Early diabetes screening:
why is it essential?
In brief
Why is early diabetes screening so urgent?
Diabetes screening is an essential step in detecting this silent disease before it causes serious complications. With type 2 diabetes rising at an alarming rate worldwide, public health infrastructure is under growing strain.
Faced with this threat, early screening stands out not only as a logical solution but also as a pressing necessity to prevent the escalation of cases and to proactively manage potential complications.
Global context
According to the International Diabetes Federation (IDF), the number of people living with diabetes worldwide could reach 592 million by 2030. This increase represents a 55% rise compared to current figures. Prevention and early screening efforts are therefore more necessary than ever to mitigate the global impact of diabetes.
By recognizing and responding quickly to the early warning signs of diabetes in at-risk individuals, it becomes possible to implement interventions that can significantly alter the course of the disease and improve long-term outcomes.
Type 1 or type 2 diabetes: how to tell them apart and screen for them?
Type 1 diabetes typically presents with sudden symptoms (intense thirst, fatigue, weight loss), which usually lead to a quick diagnosis through a simple blood glucose test. Type 2 diabetes, on the other hand, calls for genuine screening — meaning an active search in someone without symptoms — particularly after age 45 or in the presence of being overweight, a sedentary lifestyle, or a family history.
Type 1 vs type 2 diabetes
Type 1 diabetes is often recognized by symptoms that appear suddenly and acutely, such as excessive thirst, frequent urination, and rapid weight loss. Type 2 diabetes, by contrast, develops more insidiously and can go undiagnosed for years, since it frequently progresses without obvious symptoms at first.
This lack of warning signs makes early screening crucial — to avoid or delay serious complications and to start appropriate treatment as soon as possible.
Risks and complications
Undiagnosed or poorly managed diabetes carries serious consequences. It can lead to a range of severe complications. Among these, cardiovascular diseases such as heart attacks and strokes are the most well-known. Nerve damage, or neuropathy, can lead to a loss of sensation, particularly in the feet, increasing the risk of unnoticed injuries and infection. In addition, kidney problems can progress to kidney failure requiring dialysis.
Each of these complications can significantly reduce quality of life, and therefore requires constant vigilance and rigorous medical follow-up to prevent them effectively.
Diabetes screening: why detect the disease as early as possible?
Early diabetes screening first and foremost helps manage the disease effectively. It also makes it possible to implement lifestyle changes that can delay or prevent the development of type 2 diabetes in people with prediabetes.
Why is early diabetes screening essential?
Early diabetes screening is essential for taking action before serious complications develop. Rapid identification makes it possible to adopt interventions that improve quality of life and reduce long-term healthcare costs. Acting on the first signs of the disease allows treatments and lifestyle changes to begin early. These can slow down or even reverse the progression of diabetes, especially in the case of type 2 diabetes.
Impact of early screening
Research confirms that preventive measures, such as dietary changes and regular physical activity, are extremely beneficial. These interventions can significantly reduce the risk of severe complications, such as cardiovascular problems or diabetic neuropathy. Early screening thus gives individuals the opportunity to take charge of their health with effective strategies tailored to their specific situation.

How does diabetes screening work?
Diabetes screening generally involves a series of simple but crucial blood tests. They can detect abnormalities in blood sugar levels. These tests are essential for identifying people at high risk of developing type 2 diabetes, or for diagnosing the disease in those who already show symptoms.
Standard tests and procedures
The main diabetes screening tests include:
- Fasting blood glucose: measured after an eight-hour fasting period, this test is the first tool used to assess diabetes risk.
- HbA1c testing: this test gives a picture of the average blood sugar level over the past two to three months.
- Le dosage de HbA1c : ce test donne une image du niveau moyen de sucre dans le sang sur les deux à trois derniers mois.
A diabetes diagnosis is confirmed when fasting blood glucose is equal to or greater than 1.26 g/L (7 mmol/L) on two occasions, or when HbA1c is equal to or greater than 6.5%. Between 1.10 and 1.26 g/L fasting, this is referred to as prediabetes — a stage that is still reversible with lifestyle adjustments.

Already diagnosed with diabetes: what additional screenings and follow-up are needed?
Already diagnosed with diabetes? Lianeli recommends a series of additional screenings to effectively manage the disease and prevent its complications. These screenings include:
- Cholesterol screening: lipid monitoring to help prevent cardiovascular disease.
- Dental follow-up: people with diabetes are more prone to dental issues such as periodontitis.
- Heart disease screening: cardiac health monitoring, essential for people with diabetes.
- Diabetic foot screening: prevention of serious complications that can lead to amputation.
- Nephropathy screening or follow-up: assessment of kidney function to detect any early deterioration.
- Blood pressure screening: monitoring blood pressure to reduce the risk of cardiovascular complications.
- Diabetic retinopathy screening: an eye exam to detect early signs of retinal damage.
Diabetes screening: take action for your health today
Diabetes prevention and early screening aren't just matters of individual health. They're also public health issues. With diabetes rates rising worldwide, it's essential to implement proactive strategies to counter this trend. Lianeli is committed to playing a leading role in this effort — by providing the tools needed for effective screening and proactive health management.
We invite everyone to recognize the importance of early screening and to use solutions like Lianeli to take charge of their health. Together, we can make a meaningful difference in the fight against diabetes and work toward a healthier future for all.
