Introduction
This Diabetes Risk Calculator estimates your chance of getting Type 2 diabetes. You answer 12 short questions. The tool adds up points and gives you a score out of 41. Then it tells you if your risk is low, moderate, high, or very high.
The questions cover two kinds of risk factors. Some you cannot change, like your age, sex, family history, and background. Others you can change, like your blood pressure, smoking, diet, exercise, and waist size. The calculator shows both groups side by side, so you can see what is driving your score.
You also get a "what if" number. It shows how much lower your score could be if you fixed the lifestyle items that added points. Along with that, you get a list of clear steps to take and a full breakdown of every point.
Type 2 diabetes often starts quietly, years before any symptoms show up. Knowing your risk early gives you time to act. This tool is a screening guide, not a diagnosis. If your score is high, talk to a doctor and ask for a blood sugar or A1C test.
How to use our Diabetes Risk Calculator
Answer 12 short questions about your body, health history, and daily habits. The calculator adds up your points and shows your Type 2 diabetes risk score, your risk level, a full score breakdown, and steps you can take to lower your risk.
1. Age group: Pick the age range you are in now. Risk goes up as you get older.
2. Biological sex: Choose female, male, or prefer not to say. This sets the waist size limits used in question 11.
3. Race / ethnicity: Pick the group that fits you best. Some groups have higher rates of Type 2 diabetes.
4. Family history of Type 2 diabetes: Choose "Yes" only if a parent, brother, sister, or child has Type 2 diabetes.
5. Country / region of birth: Pick the part of the world where you were born.
12. History of gestational diabetes: Choose "Yes" if you had high blood sugar while pregnant. Leave it as "No / not applicable" if you have never been pregnant.
6. Previous high blood glucose or prediabetes: Choose "Yes" if a doctor ever told you your blood sugar was high or that you have prediabetes. This item adds the most points.
7. High blood pressure: Choose "Yes" if you were told you have high blood pressure or you take medicine for it.
8. Daily tobacco use: Choose "Yes" if you smoke cigarettes every day.
9. Daily fruit and vegetable intake: Choose "Yes" only if you eat fruit or vegetables every single day.
10. Weekly physical activity: Choose "Yes" if you get 150 minutes or more of moderate exercise each week, like brisk walking.
11. Waist circumference: Measure around your waist at your belly button after you breathe out. Type the number in the box and pick cm or inches from the drop-down.

What Is Type 2 Diabetes Risk?
Type 2 diabetes happens when your body stops using insulin well. Insulin is the hormone that moves sugar from your blood into your cells. When it stops working right, sugar builds up in your blood. Over years, high blood sugar can hurt your eyes, kidneys, nerves, heart, and feet.
Type 2 diabetes builds up slowly. Many people have it for years before they know. That is why checking your risk early matters. More than 1 in 3 adults in the U.S. have prediabetes, and most of them do not know it.
Risk Factors You Cannot Change
Some things raise your risk no matter what you do. These are your non-modifiable risk factors:
- Age. Risk climbs after 45 because cells respond to insulin less well as you get older.
- Family history. If a parent, brother, sister, or child has type 2 diabetes, your risk goes up a lot.
- Race and ethnicity. Hispanic, Black, Asian American, Native American, and Pacific Islander adults get type 2 diabetes more often.
- Sex. Men tend to build harmful belly fat at a lower weight than women.
- Gestational diabetes. High blood sugar during pregnancy raises the chance of type 2 diabetes later.
You cannot change these. But knowing them tells you how hard you need to work on the parts you can change.
Risk Factors You Can Change
These modifiable factors are the ones you can act on:
- Prediabetes. Blood sugar that is high, but not high enough to be diabetes. Without action, many people with prediabetes get type 2 diabetes within 5 years. With action, many go back to normal.
- Waist size. Fat around your belly is the kind that blocks insulin most. Risk starts rising past 35 inches (88 cm) for women and 40 inches (102 cm) for men.
- Activity. Moving your muscles pulls sugar out of your blood without needing much insulin. 150 minutes a week of brisk walking is the common goal.
- Food. Fruit and vegetables add fiber, which slows how fast sugar hits your blood.
- Blood pressure. High blood pressure and insulin problems often show up together.
- Smoking. Smokers are 30 to 40% more likely to get type 2 diabetes than non-smokers.
Why Your Score Matters
A risk score is a screening tool, not a diagnosis. It shows how many warning signs you have stacked up. A high score is a signal to get a simple blood test from a doctor or clinic, either an A1C test or a fasting glucose test. Only a blood test can tell you if you have prediabetes or diabetes.
Good News: Risk Can Drop
Type 2 diabetes is often preventable. In the Diabetes Prevention Program, a large U.S. trial, people with prediabetes who lost just 5 to 7% of their body weight and walked 30 minutes a day, 5 days a week, cut their chance of getting type 2 diabetes by about 58%. For adults over 60, the drop was even bigger. Small steps, done often, work better than big changes you cannot keep.
Warning Signs to Watch For
See a doctor soon if you notice: being thirsty all the time, peeing a lot, feeling very tired, blurry vision, cuts that heal slowly, tingling in your hands or feet, or losing weight without trying.
