What Is a Normal Fasting Blood Sugar? (mg/dL and mmol/L Explained)

Understanding your fasting blood sugar levels is crucial for managing your overall health, particularly if you are concerned about diabetes or prediabetes.

What Is Fasting Blood Sugar?

Fasting blood sugar refers to the glucose level in your blood after you haven't eaten or consumed any calories for at least eight hours. It’s a key indicator used to assess how well your body regulates blood sugar.

Normal Fasting Blood Sugar Ranges

Here's a breakdown of the standard interpretations for fasting blood sugar levels, using both mg/dL (milligrams per best supplement for lowering blood sugar deciliter) and mmol/L (millimoles per liter) units:

• Normal: Less than 100 mg/dL (5.6 mmol/L)
• Prediabetes: 100 to 125 mg/dL (5.6 to 6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

It's important to note that a single high reading does not necessarily mean you have diabetes. Healthcare professionals typically require multiple elevated readings on separate days to confirm a diagnosis.

Converting mg/dL to mmol/L and Vice Versa

To convert from mg/dL to mmol/L, divide the mg/dL value by 18. To convert from mmol/L to mg/dL, multiply the mmol/L value by 18.

Understanding these conversions can be useful when reading lab reports or discussing your health with medical professionals who may use different units.
