Can you have normal HbA1c levels but still experience high blood sugar?

Yes, it’s possible to have normal HbA1c levels and still experience occasional high blood sugar spikes, especially if you have impaired glucose tolerance or early-stage diabetes. HbA1c reflects an average of blood sugar over the past 2-3 months, so it may not capture short-term fluctuations. If you experience symptoms of high blood sugar or have risk factors like obesity or family history, additional tests such as continuous glucose monitoring (CGM) or an oral glucose tolerance test (OGTT) may be needed to assess your overall glucose control.
