Why Monitor Blood Sugar Levels?

Monitoring blood sugar levels is important for several reasons:

• Early Detection of Diabetes: Regular checks can help identify prediabetes or diabetes in its early stages.
• Management of Existing Diabetes: Helps individuals with diabetes manage their condition effectively.
• Prevention of Complications: Maintaining stable blood sugar can prevent long-term health problems associated with diabetes.
• General Health Awareness: Provides insights into how your body processes glucose and responds to food, exercise, and stress.

Understanding Blood Sugar Measurement Units

Before diving into the blood sugar levels chart, it’s crucial to understand the units of measurement:

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

You can convert between these units using the following formula:

• mg/dL = mmol/L x 18
• mmol/L = mg/dL / 18

Blood Sugar Levels Chart for Non-Diabetics

This chart outlines typical blood sugar ranges for individuals without diabetes. Keep in mind these are general guidelines, and slight variations can occur.

anxiety when blood sugar drops

Measurement Time	Target Range (mg/dL)	Target Range (mmol/L)
Fasting (After 8 hours of not eating)	70-99 mg/dL	3.9-5.5 mmol/L
1-2 Hours After Eating	Less than 140 mg/dL	Less than 7.8 mmol/L

Understanding the Numbers

• Fasting Blood Sugar: This is the blood sugar level measured after an overnight fast (typically 8 hours). It gives a baseline indication of how your body manages glucose when not actively processing food.
• Postprandial Blood Sugar: This refers to blood sugar levels measured 1-2 hours after eating. It reveals how well your body processes glucose from a meal.

Blood Sugar Levels Chart for Diabetics

For individuals with diabetes, the target blood sugar ranges are often different and depend on individual treatment plans. Here are general guidelines:

Measurement Time	Target Range (mg/dL)	Target Range (mmol/L)	Notes
Fasting	80-130 mg/dL	4.4-7.2 mmol/L	Individual goals may vary. Consult your doctor.
1-2 Hours After Eating	Less than 180 mg/dL	Less than 10.0 mmol/L	Again, individual goals should be discussed with a healthcare provider.

Importance of Individualized Goals

It’s essential to understand that these are general guidelines. Target blood sugar levels for individuals with diabetes may vary based on:

• Age
• Overall health
• Type of diabetes
• Presence of other health conditions
• Medications

Always work with your healthcare provider to establish personalized goals.

Blood Sugar Levels by Age

Blood sugar levels can also vary with age. Here’s a look at the typical ranges for different age groups.

Children

Measurement Time	Target Range (mg/dL)	Target Range (mmol/L)	Notes
Fasting (before meal)	70-150 mg/dL	3.9-8.3 mmol/L	Dependent on Age and Type of Diabetes (Type 1 or Type 2)
Before Meal (Age Specific)	Age <6 years: 100-180 mg/dL Age 6-12 years: 90-180 mg/dL Age 13-19 years: 90-130 mg/dL	Age <6 years: 5.5-10.0 mmol/L Age 6-12 years: 5.0-10.0 mmol/L Age 13-19 years: 5.0-7.2 mmol/L	Dependent on Age and Type of Diabetes (Type 1 or Type 2)
Bedtime	100-140 mg/dL	5.5-7.8 mmol/L	Dependent on Age and Type of Diabetes (Type 1 or Type 2)

Adults (60+)

For older adults, maintaining blood sugar levels within a specific range becomes more critical. These numbers factor in the presence of other health conditions and medications that may impact blood glucose control.

Measurement Time	Target Range (mg/dL)	Target Range (mmol/L)
Fasting	80-130 mg/dL	4.4-7.2 mmol/L
2 hours After Eating	Less than 180 mg/dL	Less than 10.0 mmol/L

Important Considerations for Older Adults:

• Increased risk of hypoglycemia (low blood sugar): Older adults are more susceptible to the adverse effects of low blood sugar, particularly if they have kidney or heart problems.
• Cognitive impairment: Both high and low blood sugar levels can impact cognitive function, making it crucial to maintain stable glucose levels.
• Medication interactions: The potential for drug interactions is higher among older adults, potentially affecting blood sugar levels.

What Happens When Blood Sugar Levels Are Too High (Hyperglycemia)?

Hyperglycemia occurs when blood sugar levels are elevated. Symptoms can include:

• Increased thirst
• Frequent urination
• Blurred vision
• Fatigue
• Headaches

Long-Term Risks of Hyperglycemia

Uncontrolled hyperglycemia can lead to serious complications, including:

• Heart disease
• Kidney disease
• Nerve damage (neuropathy)
• Eye damage (retinopathy)

What to Do If You Have Hyperglycemia

• Check your blood sugar more frequently.
• Adjust your medication, if applicable, as directed by your healthcare provider.
• Drink plenty of water to stay hydrated.
• Engage in light exercise, if appropriate.
• Contact your doctor if your blood sugar remains high despite these measures.

What Happens When Blood Sugar Levels Are Too Low (Hypoglycemia)?

Hypoglycemia occurs when blood sugar levels drop too low. Symptoms can include:

• Shakiness
• Sweating
• Dizziness
• Confusion
• Rapid heartbeat
• Hunger

Risks of Hypoglycemia

Hypoglycemia can be dangerous if left untreated and can lead to:

• Loss of consciousness
• Seizures
• Coma

What to Do If You Have Hypoglycemia

• Follow the 15-15 rule: Consume 15 grams of fast-acting carbohydrates (e.g., glucose tablets, fruit juice, or regular soda) and check your blood sugar levels after 15 minutes. Repeat if your blood sugar is still low.
• Once your blood sugar is back to normal, have a snack containing both carbohydrates and protein (e.g., crackers with peanut butter) to stabilize your levels.
• Carry a source of fast-acting glucose with you at all times, especially if you have diabetes.
