Multiple birth

Multiple births occur when more than one fetus is carried to term in a single pregnancy. The offspring resulting from multiple pregnancies can include twins, triplets, quadruplets, quintuplets, and more.

Definition and Types

A multiple gestation is a pregnancy with more than one fetus, leading to a multiple birth upon delivery. The types of multiple births are named based on the number of offspring:

• Twins - Two offspring
• Triplets - Three offspring
• Quadruplets - Four offspring
• Quintuplets - Five offspring

Higher order multiples - Six or more offspring

Factors Influencing Multiple Births

Multiple births can occur naturally or as a result of fertility treatments such as in vitro fertilization (IVF). Factors influencing the likelihood of multiple births include maternal age, family history, previous multiple births, and certain medical conditions.

Risks and Complications

Multiple pregnancies carry a higher risk of complications, both for the mother and the fetuses. These include preterm labor, gestational diabetes, preeclampsia, and neonatal intensive care unit (NICU) admission for the newborns.

Management and Care

Management of multiple pregnancies requires careful prenatal care to monitor the health of both the mother and the fetuses. This often includes more frequent prenatal visits, tests, and potentially, a planned delivery.
