What is Blood Sugar and Why is it Important?
Blood sugar, also known as blood glucose, is the main sugar found in your blood. It comes from the food you eat and is your body's primary source of energy. Your pancreas produces insulin, a hormone that helps glucose from food get into your cells to be used for energy.
Maintaining proper blood sugar levels is essential because:
- Energy Production: Glucose fuels your cells, allowing your body to function properly.
- Organ Function: Consistent blood sugar levels support healthy organ function, particularly for the brain and kidneys.
- Disease Prevention: Keeping your blood sugar within the normal range reduces the risk of developing diabetes, heart disease, and other related complications.

Before diving into the ranges, it's important to understand the different types of blood sugar tests and their meanings:
- Fasting Blood Sugar (FBS): This test measures your blood sugar after an overnight fast (at least 8 hours).
- Postprandial Blood Sugar (PPBS): This test measures your blood sugar 2 hours after starting a meal.
- HbA1c (Glycated Hemoglobin): This test provides an average of your blood sugar levels over the past 2-3 months.
- Random Blood Sugar: This test measures your blood sugar at any time of day, regardless of when you last ate.
Normal Blood Sugar Ranges by Age Group
Blood sugar ranges can vary slightly depending on age and individual health conditions. However, here’s a general guideline:
Children
| Test | Normal Range (mg/dL) |
|---|---|
| Fasting Blood Sugar | 70-100 |
| Postprandial Blood Sugar (2 hours after eating) | Less than 140 |
| HbA1c | Less than 5.7% |

Adults (Under 60)
| Test | Normal Range (mg/dL) |
|---|---|
| Fasting Blood Sugar | 70-99 |
| Postprandial Blood Sugar (2 hours after eating) | Less than 140 |
| HbA1c | Less than 5.7% |
Adults (60 and Older)
For older adults, slightly higher blood sugar levels might be considered acceptable, depending on individual health status and other factors.
| Test | Normal Range (mg/dL) |
|---|---|
| Fasting Blood Sugar | 80-115 |
| Postprandial Blood Sugar (2 hours after eating) | Less than 160 |
| HbA1c | Less than 7.0% (Consult doctor) |
Important: These are general guidelines. Talk to your healthcare provider for personalized recommendations based on your overall health and medical history.
What Happens When Blood Sugar Levels are Too High (Hyperglycemia)?
Hyperglycemia occurs when your blood sugar levels are consistently elevated. Symptoms may include:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
If left untreated, chronic hyperglycemia can lead to serious complications, including:
- Nerve damage (neuropathy)
- Kidney damage (nephropathy)
- Eye damage (retinopathy)
- Cardiovascular disease
How to Manage High Blood Sugar
- Consult Your Doctor: Regular check-ups are crucial for monitoring your condition and adjusting treatment plans if necessary.
- Medication: Follow your doctor's prescribed medication regimen, which may include insulin or oral medications.
- Dietary Changes: Adopt a diabetes-friendly diet. Limit sugary drinks, processed foods, and excessive carbohydrates. Focus on whole grains, lean proteins, and plenty of fruits and vegetables.
- Regular Exercise: Physical activity helps lower blood sugar levels by improving insulin sensitivity.
- Monitor Blood Sugar Regularly: Use a blood glucose meter to monitor your blood sugar levels as recommended by your healthcare provider.
What Happens When Blood Sugar Levels are Too Low (Hypoglycemia)?
Hypoglycemia occurs when your blood sugar levels drop too low. Symptoms may include:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Rapid heartbeat
Severe hypoglycemia can lead to loss of consciousness or seizures.
How to Manage Low Blood Sugar
- The 15-15 Rule: If your blood sugar is low, eat 15 grams of fast-acting carbohydrates (like glucose tablets, juice, or regular soda), wait 15 minutes, and then recheck your blood sugar. Repeat as needed until your blood sugar is above 70 mg/dL.
- Medical ID: Wear a medical ID bracelet or carry a card indicating that you have diabetes in case of emergency.
- Meal Planning: Eat regular, balanced meals and snacks to prevent blood sugar dips.
- Consult Your Doctor: Discuss frequent hypoglycemia episodes with your doctor to adjust your diabetes management plan.
How to Monitor Your Blood Sugar Levels
Blood Glucose Meters
A blood glucose meter is a portable device used to measure the amount of glucose in your blood.
- Prick your finger: Use a lancet to prick the side of your finger.
- Apply blood to test strip: Gently squeeze a drop of blood onto the test strip.
- Insert test strip into meter: The meter will display your blood sugar reading within seconds.
- Record your results: Keep a log of your readings to share with your doctor.
Continuous Glucose Monitoring (CGM)
A CGM is a device that continuously tracks your blood glucose levels throughout the day and night. It consists of a small sensor inserted under the skin that measures glucose levels in the interstitial fluid.
- Provides real-time blood sugar readings.
- Alerts you when your blood sugar is too high or too low.
- Helps you identify patterns and trends in your blood sugar levels.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels:
- Diet: The type and amount of carbohydrates you consume have a direct impact on blood sugar.
- Exercise: Physical activity can lower blood sugar levels by improving insulin sensitivity.
- Stress: Stress hormones can raise blood sugar.
- Illness: Infections and illnesses can affect blood sugar control.
- Medications: Certain medications, such as steroids, can increase blood sugar levels.
- Hydration: Dehydration can concentrate blood sugar, leading to higher readings.
Tips for Maintaining Healthy Blood Sugar Levels
- Eat a Balanced Diet: Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. Limit sugary drinks, processed foods, and refined carbohydrates.
- Stay Active: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Maintain a Healthy Weight: Losing even a small amount of weight can improve insulin sensitivity and blood sugar control.
- Get Enough Sleep: Lack of sleep can affect blood sugar levels and insulin resistance.
- Manage Stress: Practice stress-reduction techniques like meditation, yoga, or deep breathing.
- Stay Hydrated: Drink plenty of water throughout the day to keep your blood sugar from becoming too concentrated.
- Monitor Blood Sugar Regularly: Check your blood sugar as recommended by your healthcare provider.
- Regular Check-ups: Keep appointments with your doctor and diabetes educator for ongoing care and support.
When to See a Doctor
It's important to consult a healthcare professional if:
- You experience frequent symptoms of high or low blood sugar.
- You have consistently high or low blood sugar readings.
- You have risk factors for diabetes, such as family history, obesity, or high blood pressure.
- You are pregnant or planning to become pregnant.
