Prediabetes
Hello, doctor.
My height is 173 cm and my weight is 42.2 kg.
In March, my weight was 45.2 kg.
Due to weight loss, I underwent blood glucose and thyroid tests.
The results showed fasting blood glucose of 96 mg/dL, hemoglobin A1c of 5.7%, eAG of 117 mg/dL, free T4 of 1.05 ng/dL, and TSH of 0.741 µIU/mL.
There is no family history of diabetes, and I am underweight with no hypertension, hyperlipidemia, or fatty liver.
Previously, I exercised little and often consumed carbohydrate-rich foods, rarely eating sweets.
Since February of this year, I have been exercising at least three times a week, including 30 minutes of walking and stretching, or 10 minutes of running, 15 minutes of walking, and 15 minutes of stretching.
I avoid fried foods, spicy foods, and soft drinks, and since May, I have reduced my gluten intake (no noodles or bread).
I have several questions for you, doctor:
1.
Could my elevated blood sugar be due to excessive carbohydrate intake or stress? Since December of last year, I have been experiencing anxiety and various physical discomforts.
I have consulted urology (for cystitis and hematuria), gastroenterology (for gastroesophageal reflux and constipation/diarrhea), and gynecology (for irregular menstrual periods).
Could stress be causing my blood sugar to rise?
2.
Is my weight loss due to high blood sugar? I have had poor gastrointestinal absorption since childhood, but I have never lost weight to this extent.
3.
My primary care physician indicated that I am in the prediabetic stage and that I do not need medication, only dietary control.
Is it true that I really do not need medication? I am concerned that once I start medication, I will have to take it for life.
4.
Should I be referred to a metabolic specialist, or is it sufficient to follow up with my primary care physician in six months?
5.
Most cases of prediabetes I see are in overweight individuals, and weight loss can reverse diabetes.
Given that I am underweight, should I lose more weight? I feel that I am frighteningly thin and want to gain weight, but I am worried about affecting my blood sugar.
6.
Can I exercise before meals, or is it necessary to exercise after eating? Currently, I drink a cup of oat milk before exercising in the morning, then eat a boiled egg or steamed vegetables after exercising, and take a 15-minute walk after each meal.
I have quite a few questions.
Thank you, doctor.

Hello: The normal range for fasting blood glucose levels is typically 70 to 100 mg/dL, and the normal range for hemoglobin A1c is 4 to 6%.
I'm not sure what your laboratory's standard range is.
For prediabetes, dietary changes and exercise can be effective in managing the condition, and medication is not always necessary.
Both family medicine and endocrinology can monitor your progress.
Exercising on an empty stomach may lead to symptoms of hypoglycemia; it's advisable to have a small snack, not too much, and rest for 15 minutes before resuming exercise.
After meals, it's recommended to rest for about an hour before engaging in moderate-intensity exercise.

More Info
Understanding prediabetes is crucial for managing your health effectively, especially given your recent lab results and lifestyle changes. Prediabetes is a condition where blood sugar levels are higher than normal but not yet high enough to be classified as diabetes. Your fasting blood sugar of 96 mg/dL and HbA1c of 5.7% indicate that you are indeed in the prediabetic range.
1. Causes of Elevated Blood Sugar
Your question about whether your carbohydrate intake, particularly from pasta, or stress could be contributing to your elevated blood sugar levels is valid. High carbohydrate consumption can lead to spikes in blood sugar, especially if those carbohydrates are refined or processed. However, your overall diet seems to have improved significantly since you have reduced your intake of fried foods, spicy foods, and sugary drinks.
Stress can also play a significant role in blood sugar regulation. When you experience stress, your body releases hormones like cortisol and adrenaline, which can increase blood sugar levels. Given that you've mentioned experiencing anxiety and various health issues, it is possible that stress could be impacting your blood sugar levels.
2. Weight Loss and Blood Sugar
Regarding your weight loss, it is important to note that unintentional weight loss can sometimes be a sign of underlying health issues, including diabetes. However, in your case, it seems more likely that your weight loss is related to your dietary changes and possibly stress. Since you have a history of poor nutrient absorption, it may also be contributing to your weight loss.
3. Medication and Management
Your healthcare provider's recommendation to manage your prediabetes through lifestyle changes rather than medication is common, especially for individuals who are not overweight. Many people with prediabetes can effectively reverse their condition through diet, exercise, and weight management. It’s understandable to be concerned about the long-term use of medication, and lifestyle changes can often be a more sustainable approach.
4. Referral to a Specialist
Whether or not you should see an endocrinologist or a metabolic specialist depends on your ongoing symptoms and how well you manage your prediabetes. If you continue to experience significant health issues or if your blood sugar levels do not improve with lifestyle changes, a referral may be beneficial. However, regular follow-ups with your primary care physician every six months can also be sufficient for monitoring your condition.
5. Weight Management
Your concern about being underweight and whether you need to lose more weight is important. In general, weight loss is recommended for those who are overweight or obese to help manage blood sugar levels. However, since you are already underweight, the focus should be on maintaining a healthy weight rather than losing more. It may be beneficial to consult with a nutritionist who can help you create a balanced meal plan that supports weight gain while managing your blood sugar levels.
6. Timing of Exercise
As for your question about exercising before or after meals, both can be beneficial. Exercising before meals can help lower blood sugar levels, while post-meal exercise can aid in glucose uptake by the muscles, helping to stabilize blood sugar levels. Your routine of drinking oat milk before exercising and then consuming a boiled egg or steamed vegetables afterward seems appropriate.
Conclusion
In summary, managing prediabetes involves a multifaceted approach that includes dietary modifications, regular physical activity, stress management, and regular monitoring of blood sugar levels. Your proactive steps towards improving your health are commendable, and it’s essential to continue these efforts. If you have ongoing concerns or if your symptoms persist, don’t hesitate to reach out to your healthcare provider for further evaluation and guidance.
