What are the causes of heavy bleeding during childbirth?

Natural birth is the most natural way of childbirth and is very good for the natural development of the baby. However, it also puts the mother at greater safety risk and causes great pain to women, which is difficult for women to bear. The most common problem with normal childbirth is massive tissue bleeding, which can endanger life at any time. Let’s take a look at the causes of heavy bleeding during natural childbirth.

(1) Excessive mental tension: Some women are too nervous during childbirth, which leads to poor uterine contraction and is the main cause of postpartum hemorrhage. Under normal circumstances, when the placenta is detached from the decidua layer of the uterus, the blood sinuses on the detached surface open and some bleeding is common, but when the placenta is completely detached and discharged from the uterus, the bleeding decreases rapidly. However, if the mother is overly nervous or due to other reasons, the uterus may not contract well and the blood vessels may not close, heavy bleeding may occur. If the mother is overly nervous, the labor process is too long, the labor lasts too long, too many sedatives are used, or the anesthesia is too deep, it can also cause the placenta to contract weakly and heavy bleeding to occur.

For example, in cases of polyhydramnios, macrosomia, and multiple pregnancy. Due to excessive expansion of the uterus, the uterine fibers stretch excessively and cannot recover well after delivery; too many and too frequent births cause degeneration of uterine muscle fibers, increased connective tissue, reduced muscle fibers and weak contraction, etc., which is also one of the causes of postpartum hemorrhage.

(2) Retained placenta: Retained placenta is also one of the causes of heavy bleeding, including incomplete placental detachment and placental adhesion, which can also cause heavy bleeding.

(3) Coagulation dysfunction: If the mother suffers from blood disease or severe hepatitis, the consequences are also very serious and must be paid close attention to. When giving birth, you should go to a hospital with the necessary facilities to avoid accidents.

Therefore, mothers must undergo prenatal examinations. Mothers with a history of postpartum hemorrhage, bleeding tendencies such as blood diseases, hepatitis, and multiple curettages should be admitted to the hospital in advance to prepare for delivery, have their blood type checked, and have blood prepared to prevent any accidents during delivery. Postpartum hemorrhage is sometimes difficult to predict in advance and often occurs suddenly, so it is important to take good care of yourself: if bleeding is caused by weak uterine contractions, you should immediately massage the uterus to promote rapid uterine contractions, or compress the abdominal aorta to reduce the amount of bleeding.
