Normal Blood Sugar Ranges by Age and Type

Here's a breakdown of typical blood sugar ranges. Please note these are general guidelines, and individual targets may vary. Consult with your healthcare provider for personalized recommendations.

  • Fasting Blood Sugar (Before a Meal):
    • For People Without Diabetes: 70-99 mg/dL (3.9-5.5 mmol/L)
    • For People with Diabetes (Target Range): 80-130 mg/dL (4.4-7.2 mmol/L) – as determined by their doctor.
  • 2 Hours After Eating (Postprandial):
    • For People Without Diabetes: Less than 140 mg/dL (7.8 mmol/L)
    • For People with Diabetes (Target Range): Less than 180 mg/dL (10 mmol/L) – as determined by their doctor.
  • A1C (Average Blood Sugar Over 2-3 Months):
    • For People Without Diabetes: Below 5.7%
    • For People with Diabetes (Target Range): Below 7% – as determined by their doctor. Some individuals may have different targets.

Factors Affecting Your Blood Sugar Levels

You meticulously track your diet and exercise, yet your blood sugar level still behaves unpredictably. Here are some surprising factors:

  • Sleep Quality: Just one night of poor sleep can disrupt hormones and decrease insulin sensitivity.
  • Daily Stress: Your body's "fight-or-flight" response triggers hormone release that elevates blood sugar.
  • Hydration Status: Dehydration can impact blood sugar levels.
  • Hormonal Shifts: Subtle hormonal changes can influence glucose metabolism.
  • Medications: Certain medications can affect blood sugar.
  • Illness: Even a common cold can temporarily elevate glucose levels.

How to Check Your Blood Sugar Level Accurately

The number on your meter isn't just data; it's the foundation for every decision you make. This guide covers the subtle details that ensure a reliable reading:

  • Hand Washing: Thoroughly wash and dry your hands.
  • Test Strip Handling: Follow instructions carefully for handling test strips.
  • Blood Sample: Ensure you get a sufficient blood sample.
  • Meter Calibration: Regularly calibrate your meter.

The Role of Diet in Blood Sugar Management

Mastering the relationship between what you eat and your metabolic health is the most powerful step you can take.

  • Carbohydrate Awareness: Understand how different carbs impact your blood sugar.
  • Glycemic Index (GI): Learn about foods with a high or low GI.
  • Fiber Intake: Increase your intake of fiber-rich foods.
  • Meal Timing & Portion Control: Plan your meals and control portion sizes.

Exercise and Blood Sugar

Unlock the potent connection between physical activity and your metabolic health. Exercise acts like a key, helping your muscles absorb glucose and improving insulin sensitivity.

Decoding Your Blood Sugar Reading: What the Numbers Mean

That number staring back at you from the glucose meter is more than just a digit. It's a piece of a larger puzzle about your health. Learn the difference between a fasting reading, a post-meal result, and where your number falls within your target range.

The Dangers of Uncontrolled Blood Sugar Levels

The consequences of persistently high or erratic blood sugar extend far beyond a single reading. Understanding these risks provides motivation to protect your future health.
