    Study Notes

    Blood Glucose Levels

    • Normal Fasting Blood Glucose: 4.0-5.5 mmol/L
    • Potentially Abnormal Fasting Blood Glucose: Below 4.0 mmol/L or above 5.5 mmol/L
    • Normal Random Blood Glucose: 4.0-7.8 mmol/L
    • Random Blood Glucose of 7.5 mmol/L is: Within the normal range for random blood glucose levels.
    • Fasting Blood Glucose Test: Specifically measures blood glucose levels after an overnight fast.

    Fasting Blood Glucose

    • Normal range: 4.0 - 5.5 mmol/L
    • Potentially abnormal level: Below 4.0 mmol/L or above 5.5 mmol/L

    Random Blood Glucose

    • Normal range: 4.0 - 7.0 mmol/L
    • 7.5 mmol/L exceeds the normal range and indicates potential hyperglycemia

    Specific Tests

    • Fasting blood glucose test specifically measures glucose levels after an overnight fast

    Implications of Low Blood Glucose

    • Fasting blood glucose below 4.0 mmol/L can lead to hypoglycemia, characterized by symptoms like dizziness, confusion, and fatigue

    Risks of High Blood Glucose

    • Random blood glucose exceeding 7.0 mmol/L can indicate hyperglycemia, potentially leading to long-term complications like cardiovascular disease, nerve damage, and kidney failure

    Blood Glucose Measurement Differences

    • Fasting blood glucose is measured after an overnight fast (8-12 hours), while random blood glucose can be measured at any time

    Influencing Factors

    • Fasting blood glucose levels can vary depending on factors like stress, medications, and recent meals

    Importance of Monitoring

    • Regular monitoring of blood glucose levels is crucial for individuals with known glucose regulation issues, such as diabetes, to manage blood sugar and prevent complications

    Fasting Blood Glucose

    • Normal range: 4.0 - 5.5 mmol/L
    • A fasting blood glucose level below 4.0 mmol/L could indicate hypoglycemia, leading to fatigue, dizziness, and potential loss of consciousness.
    • Consistently above 7.0 mmol/L indicates prediabetes or type 2 diabetes.
    • Potential health risks associated with a blood glucose level exceeding 7.0 mmol/L include increased risk of heart disease, stroke, nerve damage, and kidney disease.

    Random Blood Glucose

    • Normal range: 4.0 - 7.0 mmol/L
    • A random blood glucose level of 7.5 mmol/L is above the normal range, indicating potential hyperglycemia.

    Fasting vs. Random

    • Fasting blood glucose measures blood sugar after an overnight fast (8-12 hours)
    • Random blood glucose can be taken at any time of day, regardless of eating times.

    Factors Affecting Fasting Blood Glucose

    • Recent food intake
    • Stress
    • Exercise
    • Medications
    • Hormonal changes
    • Certain medical conditions (e.g. liver disease, kidney disease)

    Monitoring Blood Glucose

    • Regularly monitoring blood glucose levels is crucial for people with known glucose regulation issues (e.g. diabetes) to manage their condition and prevent complications.

    Clinical Applications

    • Random blood glucose measurements are useful for screening purposes and in emergency situations.
    • Fasting blood glucose tests are more specific for diagnosing diabetes and monitoring treatment effectiveness.

    Lifestyle Factors

    • Dietary choices (e.g. high sugar intake, refined carbohydrates)
    • Physical activity levels
    • Smoking
    • Stress
    • Sleep quality
