what is the normal blood sugar level in adults

Normal blood sugar levels in adults vary depending on when the test is taken. Here are the general guidelines:

• Fasting Blood Sugar (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial (2 hours after eating): Less than 140 mg/dL (7.8 mmol/L)
• A1C Test (average over 2–3 months): Below 5.7%

These values may vary slightly depending on individual health conditions and the specific guidelines used by healthcare providers. Always consult your doctor for personalized advice.
