The Ultimate Blood Sugar Levels Chart (By Age, Fasting & After Meals)
Understanding your blood sugar levels is crucial for maintaining good health, especially if you have diabetes or are at risk of developing it. This comprehensive guide provides a detailed blood sugar levels chart by age, fasting states, and after meals. Let's dive in!
Why Monitor Blood Sugar Levels?
Monitoring your blood sugar levels helps you and your healthcare provider understand how your body is responding to food, exercise, and medication. Keeping your blood sugar within a target range can help prevent long-term complications associated with high (hyperglycemia) or low (hypoglycemia) blood sugar. These complications can include nerve damage, kidney damage, heart disease, and vision problems.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels throughout the day, including:
- Food Intake: The type and amount of food you eat, particularly carbohydrates.
- Physical Activity: Exercise can lower blood sugar.
- Stress: Stress hormones can raise blood sugar.
- Medications: Certain medications can affect blood sugar levels.
- Underlying Health Conditions: Conditions such as infections can impact blood sugar.
- Sleep: Poor sleep can contribute to insulin resistance.
Blood Sugar Levels Chart by Age
While target ranges can vary based on individual health conditions and advice from your doctor, the following chart provides general guidelines for blood sugar levels by age. Keep in mind these are general guidelines, and you should consult your doctor for personalized recommendations.
| Age Group | Fasting Blood Sugar (mg/dL) | 2 Hours After Meal (mg/dL) | A1c Goal (%) |
|---|---|---|---|
| Children (6-12 years) | 80-180 | Up to 180 | Less than 8.0% |
| Teenagers (13-19 years) | 70-150 | Up to 140 | Less than 7.5% |

Fasting Blood Sugar Levels

Fasting blood sugar is the level of glucose in your blood after not eating for at least eight hours, usually measured first thing in the morning. Interpreting fasting blood sugar levels can help detect conditions such as prediabetes or diabetes.
| Category | Fasting Blood Sugar (mg/dL) | Interpretation |
|---|---|---|
| Normal | 70-99 | Healthy fasting blood sugar level. |
| Prediabetes | 100-125 | Indicates a higher risk of developing diabetes. Lifestyle changes are recommended. |
| Diabetes | 126 or higher | Consistent readings in this range may indicate diabetes. Consult a healthcare provider. |
Blood Sugar Levels After Meals (Postprandial)
Postprandial blood sugar refers to your blood glucose levels measured after eating. It is usually checked one to two hours after starting a meal. This measurement is important as it shows how well your body is processing the carbohydrates you've consumed.
