what is a average blood sugar

Average blood sugar levels can vary depending on whether you are fasting or have eaten recently. Here are general guidelines:

• Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L) is considered normal.
• Postprandial Blood Sugar (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L) is considered normal.
• A1C Test: This measures your average blood sugar over the past 2–3 months. A normal A1C level is below 5.7%.
