The Ultimate Blood Sugar Levels Chart by Age (mg/dL & mmol/L)
Understanding your blood sugar levels is crucial for maintaining good health, especially if you have diabetes or are at risk. This article provides a comprehensive blood sugar levels chart by age, covering both mg/dL and mmol/L measurements. We'll explore target ranges, what constitutes high or low blood sugar, and how to manage your glucose levels effectively. Let's dive in! Blood Sugar Mg Dl To Mmol L An Easy Conversion Chart
Why Blood Sugar Levels Matter
Your blood sugar, or glucose, is the primary source of energy for your body. Maintaining stable blood sugar levels is essential for proper organ function and overall well-being. When blood sugar levels are too high (hyperglycemia) or too low (hypoglycemia), it can lead to a variety of health problems. For individuals with diabetes, regular monitoring and management of blood sugar is paramount. Impaired Fasting Glucose What It Means And Your Next Steps
Understanding the Units: mg/dL vs. mmol/L
Blood sugar levels are typically measured in two units:
- mg/dL (milligrams per deciliter): This is the standard unit used in the United States.
- mmol/L (millimoles per liter): This is the unit used in many other parts of the world.
To convert from mg/dL to mmol/L, divide the mg/dL value by 18. For example, 100 mg/dL is approximately equal to 5.6 mmol/L.
Blood Sugar Levels Chart by Age (mg/dL & mmol/L)
This chart provides general guidelines. Individual targets may vary based on specific health conditions and recommendations from your healthcare provider. Always consult your doctor for personalized advice.
Age Group | Fasting Blood Sugar (mg/dL) | Fasting Blood Sugar (mmol/L) | 2-Hour Postprandial (After Meal) (mg/dL) | 2-Hour Postprandial (After Meal) (mmol/L) | HbA1c (Target) |
---|---|---|---|---|---|
Children (Under 6) | 80-200 | 4.4-11.1 | Up to 200 | Up to 11.1 | 6.0-8.5% |
Children (6-12) | 80-180 | 4.4-10.0 | Up to 180 | Up to 10.0 | 6.0-8.0% |
Teens (13-19) | 70-150 | 3.9-8.3 | Up to 140 | Up to 7.8 | 6.0-7.5% |
Adults (20+) - Non-Diabetic | 70-99 | 3.9-5.5 | Less than 140 | Less than 7.8 | Less than 5.7% |
Adults (20+) - Diabetic | 80-130 | 4.4-7.2 | Less than 180 | Less than 10.0 | Less than 7.0% (Individual target may vary) |
Elderly (65+) - Diabetic | 80-150 | 4.4-8.3 | Less than 200 | Less than 11.1 | Less than 7.5% (Individual target may vary) |
Important Notes:
- Fasting Blood Sugar: Measured after at least 8 hours of fasting.
- 2-Hour Postprandial: Measured 2 hours after the start of a meal.
- HbA1c: Represents your average blood sugar level over the past 2-3 months. It's expressed as a percentage.
- Individual Targets: The target blood sugar ranges can vary significantly based on individual health status, age, other medical conditions, and treatment plans. It is essential to work with your healthcare provider to determine your ideal range.
Understanding High Blood Sugar (Hyperglycemia)
Hyperglycemia occurs when your blood sugar levels are too high. Symptoms can include:
- Frequent urination
- Increased thirst
- Blurred vision
- Fatigue
- Slow-healing sores
Prolonged high blood sugar can lead to serious complications like nerve damage (neuropathy), kidney damage (nephropathy), and cardiovascular disease. The Senior S Guide To A Safe And Healthy A1C Level
Understanding Low Blood Sugar (Hypoglycemia)
Hypoglycemia occurs when your blood sugar levels are too low. Symptoms can include:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Hunger
Severe low blood sugar can lead to loss of consciousness and seizures.
Factors Affecting Blood Sugar Levels
Many factors can influence your blood sugar levels, including:
- Diet: The type and amount of food you eat significantly impacts blood sugar. High-carb foods tend to raise blood sugar more quickly.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity and using glucose for energy.
- Medications: Certain medications, including insulin and oral diabetes medications, directly affect blood sugar. Other medications can also indirectly influence glucose levels.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and other illnesses can impact blood sugar.
- Sleep: Poor sleep can affect insulin sensitivity and lead to fluctuations in blood sugar.
- Dehydration: Dehydration can concentrate the glucose in your blood, leading to higher readings.
- Menstrual Cycle: Hormonal changes during the menstrual cycle can impact blood sugar in women.
Tips for Managing Blood Sugar Levels
Here are some practical tips for managing your blood sugar levels effectively:

- Follow a Balanced Diet: Focus on whole foods, including fruits, vegetables, lean proteins, and whole grains. Limit processed foods, sugary drinks, and refined carbohydrates.
- Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Monitor Your Blood Sugar Regularly: Use a blood glucose meter to check your levels at home. Your doctor will advise on how often you should test. Consider a continuous glucose monitor (CGM) for real-time tracking.
- Take Medications as Prescribed: If you have diabetes, follow your doctor's instructions for taking insulin or other diabetes medications.
- Manage Stress: Practice stress-reduction techniques like yoga, meditation, or deep breathing exercises.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Stay Hydrated: Drink plenty of water throughout the day.
- Work with a Healthcare Professional: Consult with your doctor, a registered dietitian, or a certified diabetes educator to develop a personalized management plan.
- Learn to Count Carbs: Accurately counting carbs will allow for better insulin management.
- Keep a Log: Track your blood sugar, food intake, and exercise for insight and to share with your healthcare team.
When to Seek Medical Attention
Seek immediate medical attention if you experience any of the following:
- Very high blood sugar (e.g., above 300 mg/dL or 16.7 mmol/L) that doesn't respond to treatment.
- Severe low blood sugar (e.g., below 70 mg/dL or 3.9 mmol/L), especially if you are unable to treat it yourself or if you lose consciousness.
- Symptoms of diabetic ketoacidosis (DKA), such as nausea, vomiting, abdominal pain, and fruity-smelling breath.
- Symptoms of hyperosmolar hyperglycemic state (HHS), such as severe dehydration, confusion, and seizures.
Conclusion
Understanding and managing your blood sugar levels is crucial for your overall health and well-being. Use this blood sugar levels chart by age as a general guide, but always consult with your healthcare provider for personalized advice and treatment. By adopting healthy lifestyle habits and closely monitoring your blood sugar, you can maintain stable glucose levels and prevent potential complications.
