Which of the following can contribute to postpartum hemorrhage?

Postpartum hemorrhage is often associated with various risk factors, and an over distended uterus is a significant contributor to this condition. An over distended uterus can result from multiple pregnancies, large fetal size (macrosomia), or excessive amniotic fluid (polyhydramnios). When the uterus is over distended, it may not contract effectively after delivery, which can lead to increased blood loss. Effective uterine contractions are crucial for constricting the blood vessels that supply the placenta and preventing excessive bleeding.

Other factors contributing to postpartum hemorrhage can include uterine atony (the failure of the uterus to contract), retained placental fragments, and trauma during delivery. Understanding the relationship between uterine distention and the risk of hemorrhage helps in monitoring and managing patients during the postpartum period.

Dehydration, excessive weight gain, and increased exercise are less directly related to the risk of postpartum hemorrhage. While dehydration can lead to complications, it is not a primary cause of hemorrhage. Similarly, while excessive weight gain may affect overall health, it does not directly result in an increased risk of postpartum hemorrhage compared to uterine distention. Increased exercise is generally encouraged postpartum as it supports recovery and overall health, with no direct connection to
