does eating sugar before a1c test affect results

No, eating sugar before an A1C test does not significantly affect the results. The A1C test measures your average blood sugar levels over the past 2-3 months, not your current blood sugar level. Therefore, short-term changes in blood sugar, such as eating sugar before the test, will not impact the A1C result.

However, it's important to note that:

• Fasting is not required for an A1C test, unlike some other blood sugar tests.
• If your doctor orders additional tests (e.g., fasting glucose or cholesterol), you may need to fast for those.

Always follow your healthcare provider's instructions before any blood test.
