Understanding what constitutes normal blood sugar levels is the foundation of glucose management. These values vary depending on when you last ate and other factors.

Blood Sugar Ranges

Condition	Glucose Level (mg/dL)	Glucose Level (mmol/L)	Recommendations
Normal fasting blood sugar	70-99 mg/dL	3.9-5.5 mmol/L	Ideal range for metabolic health
Normal before meals	70-99 mg/dL	3.9-5.5 mmol/L	Target for most individuals
Normal 2 hours after eating	Less than 140 mg/dL	Less than 7.8 mmol/L	Indicates good glucose processing
Prediabetes (fasting)	100-125 mg/dL	5.6-6.9 mmol/L	Lifestyle changes recommended
Diabetes (fasting)	126 mg/dL or higher	7.0 mmol/L or higher	Medical intervention needed

Understanding Your Numbers

It’s important to note that target ranges may vary slightly depending on age, medical history, and other health conditions. Your healthcare provider can help you determine the optimal target range for your specific situation.

Consistently monitoring your levels and understanding what the numbers mean is key to effective diabetes management and prevention.

Regular monitoring of blood glucose levels is essential for effective diabetes management. It helps you understand how food, activity, medication, and other factors affect your blood sugar.

Monitoring Methods

• Fingerstick testing – Traditional method using a glucose meter and test strips. Provides a snapshot of your blood sugar at a specific moment.
• Continuous Glucose Monitoring (CGM) – Sensors that measure glucose throughout the day. Provides real-time data and trends.
• HbA1c test – Laboratory test measuring average blood sugar over 2-3 months. Goal for most diabetics is below 7%.
• Flash glucose monitoring – Scanning sensor for on-demand readings without fingersticks.
• Urine glucose tests – Less common now but can detect high glucose levels.

Testing Frequency

The frequency of testing depends on your type of diabetes, treatment plan, and overall health stability. People with type 1 diabetes typically need to test more frequently than those with type 2 diabetes. Your healthcare provider will recommend a testing schedule tailored to your needs.

Keeping Records

Maintaining a log of your blood sugar readings, along with notes about food, activity, medication, and how you feel, can help identify patterns and guide treatment adjustments. Many modern glucose meters and apps can automatically track and analyze this data.

Effective blood sugar management involves a combination of lifestyle modifications, medication (if prescribed), and regular monitoring. A holistic approach yields the best results for long-term health.

Dietary Strategies

• Carbohydrate counting – Managing intake of carbs which directly affect blood sugar. Work with a dietitian to determine your ideal daily carbohydrate intake.
• Choose high-fiber foods – Slows glucose absorption. Aim for 25-30 grams of fiber daily from vegetables, fruits, and whole grains.
• Portion control – Managing serving sizes to prevent spikes. Use measuring cups or a food scale until you can estimate portions accurately.
• Regular meal timing – Helps maintain consistent glucose levels. Try to eat at similar times each day.
• Limit sugary foods and drinks – Reduces rapid glucose spikes. Choose water, unsweetened tea, or coffee instead of sugary beverages.

Blood Sugar Friendly Foods

Physical Activity

Regular exercise helps your body use insulin more efficiently and can lower blood sugar levels. Aim for at least 150 minutes of moderate-intensity aerobic activity per week, along with strength training exercises twice a week. Always check your blood sugar before and after exercise, especially if you take insulin or medications that can cause hypoglycemia.

Medication Management

If lifestyle changes aren’t enough to manage your blood sugar, your doctor may prescribe medication. These may include oral medications, injectable medications, or insulin therapy. It’s crucial to take medications as prescribed and communicate with your healthcare team about any side effects or concerns.

Consistently high blood sugar levels can lead to serious health complications over time. Understanding these risks can motivate consistent management and prevention efforts.

Long-Term Complications

• Cardiovascular disease – Increased risk of heart attack, stroke, and hypertension. Diabetes doubles the risk of heart disease.
• Nerve damage (neuropathy) – Tingling, numbness, or pain in extremities. About half of people with diabetes have some form of nerve damage.
• Kidney damage (nephropathy) – Can lead to kidney failure. Diabetes is the leading cause of kidney failure.
• Eye damage (retinopathy) – Potential for blindness. Diabetes is the leading cause of new cases of blindness in adults.
• Foot damage – Poor blood flow and nerve damage increase infection risk. Severe cases may lead to toe, foot, or leg amputation.
• Skin conditions – Increased susceptibility to bacterial and fungal infections.
• Alzheimer’s disease – Type 2 diabetes may increase the risk of dementia and Alzheimer’s disease.

Hypoglycemia Risks

While high blood sugar causes long-term complications, low blood sugar (hypoglycemia) can cause immediate dangerous situations including confusion, seizures, and loss of consciousness. It’s important to recognize the signs of low blood sugar and know how to treat it quickly.

Prevention Strategies

The good news is that many diabetes complications can be prevented or delayed through consistent blood sugar management, regular health screenings, and maintaining a healthy lifestyle. Regular check-ups with your healthcare team are essential for early detection and intervention.

With proper management, people with diabetes can prevent or delay the onset of complications and lead healthy, active lives.
