Blood Sugar Levels: Is 99 mg/dL a Cause for Concern? - Internal Medicine

When it comes to understanding blood sugar levels, a fasting blood glucose level of 99 mg/dL is indeed a point of interest, especially when compared to your previous readings of around 87 mg/dL. According to the American Diabetes Association, a fasting blood glucose level of 100 to 125 mg/dL is classified as "impaired fasting glucose," which is a prediabetic condition. A level of 99 mg/dL falls within the normal range (65-110 mg/dL), but it is on the higher end of that spectrum.
The concern here is not just the number itself but the trend it represents. If your blood sugar levels have been consistently rising, it may indicate that your body is beginning to struggle with insulin sensitivity or glucose metabolism. This could potentially lead to type 2 diabetes if lifestyle changes are not made.
Several factors can contribute to elevated blood sugar levels, including diet, physical activity, stress, and even sleep patterns. You mentioned a concern about "暴飲暴食" (binge eating), which can certainly impact blood sugar levels. Consuming large amounts of carbohydrates or sugary foods can lead to spikes in blood glucose, and if this behavior is frequent, it can contribute to insulin resistance over time.

To help manage and potentially lower your blood sugar levels, consider the following strategies:
1. Dietary Changes: Focus on a balanced diet rich in whole foods, including vegetables, fruits, whole grains, lean proteins, and healthy fats. Limit processed foods, sugary snacks, and beverages high in sugar. Monitoring carbohydrate intake can also be beneficial, as carbohydrates have the most significant impact on blood sugar levels.

2. Regular Exercise: Engaging in regular physical activity can improve insulin sensitivity and help your body use glucose more effectively. Aim for at least 150 minutes of moderate aerobic activity each week, such as brisk walking, cycling, or swimming.

3. Weight Management: If you are overweight, losing even a small percentage of your body weight can significantly improve insulin sensitivity and lower blood sugar levels.

4. Monitor Stress Levels: Chronic stress can lead to elevated cortisol levels, which may increase blood sugar levels. Incorporating stress-reducing techniques such as mindfulness, meditation, or yoga can be beneficial.

5. Regular Monitoring: Keep track of your blood sugar levels regularly. This will help you understand how your body responds to different foods and activities, allowing you to make informed decisions.

6. Consult a Healthcare Professional: Since you have noticed a change in your blood sugar levels, it would be wise to discuss this with your healthcare provider. They can provide personalized advice, conduct further testing if necessary, and help you develop a plan to manage your blood sugar effectively.

In summary, while a fasting blood glucose level of 99 mg/dL is not immediately alarming, it does warrant attention, especially if it represents a trend. By adopting healthier lifestyle habits and monitoring your blood sugar levels, you can take proactive steps to maintain your health and reduce the risk of developing diabetes in the future.
