Once the baby is delivered and the placenta comes out, the effect of the placental hormones is removed. This usually puts an end to gestational diabetes. However, women who have had gestational diabetes may develop diabetes in the future, so it's important for them to maintain a healthy lifestyle and to keep their weight under control. They're also likely to develop gestational diabetes in subsequent pregnancies; this risk can be lowered by losing weight, eating healthfully, and being physically active.

A baby born to a woman with gestational diabetes may initially experience abnormal blood sugar levels, even if the disease was well controlled during pregnancy, so doctors will test the baby's blood and give insulin when needed. This is a temporary condition.
