For people at increased risk of type 2 diabetes, suitable lifestyle changes and weight management can reduce risk. They do not provide a guarantee.
First find out your situation
A risk questionnaire cannot confirm whether you have diabetes. Blood testing and clinical assessment may be needed. Prevention is also different from managing established diabetes, where treatment and monitoring need an agreed plan.
What you can do next
Ask your GP about assessment and local prevention support. The NHS England programme is one route for eligible people in England; arrangements vary across the UK.
