Be in the know about your HbA1c

Your HbA1c and diabetes complications

A high HbA1c level means the amount of sugar in your blood has increased over the past few months and this can mean your blood vessels become damaged. Over time, this puts you at risk of life-changing complications, which could mean losing your sight or needing an amputation.

Even a slightly raised HbA1c still means you’re at risk of these complications. But there are things you can do to bring it down, and this will reduce your risk. But what should you be aiming for?

What’s a ‘normal’ HbA1c number?

First of all, there is no normal HbA1c for people with diabetes. Everyone’s different, so your healthcare team will give you an individual target which takes into account lots of things that are personal to you.

But there is an ideal number, 48 mmol/mol. We know this because studies show that when people have an HbA1c lower than 48, it drastically reduces their risk of complications.

We’re not saying 48 is easy to get to – we know diabetes is more complicated than that. But now you know a bit more about why your numbers matter, see here for formation you need to help bring your HbA1c closer to 48.
