Understanding Prediabetes

Key Information

• The Silent Warning: Think of prediabetes as an amber warning light on a car dashboard. You cannot feel it, but it is a sign that your body needs attention before a major problem develops.
• The Difference: Unlike Type 2 diabetes, which can cause symptoms such as thirst and fatigue, prediabetes is usually symptomless. This is why testing is so important.
• A Window of Opportunity: Finding out you have prediabetes is not a diagnosis of failure. It is a valuable opportunity to make lifestyle changes that can prevent the condition from progressing.
• 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 need to check your blood sugar levels to see whether your “amber light” is on. This helps us spot the issue early and support you in taking control.

When to Contact Us

Because you cannot usually feel prediabetes, it is worth requesting a check if any of the following apply to you:

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