Causes of uterine fluid accumulation during pregnancy

Uterine effusion is also called uterine fluid. In some pregnant women, ultrasound examination results show uterine effusion. Is uterine effusion confirmed as threatened abortion? How to judge whether uterine effusion is physiological or pathological? Does uterine effusion have any effect on the fetus?

What is the cause of uterine fluid accumulation during pregnancy?

Threatened abortion should be ruled out first

If uterine fluid is found, threatened abortion should be ruled out first. It is necessary to consider whether it is related to the implantation site of the fertilized egg. If the implantation is not good, it is what we call threatened abortion. Another type of uterine fluid is normal. Within three months of pregnancy, due to poor conjunctival adhesion, periodic bleeding will occur, but the amount is small. Therefore, these situations should be considered during diagnosis.

Uterine fluid is divided into physiological and pathological

The causes of intrauterine fluid accumulation during pregnancy are divided into physiological and pathological. Physiological intrauterine fluid accumulation during pregnancy refers to periodic bleeding. Pathological intrauterine fluid accumulation during pregnancy includes threatened abortion (i.e. poor implantation of the fertilized egg), uterine dysplasia (such as uterine malformation, endometrial dysplasia, etc.), insufficient hormone levels (i.e. poor ovarian function), infectious factors (such as pelvic inflammatory disease, vaginitis, etc.) and immune rejection (including autoimmunity and alloimmunity).

Immune factors are also one of the causes

Immune factors can cause intrauterine fluid accumulation, including alloimmunity and autoimmunity. Alloimmunity means that the body has no antibodies to the embryo, so the antibodies are negative. Immunity diagnosis and treatment should be done before pregnancy until it is positive. If it is autoimmunity, treatment should be strengthened after pregnancy. Regardless of the type of immunity, blood flow blockage and blood flow reduction can easily lead to fetal growth retardation. If the implantation site is not formed well and affects fetal development, blood coagulation should also be tested.

Can uterine fluid lead to miscarriage?

If there is bleeding, it is easy to be infected with bacteria and induce miscarriage

In principle, as long as the pregnant woman has bleeding symptoms, she should go to the hospital for further examination. The reason for this treatment is that if there is bleeding, it is easy to get infected. Even if it is not an infectious abortion, it may be induced by infection.
