Gestational diabetes is a metabolic change during pregnancy. It is treatable, and with the right support you have a strong foundation for your baby's healthy development.
During pregnancy, the body produces more hormones. These can make it harder for glucose in the blood to enter the cells. Blood glucose rises; this is known as gestational diabetes. It usually develops in the second half of pregnancy and generally goes away after birth.
A glucose tolerance test is usually performed between weeks 24 and 28 of pregnancy. Blood glucose is measured before and after drinking a glucose solution.
If diet and physical activity are not enough, insulin can lower blood glucose levels. Around one in six to eight women with gestational diabetes needs it. Insulin does not cross the placenta to the baby. Treatment is usually no longer needed after birth.
