How is "post-term pregnancy" defined?

Post-term pregnancy is defined as a pregnancy that extends beyond 42 weeks of gestation. This definition is crucial for obstetric and maternal-fetal care, as pregnancies that go past the standard 40-week gestational period may pose increased risks for both the mother and the fetus.

In a post-term pregnancy, there can be concerns about the placental function deteriorating, leading to potential fetal distress, reduced amniotic fluid, and increased likelihood of meconium aspiration. Therefore, medical professionals closely monitor such pregnancies as they approach and exceed this 42-week mark to manage these potential risks effectively.

Understanding the definitions of different pregnancy stages is essential for healthcare providers to ensure the well-being of both the mother and the baby, and to make informed decisions regarding labor induction or other interventions if necessary.
