Approximately 1.4 million adults in the Netherlands live with prediabetes, a condition where blood sugar levels are elevated but not yet high enough to be diagnosed as type 2 diabetes. While not yet a disease in itself, prediabetes signals a heightened risk for developing both type 2 diabetes and cardiovascular diseases. Often, individuals are unaware they have prediabetes as symptoms can be subtle or absent, raising critical questions about awareness, prevention, and early intervention.
Prediabetes is considered a precursor to type 2 diabetes, a condition characterized by excessive sugar in the blood, potentially leading to symptoms like increased thirst, frequent urination, fatigue, and long-term health problems such as heart disease and kidney issues. In prediabetes, blood sugar is mildly elevated, often without noticeable symptoms, yet it serves as a crucial warning sign, according to Martijn Brouwers, an internist-endocrinologist at Maastricht UMC+ and author of the book Suiker in Overvloed. He describes prediabetes as a “red flag” for the health of many, with over a million people in the Netherlands currently affected.
The Scale of the Problem: Recent Research Findings
A recent study, De Maastricht Studie conducted by Maastricht UMC+ involving over 9,000 individuals aged 40 to 75, estimates that between 1.3 and 1.5 million people in the Netherlands have prediabetes. The research highlights that prediabetes isn’t just a stepping stone to diabetes, but also a significant risk factor for cardiovascular disease. Specifically, the study found that 1 in 7 people with prediabetes developed type 2 diabetes within ten years, and 1 in 6 experienced cardiovascular events like clogged arteries, heart attack, or stroke within the same timeframe. “These are substantial numbers, especially considering many people are unaware they fall into this risk group,” says Brouwers.
How to Determine Your Risk
Diagnosing prediabetes requires a blood sugar test, explains Brouwers. While these tests aren’t routinely performed in hospitals, they are used in research settings to accurately assess the presence of type 2 diabetes. A general practitioner can conduct a simpler test – a fasting blood sugar test – where blood sugar levels are measured after an overnight fast. If results fall within a grey area, it may indicate prediabetes. However, Brouwers advises against widespread testing, suggesting individuals first utilize the Diabetes Fonds risk calculator to assess their risk of developing type 2 diabetes. If the calculator indicates an elevated risk, consulting a doctor for a blood sugar measurement is recommended.
Understanding the Causes of Prediabetes
A primary driver of prediabetes is overweight and obesity, currently affecting 50% of all adults in the Netherlands, according to Brouwers. Excess weight forces the pancreas to work harder to regulate blood sugar levels. Over time, this strain can exhaust the pancreas, leading to insufficient insulin production and a subsequent rise in blood sugar, potentially resulting in prediabetes and eventually type 2 diabetes.
Reversing Prediabetes: A Path to Better Health
The decent news is that prediabetes can often be reversed, even without medication, according to Brouwers. A healthier lifestyle is the most effective approach, encompassing weight loss, increased physical activity, and a more mindful diet. These changes can help normalize blood sugar levels, with medication only considered if lifestyle interventions prove insufficient.
Individual responsibility is key, emphasizes the diabetes specialist. “It starts with small changes: paying attention to snacks, increasing physical activity, and taking the stairs instead of the elevator. The prevalence of overweight is also linked to societal factors – our environments often discourage movement, and calorie-rich foods are readily available.”
The Role of Prevention and Government Initiatives
Brouwers believes that preventative measures require a broader societal shift, with a role for government intervention. He welcomes several initiatives proposed by the recent Jetten cabinet, including a sugar tax on pre-packaged foods and beverages containing more than 6% sugar (scheduled for 2030), aiming to incentivize manufacturers to reduce sugar content and encourage consumers to choose healthier alternatives. Restrictions on marketing unhealthy products to children are planned. According to Brouwers, these measures are crucial, as children are increasingly consuming excessive calories, leading to earlier onset of prediabetes and diabetes.
The Responsibility of Supermarkets
Brouwers also points to a responsibility for supermarkets, though he questions whether they will act proactively. Despite a National Prevention Agreement aimed at reducing obesity, smoking, and problematic alcohol use, he observes limited changes in supermarket offerings. “Promotions often feature beer, chips, and sugary drinks, continually encouraging consumers to purchase these items,” he notes. He suggests government intervention, such as agreements to remove unhealthy products from checkout areas, could create a level playing field for all supermarkets.
Undiagnosed Diabetes: A Hidden Problem
Approximately 400,000 people in the Netherlands have undiagnosed type 2 diabetes, according to the Diabetes Fonds. This lack of awareness poses a significant health risk, as prolonged, undiagnosed diabetes can lead to irreversible damage, including nerve damage, eye problems, dementia, kidney failure, and cardiovascular disease. The recent report from the Diabetes Fonds prompted a surge in users taking the online Diabetes Risk Test, with 200,000 individuals completing it in a single day.
As Diena Halbertsma, director of the Diabetes Fonds, states, the health of many individuals is at risk. “Years of living with undiagnosed type 2 diabetes can cause damage that is irreversible. The half of all people with type 2 diabetes will experience these serious complications.”
