 This review examined the effects of primary postpartum hemorrhage, PPH, on women's long-term physical and mental health. It found that women who experienced PPH were at higher risk of developing chronic physical and psychological health issues such as post-traumatic stress disorder, PTSD, cardiovascular disease, and other conditions. Additionally, the review found that these risks were greater when the woman experienced a severe PPH, as indicated by a blood transfusion or hysterectomy. Furthermore, there was limited evidence regarding the effects of PPH on partners, although some studies suggested that they could also develop PTSD symptoms if they witnessed the event. Overall, this review highlights the need for further research into the long-term effects of PPH on women and their partners.
