what is the average glucose level

The average glucose level can vary depending on whether a person has diabetes, prediabetes, or normal blood sugar levels. Here’s a general guide:

• Normal: For individuals without diabetes, the average glucose level is typically between 70-99 mg/dL when fasting and less than 140 mg/dL two hours after eating.
• Prediabetes: Fasting glucose levels are usually between 100-125 mg/dL, and post-meal levels may range up to 140-199 mg/dL.
• Diabetes: Fasting glucose levels are 126 mg/dL or higher, and post-meal levels are 200 mg/dL or higher.

For people with diabetes, the A1C test is often used to estimate average glucose levels over the past 2-3 months. The A1C results are reported as a percentage, and the corresponding average glucose levels are:

A1C % Estimated Average Glucose (mg/dL)

6 126
7 154
8 183
9 212
10 240

For most people with diabetes, the target A1C level is less than 7%, which corresponds to an average glucose level of about 154 mg/dL. However, individual targets may vary based on health conditions and doctor recommendations.
