Why High Blood Sugar Can Occur Despite a Normal HbA1c?
A normal HbA1c does not always mean your blood sugar is well controlled. Since HbA1c reflects an average over two to three months, it may not detect temporary spikes after meals or elevated fasting glucose caused by the dawn phenomenon or early insulin resistance. Conditions such as anemia can also affect HbA1c accuracy. Monitoring fasting, post-meal blood sugar, and, when needed, continuous glucose readings provides a more complete understanding of blood sugar control. Combining healthy lifestyle habits with regular monitoring can support better long-term metabolic health.
