What are symptoms of high HbA1c?

Since your HbA1c is the measure of your average blood sugar over a span of 2 to 3 months, a high HbA1c level means that your blood sugar has been consistently high. Because of this, you may start having symptoms of high blood sugar, such as:

  • Blurry vision
  • Feeling very tired
  • Frequent urination
  • Leg cramps
  • Being more hungry or thirsty than usual
  • Weight loss
