What this diabetes risk calculator shows you
A diabetes risk calculator adds up well-established risk factors — age, sex, family history, blood pressure history, physical activity and BMI — into a single score. A higher score means a higher likelihood of being at risk for type 2 diabetes and is a signal to get checked, not a verdict.
Risk factors for type 2 diabetes
Factor
Why it raises risk
Older age
Risk rises through midlife and beyond.
Family history
A parent or sibling with diabetes increases risk.
Higher BMI
Excess weight is a major contributor.
High blood pressure
Often occurs alongside raised diabetes risk.
Low physical activity
Activity helps the body use insulin.
How to read your score
A score of around 5 or more suggests a higher risk and is worth discussing with a doctor, who can arrange a simple blood test. A lower score today is reassuring, but risk changes over time — rechecking periodically and keeping active habits is sensible for everyone.

Diabetes Risk FAQ
How is diabetes risk calculated?
This screener adds points for established type 2 diabetes risk factors —
age, sex, family history, high blood pressure history, low physical activity
and BMI. A higher total suggests higher risk and a reason to get a blood
test.
Does a high score mean I have diabetes?
No. It only flags that your risk factors are raised. Many people with a
high score don't have diabetes, and only a blood test ordered by a doctor
can diagnose it. Think of a high score as a prompt to get checked.
What score means higher risk?
As a general guide, a score of about 5 or more points to higher risk. Below
that is lower risk today, though risk can change over time, so periodic
rechecks are worthwhile.
What are the main risk factors for type 2 diabetes?
Older age, a parent or sibling with diabetes, higher BMI, high blood
pressure, and low physical activity are key factors. Some, like weight and
activity, can be improved.
Can I lower my diabetes risk?
Often, yes. Staying active, eating a balanced diet, reaching a healthy
weight and getting regular check-ups can all help reduce type 2 diabetes
risk. A doctor or dietitian can give tailored advice.
Is the diabetes risk calculator free to use?
Yes, this diabetes risk calculator is completely free, needs no sign-up, and
gives instant results in your browser. It is a screening tool, not a
diagnosis.
