Diabetes Risk Calculator
Estimate your Type 2 diabetes risk using the Indian Diabetes Risk Score — validated for South Asian populations.
This is a screening tool only, not a diagnosis. Consult a doctor for blood sugar testing and medical advice.
About the Indian Diabetes Risk Score (IDRS)
The IDRS was developed by Dr. V. Mohan and colleagues at the Madras Diabetes Research Foundation, specifically validated for South Asian and Indian populations. It uses four easily measured factors — age, waist circumference, physical activity and family history — to estimate risk without requiring blood tests.
Diabetes prevention tips for India
White rice, maida, and sugary drinks spike blood glucose. Replace with millets, oats, whole wheat, and dals. Eat rice with a lot of vegetables and protein to slow absorption.
Even brisk walking for 30 minutes a day significantly reduces Type 2 diabetes risk. Physical activity improves insulin sensitivity and helps maintain healthy waist circumference.
Abdominal obesity (a large waist) is a key risk factor, especially for South Asians who tend to accumulate visceral fat at lower BMIs than Western populations.
Frequently asked questions
Why is the IDRS different from Western risk calculators?
South Asians develop Type 2 diabetes at lower body weights and younger ages than Western populations. The IDRS uses waist circumference thresholds validated for Indians (men ≥90 cm, women ≥80 cm) rather than higher Western cut-offs, making it more accurate for Indian people.
I have a high score. Does that mean I have diabetes?
No. A high IDRS score means you are at higher risk and should get a blood glucose test done. Only a fasting plasma glucose ≥126 mg/dL or HbA1c ≥6.5% confirms a diabetes diagnosis. Many high-risk individuals do not yet have diabetes.
Can young people get Type 2 diabetes?
Yes, India has seen rising rates of Type 2 diabetes in people under 35, often linked to sedentary lifestyles, urban diets high in refined carbs and sugar, and genetic predisposition. Young people with family history should be screened regularly.
What blood tests should I ask my doctor for?
Ask for a Fasting Plasma Glucose (FPG) test, Post-Prandial Glucose (2-hour PPG), and HbA1c. If any value is borderline, your doctor may recommend an Oral Glucose Tolerance Test (OGTT).
Can I reverse pre-diabetes?
Yes. Pre-diabetes (fasting glucose 100–125 mg/dL) can be reversed in many people through weight loss of 5–7% body weight, 150 minutes of moderate exercise per week, and a low-glycaemic diet. Studies show lifestyle changes are more effective than medication in preventing progression to Type 2 diabetes.
