Normal Blood Sugar Levels Chart By Age: Understanding Optimal Health

Introduction:

When it comes to maintaining our health, one key factor that often gets overlooked is blood sugar levels. These levels play a crucial role in our overall well-being, and they can vary depending on our age. In this comprehensive guide, we’ll delve into the world of normal blood sugar levels chart by age, understand the significance of these ranges, and learn how to ensure our levels stay within the optimal zone.

What Is Blood Sugar?

Blood sugar, or glucose, is a type of sugar that circulates in your bloodstream and serves as a primary source of energy for your body’s cells. It’s derived from the foods you eat, particularly carbohydrates, and is regulated by insulin, a hormone produced by the pancreas.

Why Should You Measure Your Blood Sugar?

Blood sugar testing is vital for individuals of all ages. Regular monitoring allows you to detect any abnormalities early and take the necessary steps to maintain optimal health. Once you have the blood sugar test reports, it’s essential to compare your results with a normal blood sugar levels chart to understand typical ranges based on age and other factors. Here are the top reasons why blood sugar testing is essential.

• Diabetes Management: Blood sugar testing is critical for managing diabetes and preventing complications.
• Early Detection: Regular testing allows for early detection of potential health issues, such as prediabetes or insulin resistance.
• Treatment Evaluation: It helps healthcare providers assess the effectiveness of diabetes treatment plans and make necessary adjustments.
• Overall Health: Regular testing is vital for maintaining stable blood sugar levels, as fluctuations can affect energy, mood, and cognitive function.

Integrating blood sugar testing into daily routines, alongside referring to a normal blood sugar levels chart, can help ensure the maintenance of stable and healthy glucose levels.

How Is Blood Sugar Tested?

Blood sugar can be tested using various tools and methods:

1. Glucometer: A handheld device that measures blood sugar levels from a small drop of blood obtained by pricking the fingertip.

6. Wait for Result: The glucometer will display the blood glucose reading within a few seconds.
7. Record and Interpret: Record the result in a logbook or smartphone app, and interpret it based on your healthcare provider’s guidance.

Remember to follow all instructions provided with your glucometer and consult a healthcare professional if you have any questions or concerns about using the device correctly.

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
<6 yrs.	80-180	100-180	~180	110-200
6-12 yrs.	80-180	90-180	Up to 140	100-180
13-19 yrs.	70-150	90-130	Up to 140	90-150
>20 yrs.	<100	70-130	<180	100-140

Normal Blood Sugar Levels Chart for Diabetic Pregnant Women

Pregnancy can cause blood sugar levels to fluctuate because of different hormonal changes that make it tricky for the body to process the sugar. Besides other tests, it becomes important to track your HbA1c during pregnancy. If you are diabetic and pregnant, it’s a must-do to ensure things are under control. The table below lists the normal blood sugar levels for pregnant diabetic women. 

Condition	Normal Blood Sugar Level (mg/dL)
Fasting	70-89
Before Meals	89
1-2 hrs post meal	<120
Bedtime	100-140

Normal Blood Sugar Levels Chart for Prediabetic individuals

When your blood sugar levels are at the borderline for developing diabetes, doctors would call it “prediabetic.” A prediabetic individual is required to keep a tab on the blood glucose levels to stop it from turning into diabetes. The American Diabetes Association (ADA) has set the marker for a prediabetic blood sugar level to rest between 5.7% and 6.4%. The table below offers a better understanding of diabetic HBA1c levels for diabetic individuals.

Condition	Normal Blood Sugar Level (mg/dL)
