood of lower limb amputations, placing a heavy burden on healthcare systems.
6. Impaired Glucose Tolerance (IGT) affects 541 million adults, significantly increasing their risk of T2D.
IGT is a metabolic condition where blood sugar levels are elevated but not high enough to be classified as diabetes. By 2045, the number of affected individuals is expected to rise to 730 million adults, which will account for 11.4% of the global adult population.
Diabetes Quick Facts
The first recorded mention of diabetes dates back to ancient Egypt, around 1550 BCE, where it was described as a condition causing excessive urination.
Gestational Diabetes Statistics
7. An estimated 75% to 90% of pregnancy-related high blood sugar cases are linked to GDM.
GDM increases the risk of maternal mortality and serious complications during pregnancy and childbirth, such as:
- ICU admission
- Significant blood loss
- Need for a C-section
In addition, the baby may face several potential risks and complications, including:
- Stillbirth (fetal death)
- Significant birth defects in the heart and blood vessels, brain and spine, urinary system and kidneys, and the digestive system.
- Macrosomia, where the baby may grow larger than average
- Birth injury
- Hypoglycemia or low blood sugar
- Trouble breathing (respiratory distress)
- Preeclampsia
In the US, the rate of GDM has increased by 30% among young women in the past decade. This increasing prevalence is likely linked to factors such as poor diet, low physical activity, and obesity.
8. Women with a history of GDM have an 8-10 times higher risk of developing T2D and double the risk of cardiovascular disease.
(International Journal of Gynecology & Obstetrics)
Various factors contribute to a faster progression to T2D. These include:
- Hyperglycemia diagnosed in the first trimester
- Degree of glucose intolerance and insulin use during pregnancy
- Gestational age at diagnosis of GDM
- Excessive weight gain during pregnancy
- Failure to lose pregnancy weight
- Prior GDM history
- Shorter breastfeeding duration
Given rising global rates of T2D and cardiovascular disease in women, addressing pregnancy as an opportunity for early intervention is essential to improving long-term health outcomes.
Current postpartum follow-up recommendations include a 2-hour oral glucose tolerance test (OGTT), a fasting glucose test, or an HbA1c test. Although OGTT is the gold standard, it is time-consuming and challenging for many. The HbA1c test offers an alternative, but its high cost makes it unaffordable in many low- and middle-income countries.
This highlights the need for research to develop adaptable, locally suited protocols. It’s essential to stress culturally tailored postpartum screening for effective implementation across diverse populations.
Diabetes Prevalence by Country and Region
9. The Western Pacific Region, including countries like Australia and China, accounts for over a third (38%) of the total number of adults living with diabetes.
Over the past three decades, diabetes incidence in the Western Pacific has risen sharply, with significant disparities between countries. The International Diabetes Federation (IDF) forecasts a 27% rise in the number of people with diabetes in the region, reaching 260 million by 2045.
Moreover, the region also has the second-highest rate of undiagnosed diabetes at 52.9%. With disparities between countries and many undiagnosed cases, targeted interventions, better healthcare access, and early detection strategies are critically needed.
10. The North American and Caribbean Region had the lowest percentage of undiagnosed diabetes at 24.2%.
Differences in diagnosed diabetes across countries are often influenced by:
- Genetics
- Socio-economic conditions
- Healthcare system performance
- Level of awareness about diabetes among the public and healthcare professionals
The diabetes statistic suggests that this region is relatively more effective at diagnosing diabetes compared to others. However, a significant portion of the population remains undiagnosed, highlighting the need for ongoing efforts in early detection and healthcare outreach.
11. China, India, and Pakistan had the highest numbers of adults with diabetes aged 20-79 years, a trend expected to continue through 2045.
In India, the problem is further exacerbated by environmental factors, particularly air pollution. Research in Delhi and Chennai revealed that exposure to high levels of PM2.5 particles can increase the risk of developing diabetes by 22%.
These PM2.5 particles, much thinner than a strand of hair, can enter the bloodstream, leading to respiratory and cardiovascular diseases.
This connection between air pollution and diabetes highlights the need for comprehensive public health strategies that address both environmental and lifestyle factors to combat this growing epidemic.
Diabetes Quick Facts
The southeastern United States is often referred to as the “Diabetes Belt” due to its higher prevalence of the condition, linked to factors like diet, exercise habits, and socioeconomic status. It includes 644 counties spread across 15 states.
Diabetes Prevalence by Age and Gender
12. The 20–24 age group has the lowest diabetes rate, at 2.2%.
Among adults aged 75-79, diabetes prevalence was 24.0% and is expected to rise to 24.7% by 2045. The aging global population will lead to a growing proportion of individuals over 60 living with diabetes.
According to the United Nations, the world’s population is aging rapidly. Between 1974 and 2024, the percentage of people aged 65 and older nearly doubled from 5.5% to 10.3%. By 2074, this figure is projected to double again to 20.7%, with those aged 80 and above more than tripling during the same period.
These numbers emphasize the need for targeted interventions for older adults as the global demographic shifts towards an older population.
13. There are 17.7 million more men living with diabetes compared to women.
Men are more likely to have T2D than women, but a 2019 study found that this varies by region. For example, in the UK, men have higher diabetes rates than women across different ethnic groups, such as white, South Asian, and black populations.
In contrast, in the US, the difference between men and women is minimal. Interestingly, these differences also change with age. Young women have higher rates of T2D, but men have higher rates in middle age, with the rates becoming more similar later in life.
Statistics on Diabetes and its Economic Impact
14. Diabetes-related healthcare costs are projected to hit $1.03 trillion by 2030 and $1.05 trillion by 2045.
The economic burden of diabetes, particularly its acute and chronic complications, is substantial. Diabetes-related expenses account for 11.5% of global health spending. Treating complications is a major cost driver, contributing 53% of total direct costs in both Germany and the US.
Healthcare costs increase significantly with the number of complications a patient has. For those with four or more diabetes-related complications, annual expenses are 20 times higher than for individuals with diabetes but no complications.
15. In 2022, the total annual cost of diabetes in the US was $412.9 billion, comprising $306.6 billion in direct medical expenses and $106.3 billion in indirect costs.
(American Diabetes Association)
The Economic Report identifies key cost drivers for diabetes, including:
- Increased prescription medication use
- Hospital services
- Lost work productivity
Of the $412.9 billion total cost, 26% ($106.3 billion) is due to lost productivity, unemployment from chronic disability, and premature death. Reduced productivity at work, contributes $35.8 billion annually, while absenteeism accounts for $5.4 billion.
Moreover, if individuals with diabetes were employed at the same rate as those without, there would be 2 million more people in the workforce. Diabetes now consumes one in every four US healthcare dollars.
Addressing diabetes effectively could lead to substantial economic benefits and improved quality of life for millions.
Diabetes Death Statistics
16. Diabetes was responsible for 6.7 million deaths in 2021–one death every 5 seconds.
Diabetes ranked among the top 10 causes of death globally in 2021. In lower-middle-income countries, it has become an increasingly significant threat, rising from the fourteenth to the eighth leading cause of death.
In contrast, diabetes does not rank among the top 10 causes of death in high-income countries. This shift underscores the growing impact of diabetes in less affluent regions, highlighting the need for targeted public health interventions.
17. About 32.6% of diabetes deaths happen among those of working age, under 60.
Diseases that predominantly affect working-age adults can have a significant economic impact. The Middle East and North Africa region has the highest proportion of diabetes-related deaths under 60, at 24.5%, followed by the North America and Caribbean region at 18.4%.
In contrast, the Southeast Asia region sees only 6.9% of total deaths under 60 linked to diabetes. These disparities highlight the unequal economic burden that diabetes imposes across different regions, particularly in those where the working-age population is most affected.
18. The US ranks second globally in annual diabetes-related deaths, with around 0.7 million.
A 2022 study investigated the differences in diabetes mortality rates between rural and urban areas in the US from 1999 to 2018. The researchers found that diabetes mortality rates were highest in rural counties, especially among men and younger adults aged 25-54.
While mortality rates decreased in urban and medium-sized counties over time, they remained unchanged or even increased in rural areas, particularly in the rural South. The findings highlight significant disparities in diabetes outcomes based on location, with rural areas facing the highest risk.
