How to improve fasting blood glucose levels after gestational diabetes?


Hello Doctor: During my pregnancy, I strictly controlled my diet due to gestational diabetes, and my blood sugar levels remained within the normal range.
After giving birth, I continued to manage my diet, but due to a busy lifestyle, I have not been exercising much, only walking during my commute.
My fasting blood sugar levels every morning are between 95-98, with a maximum of 100 on one occasion.
Two hours after meals, my blood sugar ranges from 110-130 (varying based on my food intake).
Since my diet is already quite restricted and I am practicing intermittent fasting (eating dinner by 6 PM and not eating again until 10 AM the next day), I would like to ask the doctor if there are any other methods to lower my fasting blood sugar? Additionally, I would like to know if fasting blood sugar levels in the nineties, approaching one hundred, are highly likely to progress to prediabetes? Thank you for taking the time to provide this consultation!

Dr. Lin Jianliang reply Internal Medicine


Hello Ms.
Lin: It is recommended to continue dietary control and find time to exercise more to manage blood sugar levels.
The likelihood of developing high blood sugar in the future due to gestational diabetes is slightly higher than average.
Therefore, it is advised to maintain dietary control, engage in physical activity, and have regular follow-ups.

Improving fasting blood sugar levels after experiencing gestational diabetes is a crucial concern for many women. It’s commendable that you have maintained a strict diet during pregnancy and are continuing to monitor your blood sugar levels postpartum. Your current fasting blood sugar levels, ranging from 95 to 100 mg/dL, are indeed a point of concern, as they hover around the threshold that can indicate prediabetes.


Understanding Your Blood Sugar Levels
1. Fasting Blood Sugar: A fasting blood sugar level of 100 mg/dL or higher is considered to be in the prediabetes range. According to the American Diabetes Association, a fasting blood sugar level of 100-125 mg/dL is classified as "impaired fasting glucose." This means that while you are not yet diagnosed with diabetes, you are at an increased risk of developing it if lifestyle changes are not made.

2. Postprandial Blood Sugar: Your post-meal blood sugar levels of 110-130 mg/dL are within the normal range, especially if they are measured two hours after eating. The normal range for postprandial blood sugar is generally below 140 mg/dL. However, consistent monitoring is essential, as spikes can indicate how well your body is managing glucose.


Strategies to Improve Fasting Blood Sugar
1. Regular Physical Activity: While you mentioned that your lifestyle is busy and you are primarily walking during your commute, incorporating more structured exercise can significantly help in managing blood sugar levels. Aim for at least 150 minutes of moderate aerobic activity per week, such as brisk walking, swimming, or cycling. Resistance training is also beneficial, as it helps build muscle mass, which can improve insulin sensitivity.

2. Dietary Adjustments: You are already practicing intermittent fasting (16:8), which can be effective for some individuals. However, consider focusing on the quality of your meals:
- Low Glycemic Index (GI) Foods: Continue to prioritize low-GI foods, which are digested slowly and help maintain stable blood sugar levels. Foods such as whole grains, legumes, nuts, seeds, fruits, and non-starchy vegetables are excellent choices.

- Balanced Meals: Ensure that each meal contains a balance of carbohydrates, proteins, and healthy fats. This combination can help slow down the absorption of sugar into the bloodstream.

- Portion Control: Be mindful of portion sizes, especially for carbohydrate-rich foods, to prevent spikes in blood sugar.

3. Hydration: Staying well-hydrated is essential for overall health and can aid in blood sugar control. Aim to drink plenty of water throughout the day.

4. Sleep and Stress Management: Poor sleep and high stress can negatively impact blood sugar levels. Aim for 7-9 hours of quality sleep per night and consider stress-reducing practices such as mindfulness, yoga, or meditation.

5. Regular Monitoring: Continue to monitor your blood sugar levels regularly. Keeping a log of your readings can help you identify patterns and triggers that may affect your blood sugar.


Conclusion
Your current fasting blood sugar levels suggest that you are at risk for developing prediabetes, but with proactive management, you can potentially reverse this trend. Implementing a combination of regular exercise, dietary adjustments, and lifestyle changes can significantly improve your fasting blood sugar levels.
It’s also advisable to consult with a healthcare provider or a registered dietitian who specializes in diabetes management. They can provide personalized recommendations based on your specific situation and help you develop a comprehensive plan to maintain healthy blood sugar levels. Regular follow-ups will be essential to monitor your progress and make necessary adjustments to your management plan.
