Diabetes Risk Calculator

Check your type 2 diabetes risk using the Indian Diabetes Risk Score (IDRS) - the only validated screening tool specifically designed for the Indian population.

Indian Diabetes Risk Score (IDRS)
For men: <80 cm = low risk · 80–89 cm = moderate · ≥90 cm = high

India's Diabetes Crisis

100 Million+ Affected

India has over 100 million people with diabetes - the second highest in the world - and an estimated 136 million with pre-diabetes who are largely unaware.

India-Specific Thresholds

South Asians develop diabetes at younger ages and lower body weights than Western populations. IDRS uses Indian-specific waist cutoffs validated for our population.

Reversible at Early Stage

Pre-diabetes and early-stage type 2 diabetes are reversible with lifestyle changes. Knowing your risk early gives you the best chance to act before damage occurs.

Three Simple Steps

1
Answer 4 Questions

Select your age group, enter your waist measurement, choose your activity level and indicate your family history of diabetes.

2
Get Your IDRS Score

The calculator sums your risk-factor scores (0–90) and maps them to Low, Moderate or High risk using ICMR-validated thresholds.

3
Take the Right Action

Follow the recommended action for your risk level - from lifestyle maintenance for low risk to immediate blood glucose testing for high risk.

Who Should Use This Tool

Adults Over 35

ICMR recommends all Indians above 35 be screened for diabetes. This tool provides a quick first check before a blood test.

Families with Diabetes History

If one or both parents have diabetes, your risk is significantly higher. Use IDRS to quantify your risk and motivate preventive action.

Desk-Job Professionals

Sedentary office workers in India face rapidly increasing diabetes rates. Check your risk and use the result to motivate lifestyle changes.

Healthcare Camps

Doctors and NGOs conducting community health camps use IDRS to triage who needs a blood glucose test without expensive equipment.

Post-Pregnancy Check

Women who had gestational diabetes are at significantly higher lifetime risk of type 2 diabetes. IDRS helps assess ongoing risk.

Corporate Wellness

HR and wellness teams use IDRS in employee health programmes to identify high-risk individuals who need preventive counselling.

Diabetes Risk Calculator - IDRS India Assessment

India is the world's second-largest diabetic nation, with approximately 101 million people living with diabetes as of 2023 - according to the Indian Council of Medical Research (ICMR). The Indian Diabetes Risk Score (IDRS), developed by Dr. V. Mohan and colleagues at the Madras Diabetes Research Foundation in 2005, is a validated, low-cost screening tool designed specifically for the Indian population. It uses four parameters - age, abdominal obesity (waist circumference), physical activity level, and family history of diabetes - to calculate a risk score without requiring any blood tests.

Why Indians Are at Higher Risk

South Asians, including Indians, develop Type 2 diabetes at lower BMI levels compared to Western populations - a phenomenon linked to higher visceral fat accumulation, insulin resistance, and genetic predisposition. The ICMR recommends using waist circumference (above 90 cm for men and 80 cm for women) rather than BMI as a more accurate obesity marker for Indians. Urban lifestyle changes - sedentary jobs, high-carbohydrate diets, and stress - have accelerated diabetes onset to as early as the 30s in Indian city dwellers.

Understanding Your Score

An IDRS score below 30 indicates low risk, 30-50 indicates moderate risk, and above 50 indicates high risk - warranting a clinical blood glucose test. This calculator produces one of three risk categories with actionable advice. Early detection can prevent or delay the onset of Type 2 diabetes through diet modification, exercise, and medical supervision. Consult a qualified physician for a formal diagnosis.

Frequently Asked Questions

The IDRS is a validated screening tool developed by the Madras Diabetes Research Foundation specifically for Indians. It uses four risk factors - age, waist circumference, physical activity and family history - to produce a score from 0 to 90. Below 30 is low risk, 30–59 is moderate, and 60+ is high risk. It is recommended by ICMR as a first-line community screening tool.

South Asians develop type 2 diabetes at younger ages, at lower BMIs and with less overall obesity than Western populations. Higher rates of abdominal visceral fat and genetic predisposition mean standard Western risk tools underestimate risk in Indians. The IDRS uses India-specific waist thresholds validated across 26,000+ participants in pan-India studies.

For Indian men, 90 cm or above is high risk; 80–89 cm is moderate. For Indian women, 85 cm or above is high risk; 75–84 cm is moderate. These thresholds are lower than Western guidelines because South Asians accumulate dangerous visceral fat at smaller waist sizes, increasing the risk of insulin resistance at lower body weights.

A high score does not mean you have diabetes - it means your risk is elevated and you should be screened immediately with a fasting blood glucose or HbA1c test. Consult your doctor. Lifestyle changes - losing 5–7% of body weight, exercising 150 minutes weekly and reducing refined carbohydrates - can cut your progression risk by 58% even at high risk.

No. IDRS is a screening tool - it estimates relative risk, not whether you have diabetes. A diagnosis requires a blood test: fasting plasma glucose ≥ 126 mg/dL, 2-hour post-load glucose ≥ 200 mg/dL, or HbA1c ≥ 6.5%. If your score is 30 or above, consult a doctor for formal blood testing.

The IDRS has a sensitivity of 72.5% and specificity of 60.1% for detecting undiagnosed diabetes in Indian populations, outperforming Western tools like the Finnish FINDRISC and the ADA Risk Test. It was validated in the Chennai Urban Rural Epidemiology Study (CURES) and a national study spanning 26,000+ participants across 11 Indian cities.
