Targeting HbA1c

If Sydney endocrinologist Professor Stephen Twigg were diagnosed with type 2 diabetes tomorrow, his glycated haemoglobin (HbA1c) target would be as close to normal as possible. That is, ≤6%.

He says this target is appropriate considering he is in his mid-40s and does not have a history of cardiac disease. 

“As per current national guidelines, blood glucose targets should ideally be individualised.

“If I had to use more than just diet, exercise and metformin to get my HbA1c down, then I might then back the target off a little, but I don’t believe setting an HbA1c level at 7% for everyone with type 2 diabetes is optimal,” he says.

“The first 5–10 years after diagnosis are critically important. Once you are 10–20 years down the track, multiple medical problems typically emerge and the risks of tight glycaemic control become significantly more substantial.”
