PPH can be caused by several factors, often summarized using the "4 Ts":
Tone: Uterine atony, where the uterus fails to contract effectively. Trauma: Injury to the birth canal, including lacerations or uterine rupture. Tissue: Retained placental fragments that prevent the uterus from contracting. Thrombin: Coagulopathies or blood clotting disorders.
