Multiple Gestation

Abstract

Multiple pregnancies mean when the woman carries more than one fetus at a time. Multiple pregnancy, multiple gestation, and multifetal pregnancy are synonyms. These can be twins, triplets, quadruplets, or more. These types of pregnancy have become one of the most common high-risk pregnancies encountered by obstetricians. It is associated with an increased risk of both maternal and perinatal morbidity and mortality. The incidence of multiple pregnancies has risen significantly over the last four decades, primarily due to increased use of ovulation induction drugs. The symptoms and signs of multiple pregnancies include excessive nausea and vomiting, larger uterus than expected for the date of pregnancy, and excessive weight gain. The aim of this chapter is to discuss the occurrence, causes, epidemiology, maternal and perinatal morbidity and mortality, antepartum, and intrapartum management of multiple pregnancies.
