The term ‘HbA1c’ refers to Glycated Haemoglobin. By measuring HbA1c, clinicians are able to find out our average blood sugar levels for the past three months. For people with diabetes, this is important, as the higher is HbA1c, greater is the risk of developing diabetes-related complications.

When your body processes sugar, the glucose in your bloodstream naturally attaches to haemoglobin, which then becomes glycated haemoglobin or HbA1c. The amount of glucose that combines with haemoglobin is directly proportional to the total amount of sugar in your system. So, higher the level of blood sugar, more is the level of HbA1c in your body.

Since red blood cells in the human body survive for 8-12 weeks before renewal, measuring HbA1c is used to reflect the average blood glucose levels over that duration. This provides a long-term gauge of blood glucose control.

Here are the various HbA1c levels with their indications:

HbA1c mmol/mol %
Normal Below 42 Below 6.0
Prediabetes 42 to 47 6.0 to 6.4
Diabetes 48 or above 6.5 or over


Two large-scale studies – the UK Prospective Diabetes Study (UKPDS) and the Diabetes Control and Complications Trial (DCCT) – demonstrated that improving HbA1c by 1% (or 11 mmol/mol) for people with type 1 diabetes or type 2 diabetes reduces the risk of micro-vascular complications by 25%.

HbA1c can be effectively lowered through a combination of lifestyle changes and medication. You can find the right anti-diabetic drugs at much lower prices in a generic medicine pharmacy.
