Definition

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

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

Postterm pregnancy can increase the risk of certain complications. These include labor problems, cesarean section, infection, meconium aspiration, and stillbirth.

Diagnosis

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

Management of postterm pregnancy may include induction of labor, fetal monitoring, and cesarean section if necessary.
