Know your HbA1c

Diabetes can lead to serious complications, and the higher your HbA1c, the more you're at risk of developing them. We know it's not easy to bring your levels down, but the closer you get to your target, the more you'll reduce this risk.

Find out more about HbA1c

If your HbA1c is a 'little over' 48 for a period of time, it is a big deal.

Even a slightly high HbA1c means you're more at risk of developing serious complications, like sight loss and amputation. Knowing your levels and understanding what they mean can help you reduce this risk.

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, we'll show you the information you need to help bring your HbA1c closer to 48.
