3.7 Million Italians Live with Diabetes: Statistics, Symptoms, and Monitoring
The numbers everyone should know
| 3.7 Million | 6.3% | 20% | +27% |
|---|---|---|---|
| Italians with diabetes | Of the population | Over 85 affected | Growth since 2000 |
Right now, as you read this, 3.7 million Italians are living with diabetes — equivalent to 6.3% of the entire population. But the most concerning part is another: a significant portion of these cases has not yet been diagnosed. Type 2 diabetes can remain silent for years, while slowly damaging the heart, kidneys, and nerves.
Data presented at the Italian Barometer Diabetes Forum 2025 confirm an alarming trend. The risk increases with age: it reaches 15.5% among those aged 65 to 74 and exceeds 20% among those over 85. For the first time in twenty years, men have surpassed women in prevalence across all age groups.
2040 Projection: According to the International Diabetes Federation, by 2040 one in ten people in Italy could have diabetes. Globally: 783 million adults affected — 1 in 8 worldwide.
The cost is enormous: diabetes costs Italy over 20 billion euros per year and reduces life expectancy by 7–8 years in those who do not achieve good glycemic control.
What is diabetes: understanding it to manage it
Diabetes mellitus is a chronic metabolic disease caused by a defect in the production or action of insulin — the hormone that regulates glucose entry into cells. When insulin doesn't work properly, sugar accumulates in the blood and progressively damages tissues.
Type 1 vs Type 2: key differences
| Characteristic | Type 1 Diabetes | Type 2 Diabetes |
|---|---|---|
| Cause | Autoimmune | Progressive insulin resistance |
| Typical age | Young age | Predominantly over 45 |
| % of cases in Italy | ~10% | ~90% |
| Treatment | Mandatory insulin | Lifestyle, medication, insulin |
| Preventable? | No | Yes, up to 58% |
Symptoms not to underestimate
Type 2 diabetes is often called "the great impostor": symptoms appear gradually and are easily confused with everyday fatigue.
8 early warning signs to keep in mind:
| # | Symptom | Biological mechanism |
|---|---|---|
| 1 | Excessive thirst | Overworked kidneys cause constant dehydration |
| 2 | Frequent urination, even at night | Glucose eliminated in urine carries away fluids |
| 3 | Unexplained fatigue | Cells do not receive usable glucose for energy |
| 4 | Blurred vision | Hyperglycemia alters the lens due to osmotic effect |
| 5 | Slow wound healing | Compromised circulation slows tissue repair |
| 6 | Tingling in hands and feet | First sign of diabetic peripheral neuropathy |
| 7 | Persistent hunger | "Starved" cells send continuous signals even after meals |
| 8 | Frequent infections | Candidiasis, cystitis: glucose promotes bacteria and fungi |
Warning — Immediate Emergency Room visit if you have: mental confusion, shortness of breath with acetone odor, sudden vomiting, loss of consciousness. These are signs of diabetic ketoacidosis — an acute, potentially fatal complication.
Blood sugar levels: reference table
Official values from the AMD/SID 2024 Standards of Care, adopted by Italian medicine:
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting blood glucose | < 100 mg/dL | 100–125 mg/dL | ≥ 126 mg/dL |
| HbA1c (glycated hemoglobin) | < 5.7% | 5.7–6.4% | ≥ 6.5% |
| OGTT (oral glucose tolerance test 2h) | < 140 mg/dL | 140–199 mg/dL | ≥ 200 mg/dL |
Important: A single high value does not constitute a diagnosis. At least two measurements on different days are required. Any anomaly should always be discussed with your general practitioner.
Why home blood glucose monitoring changes everything
Home self-monitoring is recognized by major international guidelines as an indispensable tool for diabetes management — and also valuable for prevention. It allows you to:
- Identify the actual trend of blood glucose at different times of the day
- Adjust therapy more precisely with medical support
- See in real-time the effect of food and physical activity on blood glucose
- Reduce the risk of chronic complications through constant monitoring
- Share reliable data with the diabetologist at each visit
G1 Pro VitaeChek Glucose Meter: control in 10 seconds
The G1 Pro was designed to make blood glucose monitoring simple, precise, and integrated into daily life — even for those who have never used a medical device.
| Feature | Detail |
|---|---|
| Speed | Result in 10 seconds |
| Sample | Only 0.6 µL of blood — almost painless |
| Accuracy | 98% compliance vs laboratory — ISO 15197:2015 |
| Connectivity | Bluetooth 5.0 — automatic sync with the free app |
| Memory | 360 measurements with averages for 7, 14, 30, and 90 days |
| Display | Large, backlit — suitable for those with vision problems |
How to use it: 5 simple steps
- Wash and thoroughly dry your hands
- Insert the test strip into the glucose meter
- Prick the side of your fingertip (9 adjustable depths)
- Place the small drop of blood on the strip
- Read the result in 10 seconds — it automatically syncs to the app
Complications of uncontrolled diabetes
The consequences of unmonitored diabetes are severe, tangible, and often irreversible. In Italy, among people with diabetes:
- 1 in 5 suffers from diabetic retinopathy, which can lead to blindness
- Almost 4 in 10 have kidney failure (micro or macroalbuminuria)
- 1 in 6 has diagnosed coronary artery disease
- Every 7 minutes a person with diabetes in Italy has a heart attack
- Every 90 minutes a person undergoes an amputation related to diabetes
The good news: these complications are largely preventable with early and constant glycemic control. Home self-monitoring significantly reduces premature mortality and disabilities related to the disease.
Diet, exercise, and prevention
Type 2 diabetes is one of the chronic diseases most influenced by lifestyle. With a 5–7% weight loss and 150 minutes of moderate physical activity per week, 58% of people with prediabetes do not develop diabetes. This is not a promise: it is scientific evidence.
- Reduce refined carbohydrates and simple sugars: white bread, sugary drinks, industrial juices
- Prioritize fiber and low glycemic index foods: vegetables, legumes, whole grains, fresh fruit
- 30 minutes of walking after meals lowers postprandial blood glucose by 20–30%
- Monitor body weight: overweight is the main modifiable risk factor
- Measure fasting blood glucose regularly, especially if you are over 45
Who should get tested immediately?
You should measure your fasting blood glucose today if you fit one of these profiles:
- You are over 45 years old
- You are overweight or obese (BMI > 25)
- You have a parent or sibling with diabetes
- You have had gestational diabetes in the past
- You have high blood pressure or elevated triglycerides
- You often feel tired for no apparent reason
- You have already had blood glucose between 100 and 125 mg/dL (prediabetes)
5 things to remember
- In Italy, 3.7 million people have diabetes — many without knowing it
- Type 2 diabetes is often silent for years: the signs are there, learn them
- Prediabetes is reversible with lifestyle: you have a precious window of opportunity
- Home self-monitoring reduces complications significantly
- With the VitaeChek G1 Pro, measuring blood glucose takes only 10 seconds
