Multiple pregnancy overstretches the uterus, which increases the risk
of heavy bleeding (hemorrhage) into the abdomen or from the vagina. Hemorrhage
can occur at any time before, during, or after (postpartum) delivery, but it is
more common in the postpartum period.
Bleeding from the uterus is controlled by how well the uterine
muscles contract after childbirth. Treatment to control bleeding commonly
includes massaging the uterus and giving oxytocin, a hormone medicine that
helps the uterine muscles contract. Other medicines may also be used.
If you hemorrhage heavily after childbirth, you may need a blood
transfusion, particularly if you have been
anemic during pregnancy.
