The Complete Blood Sugar Levels Chart by Age (For Diabetics & Non-Diabetics)

Understanding blood sugar levels is crucial for maintaining good health, regardless of whether you have diabetes or not. This comprehensive guide provides a blood sugar levels chart by age, offering valuable insights for both diabetics and non-diabetics. We'll cover what's considered normal, what to do if your blood sugar is too high or too low, and the importance of regular monitoring. Let's dive in!

Why Blood Sugar Levels Matter

Your blood glucose, or blood sugar, comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. When you have diabetes, your body either doesn't make enough insulin or can't effectively use the insulin it does make. This leads to elevated blood sugar levels, which can damage organs and tissues over time. Maintaining optimal blood sugar levels is therefore vital to prevent complications. Even for non-diabetics, consistently high or low blood sugar can indicate underlying health issues or predispose one to developing diabetes later in life.

Understanding Blood Sugar Readings

Before jumping into the chart, let's clarify the measurements used for blood sugar:

mg/dL (milligrams per deciliter): This is the standard unit used in the United States.
mmol/L (millimoles per liter): This unit is used in many other countries.

This article will primarily use mg/dL, but will also include mmol/L for those who prefer that measurement.

Also, understand what each reading typically represents:

Fasting Blood Sugar: Measured after at least eight hours of fasting (no food or drinks other than water).
Postprandial Blood Sugar: Measured 1-2 hours after eating a meal.
A1C (Hemoglobin A1c): This test provides an average of your blood sugar control over the past 2-3 months.

Blood Sugar Levels Chart by Age (mg/dL & mmol/L)

This table provides general guidelines, and individual targets might vary based on specific health conditions and doctor recommendations. Always consult with your healthcare provider for personalized advice.

Age Group	Condition	Fasting Blood Sugar (mg/dL)	Fasting Blood Sugar (mmol/L)	Postprandial Blood Sugar (1-2 hrs after eating) (mg/dL)	Postprandial Blood Sugar (1-2 hrs after eating) (mmol/L)	A1C
Children (Under 6)	Non-Diabetic	80-180	4.4-10.0	Up to 200	Up to 11.1	N/A
Children (Under 6)	Diabetic	80-200	4.4-11.1	Up to 200	Up to 11.1	Below 8.5% (Goal is individualized)
Children (6-12)	Non-Diabetic	70-130	3.9-7.2	Up to 140	Up to 7.8	N/A
Children (6-12)	Diabetic	70-150	3.9-8.3	Up to 180	Up to 10.0	Below 8% (Goal is individualized)
Teens (13-19)	Non-Diabetic	70-130	3.9-7.2	Up to 140	Up to 7.8	N/A

Adults (20+)	Diabetic	80-130	4.4-7.2	Up to 180	Up to 10.0	Below 7% (Goal is individualized)
Older Adults (65+)	Non-Diabetic	70-99	3.9-5.5	Up to 140	Up to 7.8	Below 5.7%
Older Adults (65+)	Diabetic	80-150	4.4-8.3	Up to 200	Up to 11.1	Below 7.5% - 8.5% (Goal is individualized)

Note: This chart serves as a general guideline. Consult your healthcare provider for personalized blood sugar targets.

What If Your Blood Sugar Is Too High? (Hyperglycemia)

Hyperglycemia occurs when your blood sugar levels are higher than your target range. Symptoms can include:

Frequent urination
Increased thirst
Blurred vision
Fatigue
Headache

What to do:

Check your blood sugar: Confirm the high reading.
Drink water: Stay hydrated to help flush out excess sugar.
Exercise (if appropriate): Physical activity can lower blood sugar, but avoid exercise if you have ketones in your urine. Always consult your doctor.
Adjust medication (if prescribed): If you take insulin or oral diabetes medications, follow your doctor's instructions for adjusting your dosage.
Contact your doctor: If your blood sugar remains high despite your efforts, seek medical advice.

Untreated hyperglycemia can lead to serious complications such as diabetic ketoacidosis (DKA) or hyperglycemic hyperosmolar state (HHS), both of which require immediate medical attention.

What If Your Blood Sugar Is Too Low? (Hypoglycemia)

Hypoglycemia occurs when your blood sugar levels are lower than your target range. Symptoms can include:

Shakiness
Sweating
Dizziness
Confusion
Rapid heartbeat
Hunger
Irritability

What to do:

Check your blood sugar: Confirm the low reading.
Follow the "15-15 Rule": Consume 15 grams of fast-acting carbohydrates (e.g., glucose tablets, juice, regular soda).
Wait 15 minutes: Recheck your blood sugar after 15 minutes.
Repeat if necessary: If your blood sugar is still low, repeat the 15-15 rule.
Eat a meal or snack: Once your blood sugar is back to normal, eat a meal or snack to prevent it from dropping again.
Contact your doctor: If you experience frequent episodes of hypoglycemia, discuss with your doctor to adjust your treatment plan.

Severe hypoglycemia can lead to loss of consciousness, seizures, and coma, so it's crucial to treat it promptly.

Monitoring Blood Sugar: A Key Component of Management

Regular blood sugar monitoring is essential for managing diabetes and maintaining overall health. This can be done using:

Blood Glucose Meter: A small device that tests a drop of blood, usually from a fingertip.
Continuous Glucose Monitor (CGM): A device that continuously tracks blood glucose levels through a sensor inserted under the skin. CGMs provide real-time data and can alert you to trends and patterns.

Frequency of monitoring:

Non-diabetics: May only need occasional checks, especially if they have risk factors for diabetes.
Diabetics: Frequency varies based on the type of diabetes, treatment plan, and individual needs. Some may need to check several times a day.

Factors Affecting Blood Sugar Levels

Numerous factors can influence your blood sugar levels:

Food: Type, amount, and timing of meals and snacks.
Physical Activity: Exercise lowers blood sugar.
Medications: Insulin and other diabetes medications.
Stress: Stress hormones can raise blood sugar.
Illness: Infections and other illnesses can affect blood sugar.
Dehydration: Can increase blood sugar concentration.
Menstrual Cycle: Hormonal changes can impact blood sugar in women.
Alcohol: Can initially raise blood sugar, but can subsequently cause it to drop, especially if consumed on an empty stomach.

Tips for Maintaining Healthy Blood Sugar Levels

Eat a balanced diet: Focus on whole grains, fruits, vegetables, lean protein, and healthy fats.
Control portion sizes: Be mindful of how much you're eating.
Exercise regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
Manage stress: Practice relaxation techniques such as yoga, meditation, or deep breathing.
Stay hydrated: Drink plenty of water throughout the day.
Get enough sleep: Aim for 7-8 hours of sleep per night.
Monitor your blood sugar regularly: Follow your doctor's recommendations for blood sugar testing.
Work with a healthcare professional: A doctor or registered dietitian can help you develop a personalized plan to manage your blood sugar levels.

The Importance of a Healthy Lifestyle

In conclusion, maintaining optimal blood sugar levels is key for both diabetics and non-diabetics alike. By understanding the blood sugar levels chart by age, and implementing lifestyle changes like a balanced diet, regular exercise, and stress management, you can effectively control your blood sugar and promote overall well-being. Remember to always consult your healthcare provider for personalized advice and management strategies. Regular blood sugar monitoring combined with medical guidance are essential components for long-term health and disease prevention.
