What factor could indicate an increased risk for postpartum hemorrhage?

Multiple pregnancies, such as twins or triplets, can significantly increase the risk for postpartum hemorrhage. This is attributed to several factors associated with carrying multiple fetuses. The uterus is not only larger but also experiences more distension, which can lead to difficulties in contraction after delivery. Effective uterine contractions are essential to clamp down on blood vessels following the separation of the placenta. If the uterus does not contract effectively, there is an increased risk of hemorrhage.

In contrast, a single infant delivery typically presents a lower risk of postpartum hemorrhage, as the uterus is better able to contract effectively. Similarly, a short labor duration generally means the body has not been under prolonged stress, which can also positively impact the risk for hemorrhage. Prolonged breastfeeding, while associated with numerous benefits, does not relate directly to increasing the risk of hemorrhage post-delivery. Thus, multiple pregnancies stand out as a significant factor contributing to this risk.
