Multiple pregnancy is defined as the development of more than one fetus in the uterus at the same time. The most common type is twins, which can be either dizygotic (from two separate eggs) or monozygotic (from one egg that splits). Diagnosis involves history, examination, ultrasound, and biochemical tests. Risks include preterm birth, low birthweight, preeclampsia, and prolonged labor. Management involves specialized antenatal care including diet, rest, and hospitalization later in pregnancy. During labor, careful monitoring is needed and a team should be prepared for complications like emergency c-section or bleeding. Postnatal care requires close observation of both mother and babies.
