What is the main concern for a woman diagnosed with gestational diabetes?

The primary concern for a woman diagnosed with gestational diabetes is indeed the risk of macrosomia in the newborn. Gestational diabetes leads to elevated blood glucose levels, which can cause the fetus to receive excess glucose. This can result in increased fetal growth, leading to macrosomia, where a newborn is significantly larger than average. Macrosomia poses various challenges during delivery, such as increased risk of birth injuries, the necessity for a caesarean section, and potential long-term health issues for the child, such as obesity and diabetes later in life.

This connection highlights why monitoring and managing blood sugar levels during pregnancy is crucial to mitigate the risk of macrosomia, ensuring both maternal and fetal health.
