Health check-up shows elevated fasting blood glucose levels?


Hello Doctor, I had a health check-up in 2021 with a fasting blood glucose level of 100 mg/dL and low-density lipoprotein (LDL) cholesterol of 139 mg/dL.
On January 15, 2022, my fasting blood glucose was 112 mg/dL and total cholesterol was 220 mg/dL.
The next day, due to a company-mandated health examination, I had a second blood test with a fasting blood glucose of 106 mg/dL and total cholesterol of 240 mg/dL.
After seeing the report, I became very anxious about my cholesterol and blood sugar levels, so I consulted a metabolic specialist for further testing.

On February 5, 2022, my fasting blood glucose was 97 mg/dL, glycated hemoglobin (HbA1c) was 5.5%, and LDL cholesterol was 183 mg/dL.
On February 26, 2022, my fasting blood glucose was 104 mg/dL, LDL cholesterol was 167 mg/dL, and high-density lipoprotein (HDL) cholesterol was 47 mg/dL.

I would like to ask the doctor about controlling my blood sugar and cholesterol levels.
I am an office worker who exercises three times a week (jogging and weight training) for one hour each time.
I do not smoke and drink alcohol sparingly (about twice a month, with two cocktails each time).
I consume no-sugar beverages and only drink pure tea.
I have dessert about once a week and do not have a breakfast habit.
Currently, I eat very little white rice (about half a bowl, as advised by diabetes education units), and my main dishes consist of meat, fish, and simple stir-fried vegetables.

I have had panic disorder for many years and am very concerned about my health.
I am afraid of developing metabolic syndrome.
My father developed diabetes after years of alcohol abuse (he was diagnosed several years after I was born).
How should I adjust my diet, exercise frequency, and lifestyle habits to achieve normal values? Since January 2022, I have been working harder to exercise, but my recent fasting blood glucose level exceeded the normal range again, leaving me feeling very helpless.
Please provide me with some guidance.
Thank you.

Hello: It is recommended to avoid foods and beverages that contain alcohol.
Fruits and carbohydrate-rich foods, such as desserts, can also lead to issues with blood sugar and blood lipids.
It is advised to have a controlled diet for breakfast, and to exercise regularly and consistently to achieve good results.

More Info


Managing high fasting blood sugar and cholesterol levels is a common concern, especially for individuals with a family history of diabetes or metabolic disorders. Based on your health check results and lifestyle, it seems you are already taking significant steps to manage your health. However, let’s delve deeper into your situation and provide some guidance on how to optimize your blood sugar and cholesterol levels.


Understanding Your Blood Sugar and Cholesterol Levels
1. Fasting Blood Sugar Levels: Your fasting blood sugar readings have fluctuated between 97 mg/dL and 112 mg/dL. According to the American Diabetes Association, a fasting blood sugar level of 100-125 mg/dL is considered "prediabetes," while levels above 126 mg/dL indicate diabetes. Your readings suggest that you are on the borderline, which is a critical point for intervention.

2. Cholesterol Levels: Your total cholesterol levels have also shown variability, with readings ranging from 220 mg/dL to 240 mg/dL. A total cholesterol level below 200 mg/dL is considered desirable, while levels above 240 mg/dL are high. Your LDL (low-density lipoprotein) cholesterol levels have been fluctuating as well, which is concerning since high LDL is associated with an increased risk of heart disease.


Lifestyle Modifications
Given your current lifestyle and health metrics, here are some recommendations to help you manage your blood sugar and cholesterol levels effectively:
1. Dietary Adjustments:
- Balanced Meals: While you are already consuming less rice, ensure that your meals are balanced with adequate protein, healthy fats, and fiber. Incorporate more vegetables, whole grains, and legumes into your diet. Foods high in fiber, such as oats, beans, and leafy greens, can help regulate blood sugar levels.

- Healthy Fats: Focus on incorporating healthy fats from sources like avocados, nuts, seeds, and olive oil. These can help improve your cholesterol levels.

- Limit Processed Foods: Reduce your intake of processed foods, sugary snacks, and beverages, as these can spike blood sugar levels.

- Regular Meal Timing: Although you mentioned not having breakfast, consider incorporating a healthy breakfast to stabilize your blood sugar levels throughout the day. This could be something simple like oatmeal with nuts or a smoothie with spinach and protein.

2. Exercise Routine:
- Consistency is Key: You are already exercising three times a week, which is great. Aim for at least 150 minutes of moderate aerobic activity per week, combined with strength training exercises at least twice a week. This can help improve insulin sensitivity and lower blood sugar levels.

- Incorporate More Activity: If possible, try to incorporate more physical activity into your daily routine, such as walking during breaks or taking the stairs instead of the elevator.

3. Stress Management:
- Addressing Anxiety: Since you mentioned having panic disorder, managing stress is crucial. Consider practices such as mindfulness, yoga, or meditation, which can help reduce stress levels and improve overall well-being.

- Sleep Hygiene: Ensure you are getting adequate sleep, as poor sleep can negatively impact blood sugar and cholesterol levels.

4. Regular Monitoring:
- Keep Track of Your Levels: Regularly monitor your blood sugar and cholesterol levels to understand how your lifestyle changes are impacting your health. This will also help you identify any patterns or triggers that may cause spikes in your readings.

5. Consult Healthcare Professionals:
- Dietitian Consultation: Consider working with a registered dietitian who can help you create a personalized meal plan that aligns with your health goals.

- Regular Check-ups: Continue to have regular check-ups with your healthcare provider to monitor your progress and make necessary adjustments to your management plan.


Conclusion
Managing high fasting blood sugar and cholesterol levels requires a multifaceted approach that includes dietary changes, regular physical activity, stress management, and consistent monitoring. By making these adjustments and staying proactive about your health, you can work towards achieving normal blood sugar and cholesterol levels. Remember, it’s essential to be patient with yourself and recognize that lifestyle changes take time to show results. If you have any further questions or need additional support, don’t hesitate to reach out to your healthcare provider.
