Diabetes Risk Calculator — Indian Diabetes Risk Score (IDRS)
What Is Diabetes Risk?
Diabetes risk refers to the probability of developing type 2 diabetes — a condition where the body doesn't produce enough insulin or can't use it effectively. Left unmanaged over time, high blood sugar can contribute to heart disease, kidney damage, vision problems and nerve damage. Because early stages often have no obvious symptoms, risk screening tools like this one help flag concern before symptoms appear.
How This Calculator Works (IDRS)
This calculator uses the Indian Diabetes Risk Score (IDRS), a validated screening tool developed by Dr. V. Mohan and colleagues, specifically designed and studied in Indian populations. It scores four factors — age, waist circumference, physical activity, and family history — and adds them into a total score out of 100.
IDRS Scoring Table
| Factor | Criteria | Points |
|---|---|---|
| Age | Under 35 | 0 |
| 35–49 | 20 | |
| 50 and above | 30 | |
| Waist Circumference | Men <90cm / Women <80cm | 0 |
| Men 90–99cm / Women 80–89cm | 10 | |
| Men ≥100cm / Women ≥90cm | 20 | |
| Physical Activity | Regular vigorous exercise | 0 |
| Regular moderate exercise | 10 | |
| Regular mild exercise | 20 | |
| No exercise | 30 | |
| Family History | None | 0 |
| One parent | 10 | |
| Both parents | 20 |
Risk Level Categories
| Total Score | Risk Level |
|---|---|
| Below 30 | Low Risk |
| 30 – 50 | Moderate Risk |
| 60 and above | High Risk |
Example Calculation
A 52-year-old woman, waist 92cm, no regular exercise, both parents with diabetes:
- Age (50+): 30 points
- Waist (≥90cm, female): 20 points
- Activity (none): 30 points
- Family history (both parents): 20 points
- Total = 100 → High Risk
Early Warning Signs of Diabetes
- Frequent urination
- Increased thirst
- Unexplained weight loss
- Fatigue
- Blurred vision
If you notice these signs, consult a doctor for proper testing.
Tips to Reduce Diabetes Risk
- Maintain a healthy weight and waist circumference
- Exercise regularly — at least 30 minutes daily
- Eat a balanced, fibre-rich diet
- Reduce sugar and processed food intake
- Monitor blood pressure and cholesterol regularly
- Avoid smoking and limit alcohol
Limitations to Keep in Mind
- IDRS is a screening tool, not a diagnostic test
- It doesn't include blood sugar levels directly — an actual blood test (fasting glucose or HbA1c) is needed for diagnosis
- Individual risk can be influenced by factors not captured here, like diet quality or specific medical history
