Am I Diabetic? Blood Sugar and Cholesterol Levels - Internal Medicine

Share to:

Could you please tell me if I have diabetes?


Hello, last year my tests were normal, but this year I received my health check results showing abnormal blood sugar and lipid levels.
Am I diabetic? After fasting for over 12 hours, my weight is 49 kg and my height is 155.7 cm.
My cholesterol (CHOL) is 212 (normal range 0-200), my fasting blood sugar (AC) is 102 (normal range 70-100), my creatinine is 0.54 (normal range 0.44-1), and my high-density lipoprotein (HDL) is 51.00 (normal range 60-200).
All other functions are normal, my weight has not changed, and I do not drink excessive amounts of water.
I urinate about 2-3 times a day, but if I drink a lot of water, I will urinate more frequently.

Dear Ms.
Vivi:
1.
Your fasting blood glucose level is 102 mg/dL, your body mass index (BMI) is 20.4 kg/m², and you do not exhibit any obvious symptoms of diabetes.

2.
According to the diagnostic criteria for diabetes set by the American Diabetes Association:
a.
A fasting plasma glucose level of ≥126 mg/dL after fasting for at least 8 hours,
b.
A 2-hour plasma glucose level of ≥200 mg/dL during an oral glucose tolerance test,
c.
An HbA1c of ≥6.5% (this must be confirmed with a method that is certified by the National Glycohemoglobin Standardization Program [NGSP] and meets the Diabetes Control and Complications Trial [DCCT] standards).

The above criteria (a, b, c) must be met on two separate occasions.

d.
If there are clinical symptoms of diabetes (such as polydipsia, polyuria, polyphagia, and unexplained weight loss), any plasma glucose level of ≥200 mg/dL is sufficient for diagnosis (this situation only requires one occurrence).

Based on this information, it is unlikely that you have type 2 diabetes; it can only be classified as "impaired fasting glucose."
3.
Many physicians recommend conducting a glucose tolerance test for patients with elevated fasting blood glucose levels.
Therefore, if you have further questions, it is advisable to consult your family physician or an endocrinologist for additional evaluation.

More Info


Based on the information you've provided, your fasting blood sugar level is 102 mg/dL, which is considered to be in the range of "impaired fasting glucose" or "prediabetes." According to the American Diabetes Association (ADA), a fasting blood sugar level of 100 to 125 mg/dL indicates prediabetes, while a level of 126 mg/dL or higher on two separate tests is diagnostic for diabetes. Therefore, while you are not currently diagnosed with diabetes, you are at an increased risk and should monitor your blood sugar levels closely.

Your total cholesterol level is 212 mg/dL, which is slightly above the recommended level of less than 200 mg/dL. This could indicate a potential risk for cardiovascular issues, especially if your LDL (low-density lipoprotein) cholesterol is also elevated. However, you did not provide your LDL levels, which are crucial for assessing your overall cholesterol profile. High levels of LDL cholesterol can contribute to the buildup of plaque in your arteries, increasing the risk of heart disease.

Your high-density lipoprotein (HDL) cholesterol level is 51 mg/dL, which is within the normal range but slightly below the optimal level of 60 mg/dL or higher. HDL is often referred to as "good" cholesterol because it helps remove other forms of cholesterol from your bloodstream. A higher level of HDL is generally associated with a lower risk of heart disease.

It's also important to note that you mentioned no significant changes in your weight, no excessive thirst, and urination patterns that seem normal for you. These are positive signs, as classic symptoms of diabetes include increased thirst, frequent urination, and unexplained weight loss. However, the fact that you have a fasting blood sugar level in the prediabetes range means you should take proactive steps to manage your health.

Here are some recommendations for you:
1. Dietary Changes: Focus on a balanced diet rich in whole grains, fruits, vegetables, lean proteins, and healthy fats. Limit your intake of refined sugars and carbohydrates, as these can spike blood sugar levels.

2. Physical Activity: Regular exercise can help improve insulin sensitivity and lower blood sugar levels. Aim for at least 150 minutes of moderate aerobic activity each week, such as brisk walking, swimming, or cycling.

3. Regular Monitoring: Keep track of your blood sugar levels, especially if you notice any symptoms or changes in your health. It may be beneficial to check your blood sugar levels periodically, especially after meals.

4. Consult a Healthcare Provider: Given your cholesterol levels and fasting blood sugar, it would be wise to consult with a healthcare provider or a registered dietitian. They can help you create a personalized plan to manage your risk factors effectively.

5. Follow-Up Testing: Consider having your blood sugar and cholesterol levels rechecked in a few months to monitor any changes. If your fasting blood sugar remains elevated or if you develop symptoms of diabetes, further testing may be warranted.

In summary, while you are not currently diagnosed with diabetes, your fasting blood sugar level indicates that you are at risk. By making lifestyle changes and monitoring your health, you can significantly reduce your risk of developing diabetes and improve your overall well-being.
