Good glucose levels vary depending on whether you are fasting, after meals, or have diabetes. Here are general guidelines:
-
Fasting Blood Sugar (before eating):
- Normal: 70–99 mg/dL
- Prediabetes: 100–125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Postprandial (2 hours after eating):
- Normal: Less than 140 mg/dL
- Prediabetes: 140–199 mg/dL
- Diabetes: 200 mg/dL or higher
-
A1C Levels (average over 2–3 months):
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
These ranges may vary slightly depending on individual health conditions and guidelines from healthcare providers. Always consult your doctor for personalized targets.
