what is a average blood sugar level

The average blood sugar level, often measured over a period of 2-3 months, is typically assessed using the A1C test. Here’s a breakdown of what the results mean:

A1C Level (%) Blood Sugar Status

Below 5.7% Normal
5.7% - 6.4% Prediabetes
6.5% or above Diabetes

• Normal: Below 5.7% A1C, which corresponds to an estimated average glucose (eAG) of less than 117 mg/dL.
• Prediabetes: 5.7% to 6.4% A1C, indicating an eAG of 117-137 mg/dL.
• Diabetes: 6.5% or higher A1C, reflecting an eAG of 140 mg/dL or more.

For daily monitoring, normal fasting blood sugar levels are typically between 70-100 mg/dL, and post-meal levels should generally be below 140 mg/dL. However, individual targets may vary based on health conditions and medical advice.
