what should an average blood sugar be

The average blood sugar level, also known as estimated average glucose (eAG), can vary depending on whether you have diabetes, prediabetes, or normal blood sugar levels. Here’s a general guide:

• Normal (non-diabetic): Below 100 mg/dL (fasting) and below 140 mg/dL (2 hours after eating).
• Prediabetes: 100–125 mg/dL (fasting) or 140–199 mg/dL (2 hours after eating).
• Diabetes: 126 mg/dL or higher (fasting) or 200 mg/dL or higher (2 hours after eating).

For people with diabetes, the A1C test is often used to measure average blood sugar over the past 2–3 months. The target A1C for most adults with diabetes is below 7%, which corresponds to an eAG of 154 mg/dL. However, individual targets may vary based on your health condition and doctor’s recommendations.
