View source for B24. Overdue and postterm pregnancy

Overdue pregnancy refers to a pregnancy which has passed week 41+0 (day 287). Postterm pregnancy refers to pregnancy which has passed week 42+0 (day 294).

Postterm pregnancy is associated with several complications, due to the excessive foetal growth or due to placental insufficiency (as the placenta is unable to support the postterm foetus). Complications include oligohydramnios, intrauterine growth restriction, macrosomia, and meconium aspiration. There’s also a higher perinatal mortality.
