The Complete Blood Sugar Levels Chart: What's Normal by Age?
Understanding blood sugar levels is crucial for maintaining good health, especially for those at risk of or living with diabetes. This article provides a comprehensive blood sugar levels chart that outlines normal ranges by age, factors affecting these levels, and what you can do to maintain healthy glucose levels.
Why is Monitoring Blood Sugar Important?
Monitoring blood sugar helps individuals manage diabetes, prevent complications, and make informed decisions about their diet and lifestyle. Maintaining stable blood glucose levels helps prevent long-term health issues affecting the heart, kidneys, eyes, and nerves.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood glucose levels. These include:
- Diet: The types and amount of carbohydrates you consume directly affect blood sugar.
- Physical Activity: Exercise can lower blood sugar levels as your body uses glucose for energy.
- Stress: Stress hormones can increase blood sugar levels.
- Medications: Certain medications, like steroids, can raise blood sugar.
- Illness: Infections can lead to elevated glucose levels.
- Age: Normal blood sugar ranges can vary slightly based on age.
- Time of Day: Blood sugar naturally fluctuates throughout the day.
Blood Sugar Levels Chart by Age
The following table provides general guidelines for normal blood sugar ranges. These numbers can vary slightly based on individual health conditions and recommendations from your healthcare provider. Always consult your doctor for personalized advice.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Meal (mg/dL) | A1C (%) |
|---|---|---|---|
| Children (Under 6) | 80-180 | Up to 200 | N/A (Targets vary based on individual factors and doctor's recommendations) |
| Children (6-12) | 80-120 | Up to 140 | N/A (Targets vary based on individual factors and doctor's recommendations) |
| Teenagers (13-19) | 70-150 | Up to 140 | N/A (Targets vary based on individual factors and doctor's recommendations) |
| Adults (20+) Non-Diabetic | 70-99 | Less than 140 | Less than 5.7% |
| Adults (20+) Diabetic | 80-130 | Less than 180 | Less than 7.0% (Target varies depending on individual factors) |
| Older Adults (65+) | 80-180 (Targets may be less strict) | Less than 200 (Targets may be less strict) | Less than 7.5% (Target varies depending on individual factors) |
Important Notes:
- Fasting Blood Sugar: Measured after at least 8 hours of fasting.
- 2 Hours After Meal: Measured 2 hours after the start of a meal.
- A1C: Represents the average blood sugar level over the past 2-3 months. This is not a daily reading, but rather a summary. The ADA (American Diabetes Association) recommendation for many adults with diabetes is an A1C of less than 7%. Target A1C values must be individualized and determined by your medical provider. Higher or lower goals may be appropriate depending on several individual factors.
What to Do if Your Blood Sugar is High
