Prediabetes often has no clear symptoms, so the best way to know if you have it is through blood tests. Here are the key tests and their results:
-
A1C Test: Measures your average blood sugar over the past 2-3 months.
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
-
Fasting Blood Sugar Test: Measures blood sugar after an overnight fast.
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary drink.
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
If your results fall in the prediabetes range, your doctor may recommend lifestyle changes like diet, exercise, and weight loss to prevent progression to type 2 diabetes.
