Symptoms of Prediabetes

Last December, I visited a urologist due to symptoms of frequent urination and erectile dysfunction.
At that time, my blood glucose level was 108 after fasting for 8 hours.
The doctor prescribed medication for benign prostatic hyperplasia, which improved my frequent urination symptoms.
However, recently, I have started experiencing frequent urination again.
Additionally, over the past month, despite eating as usual, I have lost two kilograms.
I have checked for other symptoms associated with prediabetes, such as acanthosis nigricans, slow-healing wounds in my lower extremities, and blurred vision, but I have not experienced any of these.
I would like to ask the doctor if it is possible that I may already have diabetes.

Hello: The typical initial symptoms of diabetes are increased thirst, increased urination, increased appetite, and weight loss (in later stages).
The acanthosis nigricans you mentioned is a possible but not common manifestation.
As for slow wound healing and blurred vision, these are complications caused by diabetes affecting the retina and peripheral blood vessels, respectively.
In fact, most people with diabetes do not exhibit symptoms, so the diagnosis of diabetes is often made through blood tests.
The most common tests are (1) fasting blood glucose and (2) hemoglobin A1c.
Based on your initial blood glucose level of 108, it suggests that you are not yet diabetic, but rather in the prediabetic stage.
However, since you are experiencing frequent urination and weight loss, it is still advisable for you to consult a family medicine or endocrinology specialist for a comprehensive diabetes evaluation for peace of mind.

More Info

Understanding the symptoms of prediabetes is crucial, especially for individuals who have already experienced elevated blood sugar levels, such as your previous reading of 108 mg/dL. Prediabetes is a condition where blood sugar levels are higher than normal but not yet high enough to be classified as diabetes. It is often a precursor to type 2 diabetes and can lead to serious health complications if not managed properly.

The symptoms of prediabetes can be subtle and may not always be noticeable. However, there are several key signs that you should not ignore:
1. Increased Thirst and Frequent Urination: As your body struggles to manage blood sugar levels, you may experience increased thirst (polydipsia) and frequent urination (polyuria). This is because excess glucose in the bloodstream can lead to increased urine production, causing dehydration.

2. Unexplained Weight Loss: While you mentioned that you have lost two kilograms recently without changing your eating habits, this can be a sign of diabetes. When the body cannot use glucose effectively for energy, it may start breaking down fat and muscle for fuel, leading to weight loss.

3. Fatigue: Feeling unusually tired or fatigued can be another symptom. When your body is not able to use glucose properly, it can lead to a lack of energy.

4. Blurred Vision: Changes in blood sugar levels can affect your vision. If you experience blurred vision, it could be a sign that your blood sugar levels are fluctuating.

5. Dark Patches of Skin: Acanthosis nigricans, characterized by dark, velvety patches of skin, often appears in areas such as the neck, armpits, and groin. This condition is associated with insulin resistance and can be an indicator of prediabetes.

6. Slow-Healing Wounds: If you notice that cuts or bruises are taking longer to heal than usual, it may be a sign of diabetes. High blood sugar levels can affect circulation and impair the body's ability to heal.

Given your history of elevated blood sugar and the symptoms you are experiencing, it is essential to consult with your healthcare provider. They may recommend further testing, such as an HbA1c test, which provides an average blood sugar level over the past two to three months, or a glucose tolerance test to assess how your body handles sugar.

It's also important to consider lifestyle factors that can influence blood sugar levels. Regular physical activity, a balanced diet rich in whole grains, fruits, vegetables, and lean proteins, and maintaining a healthy weight can significantly impact your blood sugar management. If you are experiencing symptoms like frequent urination and weight loss, it is advisable to seek medical attention promptly, as these could indicate that your blood sugar levels are becoming more problematic.

In summary, while you may not exhibit all the classic symptoms of diabetes, your previous elevated blood sugar level and current symptoms warrant further investigation. Early intervention can help prevent the progression to type 2 diabetes and improve your overall health. Please consult your healthcare provider for a thorough evaluation and personalized recommendations.
