What does bleeding during pregnancy mean?

Pregnancy, also known as gestation, may involve vaginal bleeding caused by physiological factors such as excessive physical activity, or by pathological factors such as placental abruption and threatened abortion. A detailed analysis is as follows:

1. Physiological Factors

In early pregnancy, embryo implantation is not yet stable. If a pregnant woman engages in excessive physical activity within a short period, it may cause abnormal uterine contractions, potentially leading to vaginal bleeding during pregnancy. Minor bleeding is generally considered normal. It is recommended to rest in bed and avoid overexertion.

2. Pathological Factors

1. Placental Abruption

In late pregnancy, if the pregnant woman's abdomen suffers external impact, the uterus may suddenly stretch, causing separation between the uterine wall and placenta. This can rupture capillaries, allowing blood to flow out through the vagina, resulting in bleeding. Immediate hospitalization is advised for monitoring of vital signs and ensuring airway patency. In some cases, cesarean delivery may be necessary to induce early childbirth.

2. Threatened Abortion

If a pregnant woman frequently stays up late or consumes stimulants such as coffee during pregnancy, the fetus may be subjected to abnormal stimulation, impairing normal development. This could lead to partial embryonic tissue detachment and necrosis, causing this condition. Dilation and curettage (D&C) is recommended to remove residual embryonic tissue.

Additionally, ectopic pregnancy may also be a cause. Daily attention should be paid to personal hygiene, and exposure to radiation and other irritants should be minimized.
