Normal Blood Sugar Levels Chart for Healthy Individuals

Simply put, blood glucose levels refer to the total amount of glucose in one’s blood at a given time. When there’s an underlying condition, blood sugar levels tend to fluctuate, like in the case of diabetes. According to the standards set by the American Diabetes Association (ADA), the average blood sugar level (HbA1c) for a healthy, non-diabetic person should be 5.7%. The table below lists the desired, normal blood glucose levels across different times of the day for a non-diabetic, healthy individual.

Fasting (empty stomach)	< 100 mg/dL
1-hour post-meal	90-130
2 hours post-meal	90-110
>5 hours post meal	70-90

Normal Blood Sugar Levels Chart for People with Diabetes

As we know, blood sugar levels fluctuate throughout the day, so it makes sense for a diabetic person to track them regularly. According to the ADA, the normal blood marker for a diabetic person is generally around 6.5% or even more. The table below lists the blood sugar levels for diabetic people by their age across different intervals of the day. 

Age Range	Normal Blood Sugar Level (mg/dL)
	Fasting	Before Meal	1-2 hrs post meal	Bedtime
