What causes HbA1c to rise?

HbA1c levels can rise due to various factors. The primary factor is consistently high blood sugar levels over time, as glucose in the bloodstream binds to hemoglobin. Factors such as poor blood sugar control, inadequate diabetes management, high carbohydrate intake, lack of physical activity, stress, illness, certain medications, and conditions affecting red blood cells can contribute to elevated HbA1c levels. It is essential to work with a healthcare professional to identify the underlying causes and develop a personalized diabetes management plan to maintain optimal blood sugar control.
