The Silent Epidemic: 400,000 Unaware of Type 2 Diabetes in the Netherlands
Alarming recent research reveals that approximately 400,000 people in the Netherlands are living with type 2 diabetes without knowing it. The findings, released on Tuesday, February 10, 2026, by the Dutch Cohort Consortium and commissioned by the Diabetes Fund, highlight a significant public health challenge. Professor Miranda Schram, a leading diabetes epidemiologist, describes the situation as a “gigantic diabetes problem.”
Understanding Type 1 vs. Type 2 Diabetes
It’s crucial to differentiate between the two main types of diabetes. Type 1 diabetes is an autoimmune condition where the body doesn’t produce enough insulin. Type 2, however, is largely linked to lifestyle factors like obesity and an unhealthy diet, leading to insulin resistance and elevated blood sugar levels. Importantly, early-stage type 2 diabetes can sometimes be reversed through lifestyle changes.
The Risks of Undiagnosed Diabetes
The danger of undiagnosed type 2 diabetes lies in its potential for serious, long-term health complications. These can include nerve damage, eye problems, dementia, kidney failure, and cardiovascular disease. The Diabetes Fund estimates that half of all individuals with type 2 diabetes will eventually experience one or more of these complications.
Why So Many Cases Go Undetected?
Diabetes is often called a “silent killer” because its initial symptoms can be vague and easily dismissed. Common early signs include increased fatigue, thirst, frequent urination, and a general feeling of being unwell – symptoms that can be attributed to many other conditions. This often delays individuals, particularly those at higher risk, from seeking medical attention.
The Role of Lifestyle and Increasing Obesity
Professor Schram points to a concerning trend: increasing rates of obesity and less healthy lifestyles in the Netherlands. “People are getting fatter, exercising less, eating less healthily, and gaining more weight,” she explains. This combination significantly increases the risk of developing type 2 diabetes.
How the Numbers Were Calculated
The estimate of 400,000 undiagnosed cases is based on a comprehensive analysis of data from over 200,000 participants in eleven long-term cohort studies across the Netherlands. This large sample size provides a high degree of reliability to the findings.
What Needs to Happen Now?
The Diabetes Fund is urging individuals to be proactive about assessing their risk. They have launched a risk assessment test that asks eight simple questions about factors like waist circumference and family history of diabetes.
Beyond individual action, Professor Schram emphasizes the need for systemic changes. “We need to make healthy food more affordable and accessible, and we need to promote more physical activity,” she states. A call for political action to create a healthier environment is also being made.
Frequently Asked Questions
- What is prediabetes?
- Prediabetes is a condition where blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes. It’s a warning sign and an opportunity to make lifestyle changes to prevent the progression to diabetes.
- Can type 2 diabetes be cured?
- While there isn’t a single “cure,” type 2 diabetes can often be managed effectively through lifestyle changes, medication, or even insulin therapy. In some cases, early intervention with significant lifestyle changes can lead to remission.
- Who is at risk for type 2 diabetes?
- Risk factors include family history, obesity, physical inactivity, unhealthy diet, older age, and certain ethnicities.
