what is average blood sugar

Average blood sugar, also known as estimated average glucose (eAG), reflects your blood sugar levels over the past 2-3 months. It is often measured using the A1C test, which provides a percentage. Here’s a breakdown of what the numbers mean:

A1C % eAG (mg/dL) eAG (mmol/L)

6 126 7.0
7 154 8.6
8 183 10.1
9 212 11.8
10 240 13.4

• Normal: Below 5.7% (eAG < 117 mg/dL or 6.5 mmol/L)
• Prediabetes: 5.7% to 6.4% (eAG 117–137 mg/dL or 6.5–7.6 mmol/L)
• Diabetes: 6.5% or higher (eAG ≥ 140 mg/dL or 7.8 mmol/L)

For most people with diabetes, the target A1C is below 7% (eAG < 154 mg/dL or 8.6 mmol/L). However, individual goals may vary based on health conditions and doctor recommendations.
