Diabetes issues


Hello Doctor, last month I went to the hospital due to blurred vision and was diagnosed with diabetes (blood sugar over 300).
The doctor prescribed Metformin HCl 500 mg, to take half a tablet before breakfast and dinner, and to monitor my blood sugar two hours after each meal, ensuring it does not exceed 180.
I would like to ask:
1.
Every morning on an empty stomach, I drink a cup of okra water.
For breakfast, I usually have unsweetened soy milk with a pack of Quaker oatmeal or a vegetable egg pancake or a vegetable hand roll (with lettuce, mung bean sprouts, apple, cucumber, carrot, dried grapes, nuts, and wasabi sauce).
My blood sugar two hours after meals is between 150 and 170, but does not exceed 180.
Does this mean my blood sugar is under control? Why is my blood sugar still high even though I am not eating much?
2.
For dinner, I eat a quarter bowl of brown rice, two bowls of stir-fried vegetables (usually water-blanched, with at least two types such as amaranth, sweet potato leaves, cucumber, bitter melon, and bamboo shoots), loofah with clams, a portion of meat, and some fruit (either an apple, cherries, or kiwi).
After dinner, my blood sugar sometimes drops to just over 110.
Previously, I would drink a bottle of low-fat milk before bed to avoid low blood sugar (as I don’t feel hungry).
Is it necessary to drink milk if my blood sugar is over 110? Will my blood sugar drop further while I sleep?
3.
Despite consuming a lot of dietary fiber and drinking plenty of water (about 3000 cc of water and tea combined), I still experience constipation.
To help with bowel regularity, I take a pack of "San X Li" bifidobacterium and oligosaccharides in the morning and evening.
While this helps, I still do not have smooth bowel movements.
Am I consuming too much of this supplement? Thank you for your response.

Hello: 1.
Your blood sugar shows "improvement"; however, to determine if it has reached the control target, we still need to refer to your hemoglobin A1c levels.
2.
A postprandial blood sugar of 110 is not considered high.
It is possible for blood sugar levels to decrease when you are fasting during sleep.
Please check your fasting blood sugar level the next day and discuss any adjustments to your medication and diet with your physician.
3.
Constipation is not solely a dietary issue; establishing a regular bowel movement schedule is also important.
Additionally, avoid reading newspapers or using electronic devices while in the restroom.
Sometimes, abdominal massage (in a clockwise direction around the navel) can help.
If the issue persists, it is advisable to consult a gastroenterologist.

Managing diabetes effectively requires a comprehensive approach that includes dietary modifications, regular physical activity, and consistent monitoring of blood sugar levels. Based on your current practices and questions, let's delve into your situation and provide some insights.

1. Blood Sugar Control: You mentioned that your post-meal blood sugar levels range from 150 to 170 mg/dL, which is commendable as you are keeping them below the 180 mg/dL threshold set by your doctor. This indicates that you are managing your blood sugar relatively well, especially considering your initial diagnosis of diabetes with a blood sugar level over 300 mg/dL. However, it is essential to understand that blood sugar levels can be influenced by various factors, including the type and amount of food consumed, physical activity, stress levels, and even hormonal changes.
The reason your blood sugar might still be high despite eating what seems to be a healthy diet could be due to the carbohydrate content in the foods you are consuming. Even healthy foods can contribute to blood sugar spikes if consumed in large quantities or if they are high in carbohydrates. For instance, oats and certain fruits, while nutritious, contain carbohydrates that can raise blood sugar levels. It might be beneficial to monitor the carbohydrate content of your meals more closely and consider portion sizes.

2. Evening Routine and Blood Sugar Levels: You mentioned consuming a quarter bowl of brown rice, two bowls of stir-fried vegetables, and a fruit serving for dinner, followed by a 40-minute walk. If your blood sugar is around 110 mg/dL after dinner, that is a good sign, indicating that your body is processing the food well. Regarding your concern about drinking low-fat milk before bed, if your blood sugar is stable at 110 mg/dL, you may not need to consume additional calories from milk unless you feel hungry. It’s important to listen to your body; if you feel satisfied and your blood sugar is stable, you can skip the milk. However, if you experience symptoms of low blood sugar (like dizziness or shakiness), it might be wise to have a small snack.

3. Digestive Health and Fiber Intake: You are consuming a high-fiber diet and drinking plenty of water, which are both excellent for digestive health. However, if you are still experiencing constipation, it could be due to several factors. Sometimes, increasing fiber intake too quickly can lead to digestive discomfort. It’s also essential to ensure that you are getting a balance of soluble and insoluble fiber. Foods like fruits, vegetables, and whole grains provide soluble fiber, which can help with digestion, while whole grains and nuts provide insoluble fiber, which adds bulk to stool.

The use of probiotics, like the "三X利" you mentioned, can also support gut health, but it’s crucial to find the right balance. If you feel that you are taking too many supplements or if they are causing discomfort, it might be worth consulting with a healthcare provider or a dietitian. They can help you determine the appropriate dosage and whether any adjustments are necessary.

In summary, you are on the right track with your dietary choices and lifestyle changes. Continue to monitor your blood sugar levels, adjust your carbohydrate intake as needed, and maintain your physical activity. If digestive issues persist, consider consulting a healthcare professional for personalized advice. Regular follow-ups with your healthcare provider will also help you stay on top of your diabetes management and make necessary adjustments to your treatment plan.
