Understanding gestational diabetes

Why does it occur?

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.

How is it diagnosed?

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.

Insulin if needed: 10–15%

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.
