Postpartum hemorrhage is usually defined as bleeding greater than 1,000 ml 24 hours after a cesarean section or 500 ml 24 hours after a natural birth, which is classified as postpartum hemorrhage, and is relatively common in postpartum hemorrhage. Although some women have met the diagnostic criteria for postpartum hemorrhage, essentially, women have a bleeding reserve in late pregnancy, meaning that there is a reserve of about 800 ml of blood in late pregnancy. If the bleeding is less than 800 milliliters over a 24-hour period, it will not cause much harm to the woman in most cases as long as the bleeding can be stopped in a timely manner. However, if the bleeding reaches 800 ml to 1,000 ml in 24 hours and this is not well controlled, it will continue to bleed, leading to uncontrollable bleeding which will have serious consequences for most women. If a woman continues to have clots after a few days of rest, she should consult a doctor for medical attention.
