Glycated hemoglobin 11.2% is generally more serious. The normal value of glycated hemoglobin is between 4% and 6%, 11.2% is already higher than the normal value, and indicates that the blood sugar in the body is elevated, which may cause diabetes if it is not controlled in time, and may cause other complications in serious cases, so it is more serious. In China, it is recommended to use glycosylated hemoglobin as the supplementary diagnostic standard for diabetes in medical institutions with standardized testing methods and strict quality control, and the condition for diagnosis is that the glycosylated hemoglobin is greater than or equal to 6.5%. Glycated hemoglobin of 11.2% may be caused by improper diet, reduced pancreatic function, etc., which will lead to a gradual increase in blood glucose levels, and also cause polyuria, excessive drinking, weight loss, increased urination, and thirst, which may affect normal life in severe cases. When the glycated hemoglobin is higher than normal, it is important to pay attention to it and seek medical treatment in time.
