Why is post-term delivery high risk?
Why is post-term pregnancy a concern? Post-term pregnancy is associated with longer labors and operative delivery (forceps or vacuum-assisted birth). Mothers are at increased risk for vaginal birth trauma due to a large baby. Cesarean delivery is twice as likely in a post-term pregnancy because of the size of the baby.
What is a risk factor for Postterm pregnancy?

They are often used to describe the features of a neonate who appears to have been in utero longer than 42 weeks of gestation.
