Type 2 diabetes does not develop overnight. It is usually preceded by a years-long preliminary stage – prediabetes. Those who recognize it early can often stop or even reverse its progression. The most important marker for this is the HbA1c value.
What is the HbA1c value?
The HbA1c – also known as "long-term blood sugar" – indicates how high the blood sugar has been on average over the last eight to twelve weeks. Unlike fasting blood sugar, it is independent of individual meals. You can read more about this topic on our page Diabetes and Blood Tests.
What values indicate prediabetes?
- under 5.7% (39 mmol/mol): normal
- 5.7–6.4% (39–47 mmol/mol): prediabetes
- from 6.5% (48 mmol/mol): indication of diabetes
The German Diabetes Society offers further verified information on their website .
Reverse Prediabetes
The most effective measures are weight reduction in cases of overweight, increased physical activity, a fiber-rich diet, and avoiding highly sugary drinks. Even moderate changes can significantly lower HbA1c.
Test Long-term Blood Sugar
With the Long-term Blood Sugar Test (HbA1c) from Probatix , you can conveniently determine your level from home. You can find more preventive tests in the category Prevention.
