Which of the following is a cause of secondary postpartum hemorrhage?

Correct option is C

Ans. (c) Sol. The presence of retained cotyledons in the uterus is one of the most common causes of secondary postpartum hemorrhage. When fragments of the placenta, called cotyledons, are not expelled after delivery, they can lead to ongoing bleeding.
Explanation of each option:
· (a) Laceration of the lower genital tract – Incorrect. This is typically a cause of primary postpartum hemorrhage, not secondary.
· (b) Involution of the uterus – Incorrect. Involution refers to the process by which the uterus returns to its normal size after birth. Delayed involution can cause bleeding, but it’s not the most common cause of secondary hemorrhage.
· (c) Presence of retained cotyledons – Correct. The presence of retained cotyledons is a key cause of secondary postpartum hemorrhage, leading to prolonged or excessive bleeding due to incomplete expulsion of the placenta after birth.
· (d) Presence of hematological disorders in the mother – Incorrect. While hematological disorders can contribute to postpartum hemorrhage, they are typically a predisposing factor rather than a direct cause of secondary hemorrhage.
