Postterm pregnancy is a condition where a pregnancy lasts 42 weeks or more. This condition can lead to complications for both the mother and the baby.
Definition[edit]
A pregnancy is considered postterm if it lasts 42 weeks or more. This is calculated from the first day of the last menstrual period.
Causes[edit]
The exact cause of postterm pregnancy is unknown. However, some factors that may contribute to this condition include a previous postterm pregnancy, being a first-time mother, and male fetus.
Risks[edit]
Postterm pregnancy can increase the risk of certain complications. These include labor problems, cesarean section, infection, meconium aspiration, and stillbirth.
Diagnosis[edit]
Postterm pregnancy is diagnosed based on the date of the last menstrual period. If this date is uncertain, an ultrasound may be used to estimate the gestational age of the fetus.
Management[edit]
Management of postterm pregnancy may include induction of labor, fetal monitoring, and cesarean section if necessary.
