Blood sugar levels, also known as blood glucose levels, indicate the amount of glucose present in your blood. These levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Here are the general ranges for blood sugar levels:
- Normal fasting blood sugar: 70–99 mg/dL (3.9–5.5 mmol/L)
- Prediabetes (impaired fasting glucose): 100–125 mg/dL (5.6–6.9 mmol/L)
- Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests
After eating (postprandial), blood sugar levels typically rise and should return to normal within a few hours. For non-diabetic individuals, postprandial levels are usually below 140 mg/dL (7.8 mmol/L).
If you have diabetes, your target blood sugar levels may vary based on your treatment plan. Consult your healthcare provider for personalized goals.
