For a fasting blood sugar test, you should fast for at least 8 hours before the test. This means no food or drink (except water) during this period. Fasting ensures accurate results by measuring your baseline blood sugar levels.
- Timing: Overnight fasting is common, so you can schedule the test in the morning.
- Medications: Consult your doctor about whether to take your medications before the test.
- Other Tests: If your doctor is also checking cholesterol or other markers, fasting may be required for those tests as well.
Always follow your healthcare provider's specific instructions for the most accurate results.
