At which gestational age is the risk of placental insufficiency significantly increased?

The correct answer is associated with the gestational age of 42 weeks. At this stage, the placenta is often reaching the end of its functional capacity. A prolonged gestation can lead to placental aging and a decrease in its efficiency in providing nutrients and oxygen to the fetus, resulting in an increased risk of placental insufficiency, which can affect fetal development and lead to complications such as intrauterine growth restriction.

Furthermore, as gestational ages extend beyond 42 weeks, there are compounded risks associated with the placenta, including a higher likelihood of cord accidents, meconium aspiration, and other adverse outcomes. This is why monitoring and interventions may become necessary when pregnancies extend past the typical term.

Understanding these risks emphasizes the importance of careful assessment and management in pregnancies approaching and surpassing the 42-week mark, helping ensure better maternal and fetal outcomes.
