Diabetes issues

Hello, I had a fasting blood glucose level of 93 mg/dL during my health check in mid-2008, and it increased to 104 mg/dL during my health check in mid-2011.
Does fasting blood glucose fluctuate or does it consistently rise year after year? There are reports stating that a level of 104 mg/dL is considered prediabetes, and that diabetes may develop in 6 to 7 years.
Is this true?

Hello, A San Ge:
In your letter, you mentioned your fasting blood glucose levels.
According to the standards published by the Department of Health, a normal fasting blood glucose level is below 100 mg/dL.
A fasting blood glucose level between 100 and 126 mg/dL indicates abnormal fasting glucose, which signifies impaired glucose tolerance.
This range is a transitional zone between normal and diabetes, indicating increased insulin resistance, meaning your body is unable to adequately metabolize and utilize glucose.
Generally, blood glucose levels fluctuate daily based on meal timing and content.
As age, weight, or certain diseases increase, blood glucose levels can also become unstable.
Therefore, to prevent future progression to diabetes (defined as fasting blood glucose levels consistently above 126 mg/dL or random blood glucose levels greater than or equal to 200 mg/dL accompanied by diabetes symptoms), please pay attention to a low glycemic index diet, increase your intake of high-fiber foods, and engage in regular aerobic exercise to maintain your weight within an ideal range.
Additionally, I recommend that you have your fasting and postprandial blood glucose levels rechecked approximately every 3 to 6 months at a family medicine, general internal medicine, or endocrinology clinic as a reference for monitoring control.
Individuals with abnormal fasting blood glucose do not necessarily progress to diabetes; it largely depends on dietary habits, weight management, exercise, and genetic predisposition.
With commitment to control, preventing diabetes is indeed possible.

Understanding blood sugar fluctuations and the risks associated with prediabetes is crucial for maintaining overall health and preventing the progression to type 2 diabetes. Your concern about the gradual increase in fasting blood sugar levels from 93 mg/dL to 104 mg/dL over a span of several years is valid and reflects a common trend observed in many individuals.

Firstly, it is important to understand that blood sugar levels can indeed fluctuate due to various factors, including diet, physical activity, stress, and hormonal changes. A fasting blood sugar level of 100 mg/dL to 125 mg/dL is classified as prediabetes according to the American Diabetes Association (ADA). This means that while your blood sugar levels are not high enough to be diagnosed as diabetes, they are elevated and indicate an increased risk of developing type 2 diabetes in the future.

The progression from prediabetes to diabetes is not guaranteed, but studies have shown that individuals with prediabetes are at a higher risk of developing type 2 diabetes within 5 to 10 years if no lifestyle changes are made. The risk factors for this progression include obesity, sedentary lifestyle, family history of diabetes, and poor dietary habits. Therefore, maintaining a healthy weight, engaging in regular physical activity, and adopting a balanced diet can significantly reduce the risk of developing diabetes.

In your case, the increase in fasting blood sugar from 93 mg/dL to 104 mg/dL over a few years suggests a trend that should be monitored closely. It is essential to take proactive steps to manage your blood sugar levels. Here are some recommendations:
1. Regular Monitoring: Keep track of your blood sugar levels regularly. This can help you identify patterns and make necessary adjustments to your lifestyle.

2. Healthy Diet: Focus on a diet rich in whole foods, including fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit the intake of processed foods, sugary beverages, and high-glycemic index foods that can cause spikes in blood sugar levels.

3. Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise each week, along with strength training exercises at least twice a week. Regular physical activity helps improve insulin sensitivity and can aid in weight management.

4. Weight Management: If you are overweight, even a modest weight loss of 5-10% of your body weight can significantly reduce the risk of developing diabetes.

5. Stress Management: Chronic stress can affect blood sugar levels. Incorporate stress-reducing activities such as yoga, meditation, or deep-breathing exercises into your routine.

6. Regular Check-ups: Continue to have regular health check-ups, including blood tests to monitor your fasting blood sugar and HbA1c levels. This will help you and your healthcare provider assess your risk and make informed decisions about your health.

7. Consult a Healthcare Professional: If you have concerns about your blood sugar levels or risk of diabetes, consider consulting with a healthcare professional or a registered dietitian. They can provide personalized advice and support based on your individual health needs.

In conclusion, while your fasting blood sugar levels have shown a slight increase, it is not an inevitable path to diabetes. By adopting a healthy lifestyle and monitoring your blood sugar levels, you can significantly reduce your risk and maintain your health. Remember, early intervention is key in preventing the progression from prediabetes to diabetes.
