what is a good average blood sugar level

A good average blood sugar level can vary depending on whether you have diabetes, prediabetes, or no diabetes. Here are general guidelines:

• Normal (No Diabetes): An A1C level below 5.7% or an estimated average glucose (eAG) of less than 117 mg/dL.
• Prediabetes: An A1C level between 5.7% and 6.4% or an eAG of 117–137 mg/dL.
• Diabetes: An A1C level of 6.5% or higher or an eAG of 140 mg/dL or higher.

For most people with diabetes, the target A1C level is less than 7%, which corresponds to an eAG of about 154 mg/dL. However, individual targets may vary based on age, health conditions, and other factors. Always consult your healthcare provider for personalized goals.

A1C (%) eAG (mg/dL)

5.7 117
6.0 126
6.5 140
7.0 154
8.0 183

Note: Blood sugar levels can fluctuate, so regular monitoring and consultation with a healthcare professional are essential.
