How the Diabetes Risk Calculator works
This Diabetes Risk Calculator uses the Indian Diabetes Risk Score (IDRS) — a simple, validated method that adds up four everyday risk factors into a score out of 100. No blood test, no jargon.
Answer five questions
Your age, sex, waist size, physical activity and family history of diabetes. It takes about two minutes to assess your diabetes risk.
See your score build
Each answer adds points. The dial and breakdown show your running total and which factors matter most for you.
Get your next step
Your score places you in a risk band — low, moderate or high — with clear, personalised guidance on what to do.
What does your score mean?
The IDRS sorts your result into three bands. A higher score means a higher chance of having or developing type 2 diabetes — and a stronger reason to get a blood test.
Your risk of type 2 diabetes is currently low. This is great — but risk can change with age and lifestyle.
- Keep up healthy eating and regular activity
- Re-check your score once a year
- Maintain a healthy waist size
You have a moderate chance of type 2 diabetes or prediabetes. This is the ideal stage to act — small changes now make a big difference.
- Get a fasting blood sugar or HbA1c test
- Review your diet and activity with a doctor
- Work on waist size and daily movement
You have a high chance of type 2 diabetes. This isn't a diagnosis — but it's a clear signal to get tested and speak to a doctor soon.
- See a doctor and get a blood sugar test soon
- Don't wait for symptoms to appear
- Start lifestyle changes alongside testing
A high score doesn't mean you have diabetes, and a low score doesn't rule it out completely — only a blood test can confirm it. The IDRS is a screening guide to help you decide whether to get tested. Learn more about how diabetes is diagnosed.
Why these four factors matter
This Diabetes Risk Calculator is built on the Indian Diabetes Risk Score (IDRS), developed by the Madras Diabetes Research Foundation using data from thousands of Indians. It works because these four factors are among the strongest, simplest predictors of type 2 diabetes — no blood test needed.
Age
Up to 30 pointsRisk rises as we get older, because the body gradually becomes less sensitive to insulin. In India, type 2 diabetes often appears earlier than in Western countries — frequently from the late 30s — which is why the score starts adding points from age 35.
Waist size
Up to 20 pointsFat stored around the abdomen is far more harmful than fat elsewhere — it directly drives insulin resistance. Many Indians carry this "central" fat even at a normal weight (the "thin-fat" pattern), which is why waist size, not just weight, is measured.
Physical activity
Up to 30 pointsMovement helps muscles absorb sugar from the blood, even without insulin. A largely sedentary routine — common with desk jobs and screen time — is one of the biggest modifiable risks, which is why inactivity carries heavy points.
Family history
Up to 20 pointsDiabetes has a strong genetic component. Having one parent with diabetes raises your risk; having both raises it further. You can't change your genes — but knowing this makes early testing and healthy habits even more valuable.
Two of these four are in your control. Waist size and physical activity together account for up to half the score — so even without changing your age or genes, your daily choices can meaningfully lower your risk.

Common questions
Is this diabetes risk calculator accurate?
It uses the Indian Diabetes Risk Score (IDRS), a validated screening tool developed by the Madras Diabetes Research Foundation for the Indian population. It's a reliable way to estimate risk — but it's a screening guide, not a diagnosis. Only a blood test can confirm diabetes.
Does a high score mean I have diabetes?
No. A high score means a higher chance of having or developing type 2 diabetes, and a reason to get tested. Many people with high scores don't have diabetes, and some with lower scores do — a blood test is the only way to know for sure.
How do I measure my waist correctly?
Measure around your bare abdomen at the level of your belly button, after breathing out normally. Keep the tape snug but not tight, and don't measure over thick clothing.
Is my data saved or shared?
No. The calculator runs entirely in your browser. Your answers aren't stored, saved, or shared with anyone.
How often should I check my risk?
Once a year is reasonable for most adults, or sooner if your weight, waist or activity changes. If you're over 35 or have a family history, regular blood sugar tests are a good idea too.
Can I use this if I already have diabetes?
This tool estimates the risk of developing type 2 diabetes, so it's most useful if you haven't been diagnosed. If you already have diabetes, focus on management with your doctor instead.
