Diabetes in pregnancy

Gestational diabetes is high blood sugar (glucose) that develops during pregnancy and usually disappears after giving birth.

It can happen at any stage of pregnancy, but is more common in the second or third trimester.

It happens when your body cannot produce enough insulin – a hormone that helps control blood sugar levels – to meet your extra needs in pregnancy.

Gestational diabetes can cause problems for you and your baby during pregnancy and after birth. But the risks can be reduced if the condition is detected early and well managed.
