Miksi tyypin 2 diabetes on vuosia oireeton

Type 2 diabetes does not arrive overnight. Insulin resistance builds for 5-10 years before blood sugar crosses the diabetic line — and during most of that window there are no obvious symptoms. The American Diabetes Association estimates that roughly 1 in 3 adults has prediabetes, and over 80% of them do not know it.

By the time the classic triad shows up — constant thirst, fatigue, frequent urination — the pancreas has already lost a large share of its insulin-producing capacity. The good news, and the reason this page exists: the prediabetes window is reversible. The landmark Finnish Diabetes Prevention Study (Tuomilehto 2001, NEJM) showed lifestyle change cut progression to diabetes by 58%. Catching it early is the whole game.

Neljä lukua, jotka löytävät sen ajoissa

FINDRISC — 10 vuoden riskipisteesi

FINDRISC (Finnish Diabetes Risk Score; Lindström & Tuomilehto 2003) is the most-used diabetes risk questionnaire in the world. Eight questions — age, BMI, waist, activity, diet, blood pressure history, blood sugar history, family history. No blood test needed. ~2 minutes.

The score predicts your 10-year risk of developing type 2 diabetes. A score of 12-14 means roughly 1 in 6; 15-20 means roughly 1 in 3; over 20 means roughly 1 in 2. Crucially, FINDRISC was designed as the entry point: a high score is the trigger to ask your doctor for a fasting glucose or HbA1c blood test.

Vyötärö-lantio-suhde — sisäelinrasva voittaa BMI:n

Where the fat sits matters more than how much you weigh. Visceral fat — the fat packed around your organs, signalled by a wide waist — is far more metabolically dangerous than fat under the skin. The waist-to-hip ratio captures this in one number, and large studies (INTERHEART, Yusuf 2005) found it predicts cardiometabolic risk better than BMI.

A ratio above 0.90 in men or 0.85 in women (WHO cutoffs) signals central obesity even when BMI looks normal — the “skinny outside, fat inside” pattern. If your BMI is fine but your waist-to-hip ratio is high, this test catches what BMI misses.

HOMA-IR ja paastoglukoosi — mitä veresi tekee nyt

If you have recent blood test results, two numbers reveal what is happening right now. Fasting glucose: under 5.6 mmol/L (100 mg/dL) is normal, 5.6-6.9 (100-125) is prediabetes, 7.0+ (126+) twice is diabetes (ADA criteria). HOMA-IR combines fasting glucose and fasting insulin to estimate insulin resistance (Matthews 1985) — it often turns abnormal years before glucose does, making it an early warning the standard glucose test misses.

Mitä luvut yhdessä tarkoittavat — ja mikä kääntää ne

Read together, the four numbers tell a story. High FINDRISC + high waist-to-hip + normal glucose = you are in the reversible window; lifestyle now prevents most of the risk. High FINDRISC + high HOMA-IR + borderline glucose = insulin resistance is already established; this is the moment to act hard and see a doctor.

What actually reverses it (Tuomilehto 2001; Diabetes Prevention Program 2002): losing 5-7% of body weight, 150 minutes of moderate activity a week, and cutting refined carbohydrates. These three together cut diabetes progression by more than half — outperforming metformin in the head-to-head DPP trial. The earlier you start, the less you have to do.

Milloin lääkäriin

Tämä on seulonta, ei diagnoosi. Paastoglukoosi- tai HbA1c-verikoe lääkäriltä vahvistaa diabeteksen. Jos sinulla on sumea näkö, nopea painonlasku ja äärimmäinen jano yhtä aikaa: hakeudu lääkäriin tällä viikolla.
