Normal blood sugar levels can vary slightly depending on age, but general guidelines are as follows:

Normal Blood Sugar Levels by Age

Age Group Fasting Blood Sugar (mg/dL) Blood Sugar 2 Hours After Eating (mg/dL)

Children 70–100 Less than 140
Adults 70–100 Less than 140
Older Adults 70–130 Less than 180

Key Notes:

  • Fasting Blood Sugar: Measured after not eating for at least 8 hours.
  • Postprandial Blood Sugar: Measured 2 hours after eating.
  • Older Adults: May have slightly higher targets due to increased risk of hypoglycemia.

Always consult with a healthcare provider for personalized targets, especially if you have diabetes or other health conditions.
