What Do Glucose Test Results Mean?
Blood glucose test results indicate the sugar levels in the body. A normal fasting result is generally less than 100 mg/dL. Results between 100 and 125 mg/dL indicate prediabetes, while 126 mg/dL or higher may suggest diabetes.
The Importance of Early Diagnosis
Detecting diabetes early is crucial to prevent complications. An early diagnosis allows for lifestyle changes and appropriate treatments, which can significantly improve quality of life.
Interpreting Altered Results
If your glucose results are altered, it is important to stay calm. Consult your endocrinologist, such as Dr. Teresita Cortes, for a comprehensive evaluation and a personalized management plan.
Common Tests to Diagnose Diabetes
The most common tests include fasting glucose, the glucose tolerance test, and hemoglobin A1c. Each provides valuable information about your glucose control over time.

How to Act on Elevated Results
If your results are elevated, consider making changes to your diet, increasing physical activity, and following your doctor's recommendations. It is important not to self-medicate or adjust doses on your own.
Follow-Up Plan
Maintaining regular follow-up with your endocrinologist is essential. This includes periodic glucose checks and management adjustments as needed to ensure optimal control.
When to seek medical care
If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.
