Normal Blood Sugar Levels Chart by Age: What’s Your Target Range?

Understanding your blood sugar levels is essential for maintaining good health, regardless of age. But what’s considered "normal" can actually vary depending on your age group and individual health conditions. This article provides a comprehensive normal blood sugar levels chart by age, explains the factors affecting those levels, and offers valuable insights for managing your blood glucose effectively.

Why Blood Sugar Levels Matter

Blood sugar, also known as blood glucose, is the main sugar found in your blood. It comes from the food you eat and is your body's primary source of energy. Maintaining stable blood sugar levels is crucial because:

  • Energy Supply: Your cells need glucose for energy.
  • Organ Function: High or low blood sugar can damage organs.
  • Diabetes Prevention: Monitoring helps prevent or manage diabetes.
  • Overall Health: Keeping your blood sugar in a healthy range contributes to overall well-being.

Normal Blood Sugar Levels Chart by Age

The following chart outlines generally accepted normal blood sugar levels by age. It's important to consult with your doctor for personalized targets, especially if you have diabetes or other health conditions. Remember that these are general guidelines and individual targets may vary based on your doctor's recommendations.

Age Group Fasting Blood Sugar (mg/dL) 2 Hours After Eating (mg/dL) A1C (%)
Children (Under 6) 80-180 Up to 200 N/A
Children (6-12) 80-120 Up to 140 N/A
Teenagers (13-19) 70-150 Up to 140 N/A
Adults (20+) Without Diabetes 70-99 Less than 140 Less than 5.7%
Adults (20+) With Diabetes 80-130 Less than 180 Less than 7% (as advised by doctor)
Seniors (65+) Without Diabetes 70-100 Less than 140 Less than 6.5%
Seniors (65+) With Diabetes 90-150 Less than 200 Less than 8% (as advised by doctor)

Note: These are general guidelines. Individual targets may vary based on your doctor's recommendations and health condition.

Understanding Blood Sugar Measurements

  • Fasting Blood Sugar: This is your blood sugar level after not eating or drinking for at least eight hours. It's often measured first thing in the morning. A normal fasting blood sugar level is generally between 70 and 99 mg/dL.
  • 2 Hours After Eating: This measures your blood sugar two hours after you start eating a meal. It's a good indicator of how your body processes glucose. For people without diabetes, a normal level is usually less than 140 mg/dL.
  • A1C: The A1C test provides an average of your blood sugar levels over the past 2-3 months. It's a more long-term measure of blood sugar control. For people without diabetes, a normal A1C level is below 5.7%.

Factors Influencing Blood Sugar Levels

Numerous factors can affect your blood sugar levels, including:

  • Diet: The types and amounts of food you eat significantly impact your blood sugar. High-carbohydrate and sugary foods can cause spikes.
  • Physical Activity: Exercise helps your body use glucose for energy, lowering blood sugar levels. Inactivity can lead to higher levels.
  • Stress: Stress hormones can raise blood sugar levels.
  • Medications: Certain medications, like steroids, can affect blood sugar.
  • Medical Conditions: Conditions like infections or illnesses can temporarily raise blood sugar.
  • Age: As you age, your body's ability to regulate blood sugar may decline.
  • Genetics: Family history can play a role in your susceptibility to diabetes and blood sugar issues.
  • Sleep: Lack of sleep or poor sleep quality can impact blood sugar regulation.

Tips for Maintaining Healthy Blood Sugar Levels

Here are some practical steps you can take to help keep your blood sugar within a healthy range:

  1. Eat a Balanced Diet: Focus on whole grains, lean protein, and plenty of fruits and vegetables. Limit sugary drinks and processed foods.
  2. Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
  3. Monitor Your Blood Sugar: If you have diabetes or are at risk, regularly check your blood sugar levels as recommended by your doctor.
  4. Stay Hydrated: Drinking plenty of water helps your body function properly and can impact blood sugar.
  5. Manage Stress: Practice relaxation techniques like yoga, meditation, or deep breathing exercises.
  6. Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
  7. Take Medications as Prescribed: If you have diabetes, follow your doctor's instructions for medication management.
  8. Regular Check-ups: See your doctor regularly for check-ups and screenings, especially if you have a family history of diabetes.

When to See a Doctor

It's important to consult a doctor if you experience any of the following symptoms, which could indicate high or low blood sugar:

  • Frequent urination
  • Excessive thirst
  • Unexplained weight loss
  • Increased hunger
  • Blurred vision
  • Slow-healing sores
  • Frequent infections
  • Fatigue
  • Irritability

If you are experiencing symptoms of hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar), it’s critical to seek immediate medical attention, especially if you are a diabetic.
