Postpartum flooding

Severe bleeding after childbirth. Postpartum flooding is attributable to a) damage to the thoroughfare (chōng), controlling (rèn), and uterine vessels, b) damage through physical exertion before the channels have returned to normal after childbirth, c) retention of the afterbirth causing obstruction of the thoroughfare, controlling, and uterine vessels, or d) sex too soon after childbirth. For treatment, see flooding and retention of the afterbirth.
