Postterm pregnancy refers to a condition where a woman has been pregnant for at least 42 weeks, surpassing her estimated due date. There are a few different synonyms for this condition, including prolonged pregnancy, overdue pregnancy, and post-dates pregnancy. Other related terms might include postmaturity syndrome, which refers to the health risks associated with prolonged gestation, and post-term birth, which describes the delivery of a baby after the 42-week point. While postterm pregnancies are not uncommon, they can increase the risk of complications for both mother and baby, including fetal distress, stillbirth, and labor difficulties. For this reason, women with postterm pregnancies are often closely monitored by healthcare providers and may be induced or undergo a cesarean section to ensure a safe delivery.
