Understanding Prediabetes

 

Key Information

  • The Silent Warning: Prediabetes is like an amber warning light on a car dashboard. You cannot feel it, but it signals your body needs attention before more serious problems develop.
  • The Difference: Unlike Type 2 Diabetes, which may cause symptoms such as thirst or fatigue, prediabetes is usually symptomless. Testing is essential.
  • A Window of Opportunity: Prediabetes is not a diagnosis of failure. It gives you time to make changes and prevent progression.
  • The Solution: In many cases, prediabetes can be managed — and even reversed — through diet, exercise, and weight management.

What Happens Next?

If you identify with the risk factors listed below, the next step is a simple blood test.

We check your blood sugar levels to see whether your “amber light” is on. Detecting this early allows you to take control and reduce your risk of developing Type 2 Diabetes.

When to Contact Us

Because prediabetes does not cause symptoms, you should request a check if you fall into any of the following higher-risk categories:

  • Age & Heritage: You are over 40, or over 25 if you have a South Asian, Chinese, Black African, or Black Caribbean heritage.
  • Family History: You have a close family member (parent or sibling) with Type 2 Diabetes.
  • Physical Health: You are carrying extra weight or have high blood pressure.
