In a post-term pregnancy, which is defined as continuing beyond 42 weeks of gestation, there are specific risks that can pose challenges to both the mother and the fetus. One of the primary risks is placental insufficiency, where the placenta may not function effectively, leading to inadequate oxygen and nutrient supply to the fetus. This can result in a compromised fetal environment, potentially causing a range of complications.

Fetal macrosomia, which refers to the fetus being significantly larger than average, is also a notable risk during post-term pregnancies. This condition can complicate delivery, increasing the likelihood of birth injuries or the need for cesarean delivery. The combination of placental insufficiency and fetal macrosomia highlights the physiological changes and challenges associated with prolonged gestation, making this choice the most relevant answer regarding the primary risks in such scenarios.

In contrast, while gestational diabetes and hypertension are serious conditions that can occur during pregnancy, they are not specifically associated with post-term pregnancies as primary risks. Preterm labor and excessive weight loss are distinctly opposite concerns to post-term situations. Finally, while neonatal jaundice and respiratory distress can occur in newborns, they are not uniquely attributable to being post-term but can manifest in various other circumstances surrounding birth.
