Blood Sugar Levels: Should You Worry About Your Readings? - Internal Medicine

Understanding blood sugar levels is crucial for maintaining overall health, especially as they can be indicative of underlying conditions such as prediabetes or diabetes. Based on the information you've provided, let's break down your blood sugar readings and address your concerns.

Your fasting blood sugar levels were 89 mg/dL on March 1 and increased to 98 mg/dL on March 20. Both of these readings fall within the normal range, as per the American Diabetes Association guidelines, which state that normal fasting blood glucose levels should be below 100 mg/dL. The increase, while it may seem concerning, is still within the acceptable range and does not indicate diabetes.

Your HbA1c level of 5.0% is also well within the normal range, indicating good blood sugar control over the past two to three months. An HbA1c below 5.7% is considered normal, and your level suggests that you are not at risk for diabetes at this time.

Regarding your fasting period before the blood test, a fasting period of 10 hours (from 8 PM to 10 AM) is generally acceptable for a fasting blood glucose test. It is important to ensure that you do not consume any food or caloric beverages during this time, which you seem to have adhered to.

You mentioned experiencing high levels of stress and anxiety, which can indeed affect blood sugar levels. Stress triggers the release of hormones such as cortisol and adrenaline, which can lead to increased blood sugar levels. This physiological response is part of the body's fight-or-flight mechanism, and it can temporarily elevate blood glucose levels even in individuals without diabetes. Therefore, your elevated reading of 98 mg/dL could be influenced by your stress levels, especially if you were feeling anxious before the test.

Given that you have been eating healthily and exercising regularly, these lifestyle choices are beneficial for maintaining stable blood sugar levels. Regular physical activity helps improve insulin sensitivity and can help lower blood sugar levels over time. Additionally, a balanced diet that is low in refined sugars and high in fiber can also contribute to better blood sugar control.

As for whether you should check your postprandial (after meal) blood sugar levels, it may be a good idea if you have concerns about how your body responds to food. Monitoring postprandial blood sugar can provide insights into how your body manages glucose after eating, especially if you are experiencing symptoms or have concerns about your health. However, if you are feeling well and your fasting and HbA1c levels are normal, it may not be necessary to check your postprandial levels at this time.

In summary, while your fasting blood sugar levels have shown a slight increase, they remain within the normal range, and your HbA1c indicates good long-term control. Stress and anxiety can influence blood sugar readings, so managing these factors through relaxation techniques, regular exercise, and a healthy diet is essential. If you continue to have concerns or if your readings change significantly, it would be wise to consult with your healthcare provider for further evaluation and guidance. Remember, maintaining a healthy lifestyle is key to preventing potential health issues in the future.
