Diabetes Consultation


Hello Doctor: On April 30th, my fasting blood sugar was 98, and my hemoglobin A1c was 4.8.
On May 15th, my fasting blood sugar was 91, and my hemoglobin A1c was 4.7.
However, on August 14th, my fasting blood sugar was 102, and on August 27th, it was 104, but I did not have my hemoglobin A1c tested during these two visits.
I have started to feel symptoms such as tingling in my feet, fatigue, blurred vision, and frequent urination.
Could this be diabetes? I am very anxious.
I'm sorry.

The diagnostic criteria for diabetes mellitus include a fasting blood glucose level of 126 mg/dL or higher, or a hemoglobin A1c level of 6.5% or higher.
Symptoms such as tingling, fatigue, blurred vision, and frequent urination cannot currently be interpreted as indicative of diabetes.

Hello,
It's understandable to feel concerned about your health, especially when experiencing symptoms that could be related to diabetes. Based on the blood sugar readings you've provided, your fasting blood glucose levels have been fluctuating, with the most recent readings of 102 and 104 mg/dL, which are slightly above the normal range (typically defined as less than 100 mg/dL for fasting blood sugar). However, these levels are not yet high enough to diagnose diabetes, as the diagnostic criteria for diabetes include fasting blood glucose levels of 126 mg/dL or higher, or an HbA1c (glycated hemoglobin) level of 6.5% or higher.

Your HbA1c levels of 4.8% and 4.7% are well within the normal range, indicating good blood sugar control over the past few months. However, the symptoms you mentioned—tingling in the feet, fatigue, blurred vision, and increased urination—are concerning and warrant further investigation. These symptoms can be indicative of diabetic neuropathy, which is a complication of diabetes, but they can also arise from other conditions.

Given your family history of diabetes, it is wise to remain vigilant about your health. The symptoms you are experiencing could be related to several factors, including stress, hormonal changes, or even anxiety, which can manifest physically. It’s important to consult with a healthcare professional who can evaluate your symptoms in the context of your overall health and family history.

Here are some steps you can take:
1. Seek Medical Advice: Schedule an appointment with your healthcare provider to discuss your symptoms and concerns. They may recommend further testing, including a comprehensive metabolic panel, additional blood glucose tests, or even a referral to an endocrinologist.

2. Monitor Your Symptoms: Keep a detailed record of your symptoms, including when they occur, their severity, and any potential triggers. This information can be helpful for your healthcare provider.

3. Lifestyle Modifications: Regardless of your current blood sugar levels, adopting a healthy lifestyle can be beneficial. This includes a balanced diet rich in whole grains, fruits, vegetables, lean proteins, and healthy fats, as well as regular physical activity. Maintaining a healthy weight can also help reduce the risk of developing diabetes.

4. Regular Monitoring: If you have concerns about your blood sugar levels, consider monitoring them more frequently, especially after meals. This can provide additional insight into how your body is responding to different foods and activities.

5. Stay Informed: Educate yourself about diabetes and its symptoms. Understanding the condition can empower you to make informed decisions about your health.

In summary, while your current blood sugar levels do not indicate diabetes, the symptoms you are experiencing should not be ignored. It is crucial to consult with a healthcare professional who can provide a thorough evaluation and guide you on the appropriate next steps. Remember, early detection and intervention can significantly improve outcomes in managing diabetes and its complications. Take care of yourself, and don’t hesitate to reach out for support.
