Gestational diabetes

Gestational diabetes is a type of diabetes that can develop during pregnancy. It is also known as ‘hyperglycaemia in pregnancy’.

If you are diagnosed with gestational diabetes, or you have been told you are at risk, it is natural to feel concerned. But gestational diabetes is fairly common: it affects around one in 20 pregnancies.

In the UK, all pregnant women who are considered at risk are offered a test for gestational diabetes during pregnancy. This is because identifying and treating the condition reduces the risks to you and your baby. Women are sometimes surprised to find out they have the condition as it’s often picked up before it shows any obvious symptoms.

There are several medical treatments that can help with gestational diabetes. However, some women are able to manage it through diet and other lifestyle factors. This means that, with the support of your specialist team, you have an important role in keeping you and your baby healthy through your pregnancy.
