The Ultimate Blood Sugar Levels Chart by Age (And What It Means for You)

Understanding your blood sugar levels is crucial for maintaining overall health and preventing potential complications like diabetes. Whether you're checking your levels at home or reviewing lab results with your doctor, this comprehensive guide will provide you with a clear understanding of what's considered normal, what to do if your levels are high or low, and how age impacts these ranges.

Why Monitor Blood Sugar Levels?

Blood glucose monitoring is essential for several reasons:

Diabetes Diagnosis: It helps detect prediabetes and diabetes early on.
Diabetes Management: For individuals with diabetes, regular monitoring helps manage their condition effectively.
Preventing Complications: Maintaining stable blood sugar levels can prevent or delay serious complications like nerve damage (neuropathy), kidney disease (nephropathy), and cardiovascular issues.
Personalized Treatment: Understanding your blood sugar trends allows for tailored dietary and lifestyle adjustments.

Understanding Blood Sugar Readings: mg/dL vs. mmol/L

Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) in the United States and some other countries. In other regions, such as Canada and Europe, the unit of measurement is millimoles per liter (mmol/L).

Here's the conversion formula:

mg/dL = mmol/L x 18
mmol/L = mg/dL / 18

This article will primarily use mg/dL, but we'll provide conversions where relevant.

Blood Sugar Levels Chart by Age: A Comprehensive Guide

The following chart outlines the general target ranges for blood sugar levels at different times of the day, based on age. Keep in mind that individual targets may vary based on specific health conditions and treatment plans. Always consult with your healthcare provider to determine the ideal target range for you.

Age Group	Fasting Blood Sugar (mg/dL)	Fasting Blood Sugar (mmol/L)	2 Hours After Eating (mg/dL)	2 Hours After Eating (mmol/L)
Children (6-12 years)	80-120 mg/dL	4.4-6.7 mmol/L	Less than 140 mg/dL	Less than 7.8 mmol/L
Teenagers (13-19 years)	70-130 mg/dL	3.9-7.2 mmol/L	Less than 140 mg/dL	Less than 7.8 mmol/L
Adults (20+ years) (Non-Diabetic)	Less than 100 mg/dL	Less than 5.6 mmol/L	Less than 140 mg/dL	Less than 7.8 mmol/L
Adults (20+ years) (Diabetic)	80-130 mg/dL	4.4-7.2 mmol/L	Less than 180 mg/dL	Less than 10.0 mmol/L
Elderly (65+ years)	80-140 mg/dL	4.4-7.8 mmol/L	Less than 160 mg/dL	Less than 8.9 mmol/L

Important Notes:

Fasting Blood Sugar: Measured after at least 8 hours of fasting (no food or drink except water).
2 Hours After Eating: Measured approximately 2 hours after the start of a meal.
These are general guidelines; individual goals may vary.
For pregnant women, blood sugar targets may be different and should be discussed with their doctor.

What Do Different Blood Sugar Levels Mean?

Normal Blood Sugar Levels: Indicate that your body is effectively processing glucose.
High Blood Sugar Levels (Hyperglycemia): May indicate diabetes, insulin resistance, or other health issues. Symptoms can include increased thirst, frequent urination, blurred vision, and fatigue.
Low Blood Sugar Levels (Hypoglycemia): Can occur in people with diabetes taking insulin or other medications that lower blood sugar. Symptoms can include shakiness, sweating, dizziness, confusion, and rapid heartbeat. It can also occur in non-diabetics under certain circumstances.

Factors Affecting Blood Sugar Levels

Many factors can influence your blood sugar readings, including:

Diet: The types and amounts of carbohydrates you consume have a significant impact.
Physical Activity: Exercise can lower blood sugar levels.
Medications: Certain medications, like corticosteroids, can raise blood sugar.
Stress: Stress hormones can increase blood sugar.
Illness: Infections can affect blood sugar control.
Hydration: Dehydration can lead to higher blood sugar concentrations.
Age: As we age, our bodies may become less efficient at regulating blood sugar.

How Age Impacts Blood Sugar Levels

As you age, several physiological changes can affect blood sugar levels:

Reduced Insulin Sensitivity: The body's cells may become less responsive to insulin, leading to insulin resistance.
Decreased Muscle Mass: Muscle tissue plays a role in glucose metabolism. Loss of muscle mass with age can impact blood sugar control.
Slower Metabolism: The metabolic rate tends to decline with age, potentially affecting blood sugar regulation.
Increased Risk of Other Health Conditions: Age increases the likelihood of developing other health issues that can impact blood sugar, such as cardiovascular disease and kidney problems.
Medication Interactions: Older adults are more likely to be taking multiple medications, increasing the risk of drug interactions that can affect blood sugar.

Due to these age-related changes, older adults may have slightly higher blood sugar targets than younger adults. It's crucial to work with your healthcare provider to establish appropriate blood sugar goals based on your individual circumstances and overall health status.

What to Do If Your Blood Sugar Is Too High or Too Low

If Your Blood Sugar Is Too High (Hyperglycemia):

Check Your Blood Sugar: Confirm the reading with a second test.
Hydrate: Drink plenty of water to help flush out excess glucose.
Exercise (If Appropriate): If you're able, engage in light physical activity like walking. Important: If you have ketones in your urine, avoid exercise until ketones are cleared. Check with your doctor.
Review Your Medication: If you take medication for diabetes, ensure you've taken the correct dose.
Contact Your Doctor: If your blood sugar remains high despite these measures, seek medical advice.

If Your Blood Sugar Is Too Low (Hypoglycemia):

Check Your Blood Sugar: Confirm the reading.
Eat or Drink Something Quickly: Consume 15-20 grams of fast-acting carbohydrates, such as glucose tablets, juice, regular soda, or hard candies.
Wait 15 Minutes and Recheck: After 15 minutes, recheck your blood sugar. If it's still low, repeat step 2.
Eat a Snack or Meal: Once your blood sugar is back in a normal range, eat a snack or meal to prevent it from dropping again.
Wear a Medical Alert: Consider wearing a medical alert bracelet or necklace to inform others of your condition in case of an emergency.
Contact Your Doctor: Discuss frequent episodes of hypoglycemia with your healthcare provider.

Tips for Maintaining Healthy Blood Sugar Levels

Follow a Balanced Diet: Emphasize whole grains, fruits, vegetables, lean protein, and healthy fats. Limit sugary drinks, processed foods, and refined carbohydrates.
Engage in Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week.
Monitor Your Blood Sugar Regularly: If you have diabetes, follow your doctor's recommendations for blood glucose monitoring.
Manage Stress: Practice stress-reduction techniques like yoga, meditation, or deep breathing exercises.
Get Enough Sleep: Aim for 7-8 hours of quality sleep per night.
Stay Hydrated: Drink plenty of water throughout the day.
Maintain a Healthy Weight: If you're overweight or obese, losing even a small amount of weight can improve blood sugar control.
Regular Medical Check-Ups: Schedule regular check-ups with your doctor to monitor your overall health and manage any underlying conditions.

The A1C Test: A Measure of Long-Term Blood Sugar Control

The A1C test, also known as the hemoglobin A1c test, provides an average of your blood sugar levels over the past 2-3 months. It's a valuable tool for diagnosing and managing diabetes.

Here's a general guide to A1C levels:

Normal: Below 5.7%
Prediabetes: 5.7% to 6.4%
Diabetes: 6.5% or higher

Like with blood sugar levels, target A1C levels may vary based on individual factors. Your doctor will help you determine your ideal A1C goal.
