Glycosylated hemoglobin 7.2% generally requires treatment and is an indicator of the level of long-term glycemic control in diabetic patients. Its level correlates with the average blood glucose concentration in the body over the last three months, and diabetic patients are generally required to keep their glycated hemoglobin within 7%, and it is recommended that patients with a glycated hemoglobin of 7.2% seek medical attention in a timely manner. Glycated hemoglobin is generally defined as the product of the combination of hemoglobin in the blood and sugars in the serum, and when the test is performed, the normal range may vary between 4% and 6%. In China, glycated hemoglobin is recommended as an additional diagnostic criterion for diabetes mellitus in medical institutions that use standardized testing methods and have strict quality control, with the condition of diagnosis being that the glycated hemoglobin is greater than or equal to 6.5%. Diabetes mellitus is usually caused by genetic factors, age factors, improper diet and other factors. It usually shows symptoms such as excessive drinking, excessive urination, excessive eating, and weight loss, and can be treated by using hypoglycemic drugs or insulin injections under the guidance of a doctor. If diabetes occurs, you should pay attention to rest, avoid overwork, regularly test your blood sugar, try to avoid eating foods with too much sugar, and if you feel unwell, go to the hospital in time to see a doctor, so as not to be negligent and delay your condition.
