Only One in Three Adults with Diabetes Receives Treatment in South-East Asia, WHO Warns

A staggering health gap is unfolding in South-East Asia, where only about one in three adults living with diabetes currently receive treatment, according to the World Health Organization (WHO). As of 2025, this region harbors over 279 million adults affected by diabetes—accounting for one-third of the global diabetes burden. The WHO’s findings underscore the urgent need for enhanced access to quality diabetes care, especially in low-resource settings across the region.

Widening Diabetes Crisis in South-East Asia

Diabetes—a chronic metabolic disorder characterized by high blood sugar levels—has reached alarming proportions in the WHO South-East Asia Region (SEAR). Recent estimates reveal that more than 279 million adults in this region live with diabetes, yet only about 33 million are receiving any form of protocol-based treatment, representing just one-third of the affected population. This stark treatment gap highlights a critical public health challenge that threatens to exacerbate diabetes-related complications, disability, and mortality.​

The high prevalence partly stems from rapid urbanization, sedentary lifestyles, and dietary shifts toward processed, high-sugar foods. Moreover, diagnostic delays and under-detection contribute significantly to low treatment rates, with approximately 43% of diabetes cases remaining undiagnosed.​

WHO’s Strategic Initiatives and Regional Commitments

In response, the WHO South-East Asia Region has initiated comprehensive strategies aligned with the Global Diabetes Compact, aimed at closing this treatment gap. The SEAHEARTS initiative seeks to accelerate cardiovascular disease risk reduction by placing 100 million people with diabetes and hypertension on evidence-based, protocol-driven care by 2025.

Furthermore, the “Colombo Call for Action” endorsed in 2024 outlines catalytic steps for member states to enhance diabetes prevention, diagnosis, and equitable access to affordable treatment, including insulin and self-monitoring devices, particularly through strengthening primary healthcare systems.​

Dr. Catharina Boehme, WHO Officer-in-Charge for South-East Asia, emphasized the need for age-responsive approaches to diabetes management and highlighted the critical importance of early diagnosis, continuous care, and integrating diabetes services into existing health infrastructure.​

Statistics and Context: Diabetes Burden and Economic Impact

The International Diabetes Federation (IDF) projects that diabetes cases in South-East Asia will increase by 73% within the next 25 years, reaching an estimated 185 million by 2050—nearly doubling the current prevalence. Presently, the age-standardized prevalence stands at nearly 11% among adults aged 20–79, with a significant proportion remaining undiagnosed or untreated.​

The economic toll is substantial yet underfunded. Despite housing 18.2% of the global diabetic population, South-East Asia accounts for just 1% of the global diabetes expenditure, spending roughly $12 billion USD on diabetes care. This contrasts sharply with the rising burden, suggesting underinvestment in prevention, diagnosis, and treatment services.​

Expert Perspectives on Diabetes Management

Dr. Ramesh Kumar, Endocrinologist at the All India Institute of Medical Sciences, commented, “The diabetes epidemic in South-East Asia is compounded by systemic barriers such as limited healthcare access, affordability issues, and inadequate patient education. Effective treatment requires not only medicines but also holistic lifestyle interventions and early, continuous monitoring.”

Another expert, Dr. Anita Sharma, Public Health Specialist at the Indian Council of Medical Research, added, “Innovative models that integrate diabetes management into primary healthcare, supported by government policies and community engagement, are vital to improving treatment coverage and health outcomes.”

Public Health Implications and Practical Advice

The low treatment coverage magnifies the risk of serious complications such as cardiovascular disease, kidney failure, and blindness. From a public health perspective, closing this gap is essential to reduce both the individual burden and the strain on healthcare systems.

For individuals, early screening, adopting healthy lifestyle changes—like balanced diets low in refined sugars, regular physical activity, and adherence to prescribed treatment—are critical steps. Governments and healthcare providers must enhance education, screening programs, and ensure affordable access to insulin and monitoring devices to improve disease control.

Limitations and Counterarguments

While WHO reports provide vital data, some challenges remain, such as variability in diabetes reporting and limitations in health infrastructure which may understate actual cases. Moreover, disparities between urban and rural areas, and among different socioeconomic groups, require tailored interventions.

Critics also argue that focusing solely on treatment ignores upstream social determinants—poverty, education, and food systems—that must be addressed to prevent diabetes onset in the first place.​

Conclusion

The WHO’s data shines an urgent spotlight on the diabetes treatment gap in South-East Asia and calls for concerted efforts from policymakers, healthcare workers, and communities to bridge it. Sustainable progress requires not only medical treatment access but coordinated initiatives that combine prevention, early detection, and effective, affordable long-term care.
