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.
The data presented at the Italian Barometer Diabetes Forum 2025 confirms an alarming trend. The risk increases with age: it reaches 15.5% among 65 to 74-year-olds and exceeds 20% among over 85-year-olds. 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 does not 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, medications, 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 tiredness.
8 early warning signs to keep in mind:
| # | Symptom | Biological mechanism |
|---|---|---|
| 1 | Excessive thirst | Overloaded 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 if you have: mental confusion, rapid breathing with acetone odor, sudden vomiting, loss of consciousness. These are signs of diabetic ketoacidosis — a potentially fatal acute 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 load 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 necessary. Any anomaly should always be discussed with your general practitioner.
Why home blood sugar monitoring changes everything
Home self-monitoring is recognized by major international guidelines as an indispensable tool for diabetes management — and valuable for prevention too. It allows you to:
- Identify the real trend of blood sugar at different times of the day
- Adapt therapy more precisely with the support of a doctor
- See in real-time the effect of food and physical activity on blood sugar
- Reduce the risk of chronic complications through constant control
- Share reliable data with the diabetologist at each visit
Glucometer G1 Pro VitaeChek: 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.
| Function | Detail |
|---|---|
| Speed | Result in 10 seconds |
| Sample | Only 0.6 µL of blood — almost painless |
| Accuracy | 98% conformity vs laboratory — ISO 15197:2015 |
| Connectivity | Bluetooth 5.0 — automatic sync with the free app |
| Memory | 360 measurements with 7, 14, 30, and 90-day averages |
| Display | Large, backlit — suitable for those with vision problems |
How to use: 5 simple steps
- Wash and dry your hands thoroughly
- Insert the test strip into the glucometer
- 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, concrete, 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 sugar by 20–30%
- Monitor body weight: overweight is the main modifiable risk factor
- Regularly measure fasting blood sugar, especially if you are over 45
Who should get tested immediately?
You should measure your fasting blood sugar 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 unexplained fatigue
- You have previously had blood sugar 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 valuable window
- Home self-monitoring reduces complications significantly
- With the G1 Pro by VitaeChek, measuring blood sugar takes only 10 seconds
