Your Complete Blood Sugar Levels Chart (By Age, Fasting & After Eating)
Understanding your blood sugar levels is crucial for managing your health, especially if you have diabetes or are at risk of developing it. This comprehensive guide breaks down the ideal blood sugar ranges for different age groups, fasting states, and post-meal measurements. We'll explore what these numbers mean, how they're measured, and what you can do to maintain healthy levels.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the primary source of energy for our bodies. It comes from the food we eat. The hormone insulin, produced by the pancreas, helps glucose move from the bloodstream into cells where it can be used for energy.
When you have diabetes, either your body doesn’t produce enough insulin (Type 1 diabetes) or your body doesn’t use insulin effectively (Type 2 diabetes). This leads to high blood sugar levels, known as hyperglycemia. Over time, persistently high blood sugar can damage organs, leading to serious health complications such as heart disease, kidney disease, nerve damage (neuropathy), and vision problems.
Conversely, low blood sugar, or hypoglycemia, can also be dangerous. Hypoglycemia can occur if you take too much insulin, skip meals, or exercise strenuously.
Therefore, monitoring your blood sugar levels is essential to prevent both hyperglycemia and hypoglycemia, ensuring optimal health.
Understanding Blood Sugar Measurements
Blood sugar levels are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). In the United States, mg/dL is the standard unit. Most of the ranges below are in mg/dL. To convert mg/dL to mmol/L, divide the mg/dL value by 18.
There are several ways to measure blood sugar, each providing different insights:
- Fasting Blood Sugar (FBS): This measures your blood sugar after an overnight fast (typically 8 hours). It's a common test used to screen for diabetes.
- Postprandial Blood Sugar (PPBS): This measures your blood sugar two hours after eating a meal. It helps determine how your body responds to food.
- A1C Test: This blood test provides an average of your blood sugar levels over the past 2-3 months. It's a key indicator of long-term blood sugar control.
- Random Blood Sugar Test: This test measures your blood sugar at any time of the day, without regard to when you last ate. It is typically used in individuals experiencing severe symptoms.
Blood Sugar Levels Chart By Age Group
Here's a breakdown of target blood sugar levels for different age groups. It's important to note that these are general guidelines, and your healthcare provider may recommend different targets based on your individual health profile.
Children and Adolescents

Maintaining healthy blood sugar levels is crucial for the proper growth and development of children and adolescents. Target ranges may vary slightly based on age and the presence of diabetes.
- Before Meals: 90-130 mg/dL
- After Meals (1-2 hours): Less than 180 mg/dL
- A1C Goal: Less than 7.5%
Adults (Non-Diabetic)
For adults without diabetes, the following ranges are considered normal:
- Fasting Blood Sugar: Less than 100 mg/dL
- Postprandial Blood Sugar (2 hours after eating): Less than 140 mg/dL
- A1C: Less than 5.7%
Adults with Diabetes
Managing blood sugar levels in adults with diabetes requires careful monitoring and control. Target ranges may vary depending on individual health conditions and treatment plans. Consult with a healthcare professional for personalized advice.

- A1C Goal: Less than 7% (This may be different for certain individuals.)
Seniors (65+)
Blood sugar goals for seniors often consider the presence of other health conditions and the risk of hypoglycemia. Less stringent targets might be appropriate for some individuals.
- Fasting Blood Sugar: 90-150 mg/dL
- Postprandial Blood Sugar (2 hours after eating): Less than 200 mg/dL
- A1C Goal: Less than 7.5% - 8.5% (Individualized based on overall health.)

How to Maintain Healthy Blood Sugar Levels
Maintaining stable blood sugar levels involves lifestyle adjustments and, in some cases, medication. Here are some key strategies:
- Eat a Balanced Diet: Focus on whole foods, including fruits, vegetables, lean proteins, and whole grains. Limit processed foods, sugary drinks, and excessive carbohydrates.
- Regular Exercise: Physical activity helps your body use insulin more effectively and can lower blood sugar levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Blood Sugar Regularly: If you have diabetes, check your blood sugar levels as recommended by your healthcare provider. Keep a log to track your levels and identify patterns.
- Medication: Follow your doctor's instructions regarding any medications prescribed to manage your blood sugar.
- Stay Hydrated: Drink plenty of water throughout the day to help your body function properly.
- Manage Stress: Stress can impact blood sugar levels. Practice relaxation techniques such as meditation, yoga, or deep breathing exercises.
- Get Enough Sleep: Adequate sleep is crucial for overall health and can affect blood sugar control.
Recognizing High and Low Blood Sugar Symptoms
Being able to recognize the symptoms of both high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia) is vital for managing your health effectively.
