What is a potential consequence of untreated gestational diabetes?

When gestational diabetes is not treated, one significant consequence is an increased likelihood of cesarean delivery. This condition can lead to excessive fetal growth, known as macrosomia, due to elevated glucose levels in the mother's blood, which can provide excess energy to the developing fetus. As a result, larger babies may present challenges during delivery, leading healthcare providers to opt for a cesarean section to ensure the safety of both mother and child.

In contrast, untreated gestational diabetes typically does not result in decreased fetal growth or contribute to low maternal blood pressure. Additionally, uterine rupture is not a commonly associated consequence of gestational diabetes. Thus, the option identifying an increased likelihood of cesarean delivery reflects a direct and clinically relevant outcome of failing to manage gestational diabetes effectively.
