What is the term for a pregnancy that lasts longer than 42 weeks?

A pregnancy that lasts longer than 42 weeks is referred to as a post-term pregnancy. This terminology is essential in maternal health, as it indicates potential risks for both the mother and the fetus. Post-term pregnancies can lead to complications such as increased chances of cesarean delivery, fetal distress, and other issues related to placental function and amniotic fluid levels.

Understanding this term is crucial for health professionals in monitoring and managing pregnancies, particularly as the due date approaches. The other options describe different stages or terminologies related to pregnancy duration: preterm refers to pregnancies that deliver before 37 weeks, full-term encompasses pregnancies that last between 39 to 40 weeks, and term generally refers to pregnancies lasting from 37 to 42 weeks. Each term outlines specific guidelines and implications for maternal and fetal health care.
