Overview - Gestational diabetes
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.

Gestational diabetes can cause problems for you and your baby during pregnancy and after birth.
