To determine if you have type 2 diabetes, you should look for common symptoms and undergo specific tests. Here are the key steps:
Common Symptoms:
- Frequent urination
- Increased thirst
- Unexplained weight loss
- Fatigue
- Blurred vision
- Slow-healing sores
Diagnostic Tests:
-
A1C Test: Measures your average blood sugar level over the past 2-3 months.
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
-
Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast.
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary liquid.
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
If you experience symptoms or have risk factors (e.g., obesity, family history), consult a healthcare provider for testing and diagnosis.
