Indonesia Faces Alarming Diabetes Crisis, Ranked Fifth Globally with Millions Undiagnosed and Uncontrolled

Indonesia is grappling with a severe public health crisis as new data reveals it has ascended to the fifth position worldwide for the highest number of diabetes sufferers, a grim statistic that underscores a much deeper and pervasive issue: millions of its citizens live with the chronic condition entirely unaware. The International Diabetes Federation (IDF) 2025 report paints a stark picture, identifying approximately 20.4 million Indonesians aged 20-79 years currently living with diabetes, placing the archipelago nation behind only China, India, the United States, and Pakistan in global prevalence. This alarming surge is not merely a number; it represents a burgeoning silent epidemic with profound implications for individual well-being, the national healthcare system, and the country’s economic future.

The Escalating Burden: A Global and National Perspective

The national figures align with a disturbing global trend, where the total number of people living with diabetes is projected to reach an astounding 589 million, accounting for roughly 11.1 percent of the world’s population. This upward trajectory has been consistent over the past two decades, with a significant portion of the increase observed in low- and middle-income countries like Indonesia, where rapid urbanization, changing dietary habits, and sedentary lifestyles have created a fertile ground for the disease to flourish. In Indonesia, the challenge is compounded by a significant proportion of undiagnosed cases, which healthcare experts warn is a ticking time bomb for severe complications and premature mortality.

Dr. Siti Nadia Tarmizi, Director for Prevention and Control of Non-Communicable Diseases (P2PTM) at the Ministry of Health, highlighted the gravity of the situation during a strategic collaboration discussion with the Indonesian Association of Endocrinologists (PERKENI) in Jakarta on Friday, April 17, 2026. "The problem is, many cases remain undiagnosed. Yet, diabetes mellitus (DM) is also a leading cause of disability. We must not think that living with DM is something to be taken lightly," Dr. Tarmizi emphasized. Her statement underscores the critical gap in public awareness and early detection, which allows the disease to progress silently, causing irreparable damage before symptoms become apparent. The insidious nature of diabetes, often presenting with mild or no discernible symptoms in its early stages, contributes significantly to this diagnostic lag.

The Silent Progression: Understanding the Pathophysiology and Complications

Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels, either because the body does not produce enough insulin (Type 1 diabetes), or because it cannot effectively use the insulin it produces (Type 2 diabetes). Type 2 diabetes accounts for the vast majority of cases in Indonesia and globally, heavily influenced by lifestyle factors. Dr. Tarmizi further elaborated on the destructive mechanism of uncontrolled diabetes: "High sugar levels in the bloodstream cause damage to blood vessels, leading to what we know as microvascular problems." This damage affects both small (microvascular) and large (macrovascular) blood vessels throughout the body.

Microvascular complications include retinopathy (damage to the eyes, leading to blindness), nephropathy (damage to the kidneys, progressing to kidney failure), and neuropathy (nerve damage, often affecting the feet and leading to amputations). Macrovascular complications, on the other hand, involve the larger arteries, increasing the risk of cardiovascular diseases such as heart attacks, strokes, and peripheral artery disease. The cumulative effect of these complications is what makes diabetes such a formidable health threat, drastically reducing quality of life and significantly shortening life expectancy. The lack of early diagnosis means that many Indonesians only discover they have diabetes when these severe complications have already set in, making management more challenging and outcomes less favorable.

A Crisis of Awareness and Control: The Diagnosis and Treatment Gap

The alarming statistics extend beyond mere prevalence. Data from 2024 reveals a significant chasm between the estimated number of people with diabetes and those who are actually diagnosed and effectively managed. Only about 35.4 percent of the total diabetes cases in 2024 were diagnosed by healthcare professionals. This means nearly two-thirds of those living with diabetes in Indonesia are unaware of their condition, unknowingly exposing themselves to progressive organ damage. For those fortunate enough to be diagnosed, the journey to effective management is still fraught with challenges. Only approximately 68.1 percent of diagnosed individuals receive treatment, and a mere 20.2 percent successfully achieve proper control of their disease.

This profound gap highlights a multi-faceted problem encompassing access to healthcare, affordability of treatment, adherence to medical advice, and sustained lifestyle modifications. The low rates of diagnosis and control underscore the urgent need for enhanced public health campaigns, improved screening initiatives, and more robust support systems for patients. Without adequate awareness and access to continuous care, the burden of diabetes-related complications will continue to escalate, overwhelming an already strained healthcare infrastructure.

Lifestyle: The Primary Driver of the Epidemic

Dr. Tarmizi unequivocally pointed to lifestyle as the predominant factor fueling the diabetes epidemic, particularly Type 2 diabetes, which is classified as a non-communicable disease (NCD). "Non-communicable diseases rarely affect people at a young age, but it is incorrect behavior that shifts this trend," she stated. This shift refers to the increasing incidence of Type 2 diabetes in younger populations, a direct consequence of modern lifestyles. Key risk factors identified include diets rich in sugar, salt, and fat; insufficient physical activity; and tobacco use.

A particularly concerning trend highlighted by Dr. Tarmizi is the skyrocketing consumption of sugary beverages, especially among young people. The proliferation of packaged sweet drinks, ready-to-drink coffees, bubble teas (boba), and various flavored teas has become a cultural phenomenon, leading to dangerously high sugar intake in a single sitting. These beverages, often perceived as harmless treats or daily staples, contribute significantly to caloric excess, weight gain, and insulin resistance, paving the way for diabetes. The rapid urbanization across Indonesia has also led to a more sedentary lifestyle, with less physical activity, increased reliance on motorized transport, and professions that involve prolonged sitting. Coupled with the widespread availability of processed and fast foods, these factors create a perfect storm for the development of metabolic disorders.

Economic Fallout and Healthcare System Strain

Beyond the individual suffering, the diabetes epidemic imposes a staggering economic burden on Indonesia. The disease is a significant contributor to mortality rates, often alongside other major NCDs such as stroke, heart disease, and cirrhosis. Furthermore, diabetes is intricately linked to the rising incidence of chronic kidney disease (CKD), with many individuals only discovering their underlying diabetes when they present with severe kidney issues. "People with diabetes mellitus, if their diabetes is not properly managed, tend to suffer from kidney disease," Dr. Tarmizi explained.

The financial implications are immense. Data reveals that the cost of managing diabetes-related complications, particularly kidney failure, has surged by an astounding 478 percent over the past seven years. This astronomical increase translates into billions of rupiah diverted from other essential healthcare services and significant out-of-pocket expenses for patients and their families. The burden on BPJS Kesehatan, Indonesia’s national health insurance system, is particularly heavy, as it covers the costs of long-term treatments like dialysis for kidney failure, a common and expensive complication of uncontrolled diabetes. The productivity losses due to premature death, disability, and prolonged illness further exacerbate the economic strain, impacting the national workforce and overall economic development.

Strategic Responses and Collaborative Efforts

Recognizing the escalating crisis, the Indonesian Ministry of Health, in collaboration with professional organizations like PERKENI, has been implementing various strategies to combat diabetes. These initiatives encompass a multi-pronged approach, including health promotion, disease prevention, early detection, and improved management. Programs such as "Gerakan Masyarakat Hidup Sehat" (GERMAS – Community Movement for Healthy Living) aim to foster healthier lifestyles through campaigns promoting physical activity, balanced nutrition, and regular health check-ups. The "Program Indonesia Sehat dengan Pendekatan Keluarga" (PIS-PK – Healthy Indonesia Program with Family Approach) integrates health services directly into communities, allowing for more targeted screening and education at the household level.

PERKENI, as the leading association for endocrinologists, plays a crucial role in developing clinical guidelines, training healthcare professionals, and advocating for policy changes. Their collaboration with the Ministry of Health is vital for standardizing diabetes care across the archipelago. Efforts are also being made to improve the capacity of primary healthcare facilities to screen for diabetes, diagnose cases early, and provide initial management, thereby reducing the burden on secondary and tertiary hospitals. However, the sheer scale of the problem necessitates a more aggressive and widespread approach, potentially involving stricter regulations on food labeling, taxation of sugary beverages (a "sugar tax" has been debated for years), and innovative public-private partnerships to expand access to affordable healthy food options and safe spaces for physical activity.

Timeline of Key Developments and Policy Responses (Inferred)

• Early 2000s: Initial rise in NCD prevalence noted, coinciding with rapid economic growth and urbanization.
• Mid-2010s: Ministry of Health intensifies focus on NCDs, launching national campaigns like GERMAS to promote healthy lifestyles.
• 2014: Launch of BPJS Kesehatan, significantly expanding access to healthcare, but also revealing the massive existing burden of chronic diseases like diabetes and its complications.
• Late 2010s: Increasing data points to a rapid escalation of diabetes cases, prompting more urgent calls for action. Discussions around policy interventions like a sugar tax gain traction.
• 2020-2023: Despite the COVID-19 pandemic, the underlying NCD crisis continues to worsen, with diabetes identified as a major comorbidity.
• 2025: International Diabetes Federation (IDF) report highlights Indonesia’s alarming rise to 5th globally, triggering renewed urgency in policy and programmatic responses.
• 2026 (April): Strategic discussions between the Ministry of Health and PERKENI underscore the ongoing efforts and the critical need for broader public awareness and collaborative action.

Challenges and the Path Forward

Despite the concerted efforts, significant challenges remain. Indonesia’s vast geography, with its myriad islands and diverse populations, makes uniform implementation of health programs difficult. Reaching remote communities with screening and education requires innovative approaches and substantial resources. Overcoming deeply ingrained cultural habits related to diet and physical activity also presents a formidable hurdle. Furthermore, ensuring the affordability and accessibility of essential diabetes medications and monitoring tools, particularly in rural areas, is crucial for effective disease management.

The future outlook demands a paradigm shift in how diabetes is perceived and addressed. It must transition from being seen as an individual health issue to a national public health priority requiring a whole-of-government and whole-of-society approach. Dr. Tarmizi’s emphasis on behavioral change as the cornerstone of prevention remains paramount. Reducing sugar consumption, increasing physical activity, and regular health check-ups are simple yet powerful steps that can collectively yield significant positive impact. The critical insight from the latest data is not just the sheer number of sufferers, but the millions who are living with diabetes completely unaware, unknowingly allowing the disease to wreak havoc on their bodies. Addressing this "unawareness gap" through aggressive public health campaigns, accessible screening programs, and empowering individuals with knowledge and tools for self-management will be key to reversing Indonesia’s alarming trajectory in the global diabetes landscape. The time for urgent, comprehensive action is now, to safeguard the health and future prosperity of the Indonesian nation.
