Progress in the Study of Glycosylated Haemoglobin Variability Index in Relation to Chronic Complications of Diabetes Mellitus

Diabetes mellitus (DM) is a common endocrine disease that can cause damage to tissues and organs throughout the body. Glycosylated haemoglobin (HbA1c) is considered to be the gold standard for assessing glycaemic control and treatment outcomes in patients with diabetes, but there is individual variability that affects the accurate interpretation of blood glucose. The glycosylated haemoglobin variability index (HGI) is a measure of individual variability in HbA1c and can be used in the management and treatment of patients with DM. In this paper, the relationship between HGI and chronic complications of DM is reviewed and discussed, with the aim of providing a more individualized and accurate reference for clinical management of blood glucose and risk assessment of chronic complications in DM patients, reducing and delaying the occurrence of chronic complications of diabetes and improving the quality of life of DM patients.
