Introduction
Blood glucose of 6.7 mmol/L, if measured as fasting blood glucose, indicates impaired fasting glucose, suggesting reduced glucose regulation capacity and placing the individual in a pre-diabetic state. If measured as 2-hour postprandial blood glucose, 6.7 mmol/L falls within the normal range. It is important to adjust dietary habits, maintain regular physical activity, avoid unhealthy lifestyle practices, monitor blood glucose changes regularly, and manage emotions and stress.
Generally speaking, a blood glucose level of 6.7 mmol/L is considered to be impaired fasting glucose if measured as fasting blood glucose, which indicates reduced glucose regulation and suggests prediabetes. However, if it is measured as a 2-hour postprandial glucose level, 6.7 mmol/L falls within the normal range. Attention should be given to adjusting dietary patterns, engaging in regular physical activity, avoiding unhealthy lifestyle habits, monitoring blood glucose regularly, and managing emotions and stress. Detailed recommendations are as follows:
1. Adjust Diet
Reduce intake of refined sugars and refined carbohydrates, and increase consumption of whole grains, legumes, vegetables, and other foods rich in dietary fiber to delay glucose absorption. Daily staple food intake should be limited to 250-400 grams. Choose lean meats and seafood such as fish and shrimp, and avoid high-fat foods like fried foods and fatty meats.
2. Regular Exercise
Engage in at least 150 minutes per week of moderate-intensity aerobic exercise, such as brisk walking, swimming, or cycling, combined with resistance training twice a week, such as using dumbbells or resistance bands, to improve insulin sensitivity. If overweight or obese, aim to lose 5%-10% of body weight within 3-6 months.
3. Avoid Unhealthy Lifestyle Habits
Quit smoking and limit alcohol consumption, as smoking damages blood vessels and reduces insulin sensitivity, while excessive alcohol intake may cause blood glucose fluctuations. Ensure 7-8 hours of sleep daily, as staying up late can disrupt hormonal balance and worsen glucose metabolism.
4. Regular Blood Glucose Monitoring
Check fasting and 2-hour postprandial blood glucose levels every three months, and measure hemoglobin A1c annually to monitor trends in blood glucose. If fasting blood glucose is repeatedly ≥7.0 mmol/L or 2-hour postprandial glucose is ≥11.1 mmol/L, seek medical advice promptly for diagnosis.
5. Manage Emotions and Stress
Long-term anxiety and excessive stress stimulate the release of glucose-raising hormones, leading to elevated blood glucose levels. Alleviate stress through meditation, deep breathing, hobbies, and other methods to maintain emotional stability, which helps maintain stable blood glucose levels.
Any blood glucose level outside the normal range should be taken seriously, and appropriate preventive and management measures should be taken. If in doubt, consult a healthcare professional promptly.
