Risk screening
About 1 in 3 adults have prediabetes, and roughly 80% don’t know it. There usually aren’t symptoms — that’s why a short risk questionnaire is more useful than a symptom checker. This tool runs on your device. No account, no upload.
What are the symptoms of prediabetes?
For most people, there aren’t any. The body compensates for rising blood sugar long before glucose readings cross the diabetic threshold. A few subtle insulin-resistance signs sometimes appear — velvety dark patches on the back of the neck or armpits (acanthosis nigricans), new skin tags, post-meal energy crashes, increased thirst or urination, slow-healing cuts — but most people who have prediabetes have none of these. Risk factors predict it better than symptoms, which is what this tool uses.
If any of these apply, don’t use a screener — seek care
Marked thirst, frequent urination, unexplained weight loss, vomiting, confusion, or very high home glucose readings warrant prompt medical attention rather than a risk questionnaire.
What this is
A faithful implementation of the Finnish Diabetes Risk Score (FINDRISC), the 8-item non-lab screener used by Diabetes UK, the NHS “Know Your Risk” check, and many European primary-care services. Beneath the score we surface ADA-recognised risk flags— they don’t change the FINDRISC total (that would invalidate its published risk percentages) but they matter for your conversation with a clinician.
What this is not
A diagnosis. Only a blood test (HbA1c, fasting glucose, or oral glucose tolerance test) interpreted by a clinician can tell you whether you have prediabetes. Use the result here as a prompt to ask for one if your score warrants it.
What helps
The Diabetes Prevention Program showed that losing 5–7% of body weight and 150 minutes/week of moderate activity cut 3-year T2D incidence by ~58%, and the effect persists 20+ years later. See your plan for personalised lifestyle interventions if you’ve completed the full intake, or take the intake to build one.
