Question
Dear Experts: What is glycated hemoglobin? What are the relationships with diabetes?
Answer
Glycated hemoglobin refers to the part of hemoglobin that has combined with glucose in the blood. When the blood glucose concentration is high, the amount of glycated hemoglobin formed in the body will also be relatively high. The lifespan of red blood cells in the human body is generally 120 days. Before these cells die, the content of glycated hemoglobin in the blood remains relatively stable, unaffected by daily fluctuations in glucose levels, exercise, or food intake. It reflects the average blood sugar concentration over the past 6-8 weeks and is unrelated to factors such as the time of blood draw, whether the patient is fasting, or whether insulin is being used. Therefore, it is an excellent indicator for determining the blood sugar control effect of diabetic patients over a certain period of time. Are you satisfied with my answer?
