Will eating honey pears the day before a blood sugar test affect the results?


I am currently 163 cm tall and weigh 63 kg, which I consider to be overweight.
In the one to two weeks leading up to my company's health check, I usually eat two honey pears (a type of Asian pear) around 10 PM.
The results of my check-up showed a reading of 120, while the normal range seems to be 70-110.
Is a difference of 10 significant? I'm wondering if my weight might be contributing to this, and I'm not sure how to improve my situation.

1.
Fasting for 8 hours meets the standard.
2.
You have abnormal fasting blood glucose, but it has not yet reached the diabetes threshold (fasting blood glucose greater than 126 mg/dL).
However, your risk of developing diabetes in the future is higher than that of the general population.
Both abnormal fasting blood glucose and diabetes are significantly associated with obesity.
The most effective way to reduce your risk of developing diabetes in the future is to lose weight.

Eating pears or any other food before a blood sugar test can indeed affect the results, particularly if the test is meant to measure fasting blood glucose levels. In your case, consuming two pears in the days leading up to your health check could potentially influence your blood sugar levels, especially if they were eaten close to the time of the test.
Pears are a healthy fruit, rich in dietary fiber and vitamins, but they also contain natural sugars. When you consume foods high in carbohydrates, including fruits, your body breaks them down into glucose, which then enters your bloodstream. This can lead to an increase in blood sugar levels, particularly if consumed shortly before a test.
In your situation, with a reported blood sugar level of 120 mg/dL, which is above the normal fasting range of 70-110 mg/dL, it is important to consider several factors. First, the timing of your pear consumption relative to the test is crucial. If you ate the pears on the same day as the test or the night before, it could have contributed to the elevated reading. However, if you consumed them a few days prior, their impact might be less significant, as blood sugar levels can fluctuate based on various factors, including stress, physical activity, and overall diet.

Additionally, being overweight can contribute to insulin resistance, which may lead to higher blood sugar levels. Insulin resistance occurs when the body's cells do not respond effectively to insulin, a hormone that helps regulate blood sugar levels. This condition is often associated with prediabetes and type 2 diabetes. Therefore, your weight could be a contributing factor to your blood sugar levels.

To improve your blood sugar levels and overall health, consider the following strategies:
1. Balanced Diet: Focus on a diet rich in whole foods, including vegetables, lean proteins, whole grains, and healthy fats. Limit your intake of refined sugars and processed foods, which can cause spikes in blood sugar.

2. Regular Exercise: Incorporating physical activity into your routine can help improve insulin sensitivity and lower blood sugar levels. Aim for at least 150 minutes of moderate-intensity exercise each week, such as brisk walking, cycling, or swimming.

3. Monitor Portion Sizes: Be mindful of portion sizes, especially when consuming carbohydrate-rich foods. This can help manage blood sugar levels more effectively.

4. Stay Hydrated: Drinking plenty of water can help your body maintain proper hydration and may support better blood sugar control.

5. Regular Check-ups: Keep track of your blood sugar levels and have regular check-ups with your healthcare provider. They can provide personalized advice and monitor your progress.

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

In conclusion, while eating pears before a blood sugar test can affect the results, it is essential to consider the timing and overall dietary habits leading up to the test. If you are concerned about your blood sugar levels or weight, it may be beneficial to consult with a healthcare professional or a registered dietitian for personalized guidance and support.
