Why does childbirth cause heavy bleeding?

In our daily life, we eat a lot of food, face tremendous pressure, and have some bad habits, which may lead to some diseases. For many minor diseases, they can be cured as long as the symptoms are treated. However, some diseases are very scary and may even threaten life safety when they occur. Heavy bleeding during childbirth is a very dangerous thing.

Too much mental stress:

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.

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.

Uterine atony

We should be aware that sometimes even though the placenta has been expelled and the uterus has relaxed, a large amount of blood accumulates in the uterine cavity, but there is only a small amount of vaginal bleeding, and the mother has symptoms of excessive blood loss. Therefore, in addition to paying close attention to the amount of vaginal bleeding after delivery, we should also pay attention to the contraction of the uterus. The amount of vaginal bleeding visually estimated is much less than the actual amount of blood loss, so it must be collected and measured using a curved tray. If there is uterine atony before delivery and excessive bleeding during and after placental delivery, the diagnosis should not be difficult, but one must be alert to the aforementioned occult postpartum hemorrhage and the possible co-existence of birth canal laceration or placental factors.

Coagulation disorders:

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