The normal range for blood glucose levels varies depending on whether you are fasting or have recently eaten. Here are the general guidelines:
- Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
- Postprandial (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
These values are for adults without diabetes. If you have diabetes, your target ranges may differ, and you should follow your healthcare provider's recommendations.
Condition Blood Glucose Range (mg/dL)
Normal 70–99 (fasting)
Prediabetes 100–125 (fasting)
Diabetes 126 or higher (fasting)
Always consult your doctor for personalized advice.
