Excessive blood loss after childbirth can have several causes; the most common is:

One of the most important principles of effective health education is to involve the target audience in the planning process. By involving the target audience in the planning process, the nurse can gain a better understanding of their needs, priorities, and concerns related to health and wellness. This, in turn, can help the nurse develop education goals that are relevant, engaging, and effective at improving health outcomes.

Asking the formal leadership of a community what the learning needs are, using the expertise of professional nurses who are skilled at assessing needs, or interviewing physicians to determine the highest need based on diagnoses can all be useful strategies for gathering information about community health needs. However, none of these strategies are as effective at identifying the specific needs and priorities of the target audience as asking the target audience directly.

The most common cause of excessive blood loss after childbirth is the failure of the uterine muscle to contract firmly, which is also known as uterine atony. If the uterus does not contract effectively after delivery, it cannot properly close off the blood vessels that were connected to the placenta, leading to heavy bleeding. Uterine atony can occur due to various factors, such as prolonged labor, multiple births, or the use of certain medications during labor.
Other causes of excessive blood loss after childbirth include retained placental fragments, vaginal or vulvar hematomas, or unrepaired lacerations of the vagina or cervix, but these are less common than uterine atony.
