Placental Wound Bleeds When Bandage Fails

Birth is like ripping a large sticker off your arm—the placenta leaves behind a raw, bleeding wound where spiral arteries fed it for nine months. Normally, the uterus is like a fist that clamps down hard around that wound, squeezing the arteries shut (hemostasis). The clotting system then forms a fibrin scab sealing the raw spot. But if the fist stays relaxed (atony), the wound bleeds like an open tap. If someone tears the skin pulling the sticker off (genital laceration), blood pours from the torn vessel even if the fist tries to squeeze. If pieces of sticker stay stuck inside (retained placenta), they block the fist from closing all the way and rot into infected pus. If the blood cannot clot properly (coagulopathy), no scab forms and bleeding never stops. If bacteria grow in the rotting tissue and seep into the bloodstream (endometritis → sepsis), toxins trigger shock—blood vessels open wide, pressure crashes, and organs fail. If blood pressure stays dangerously high (preeclampsia), the injured vessel lining leaks and bleeding happens in the brain and liver. Each breakdown points to the same moment: the placental wound was not sealed.
