The dead fetus has been in my belly for half a year.

For pregnant women, the most worrying thing is fetal death in the womb. This abnormal situation is a great blow to pregnant women. It is not only a physical blow, but also the psychological trauma that cannot be recovered for a long time. How long can a fetus stay in the womb? Doctors recommend that fetal death in the womb should be dealt with as soon as possible to avoid causing unnecessary harm to the pregnant mother.

How long can a fetus stay in the womb?

If the dead fetus stays in the uterine cavity for too long, it can cause blood clotting problems in the pregnant mother. About 80% of fetal death will result in miscarriage within 2-3 weeks. If the test tube embryo is not expelled 3 weeks after death, the test tube embryonic tissue will undergo degenerative changes and release thrombin into the pregnant mother's blood circulation, activating the coagulation factors in the blood vessels, causing local intravascular coagulation, and consuming coagulation factors such as fibrinogen and platelets in the blood. The chance of focal intravascular coagulation occurring in the fetus for more than 4 weeks in the uterine cavity increases significantly, which can cause severe bleeding during delivery. Therefore, once the death of the test tube embryo is diagnosed, effective measures should be taken as soon as possible, and surgical curettage should be performed, and the fetus should be closely observed to avoid complications.

Causes of fetal death in utero

1. Infection: including bacteria, viruses, toxoplasmosis and syphilis, etc., which can cause serious maternal illness and fetal infection, fetal intrauterine hypoxia or developmental malformations leading to fetal death.

2. Pregnancy complications or diseases: including hypertension, heart disease, diabetes, thyroid disease, diabetic nephropathy such as nephrotic syndrome, liver disease such as acute fatty liver of pregnancy, antiphospholipid antibody syndrome, genetic thrombophilia, blood cell alloimmunity, platelet alloimmunity and premature birth, etc. can all cause fetal death in the womb.

3. Embryo and umbilical cord abnormalities: Embryo and umbilical cord abnormalities that cause fetal death include maternal-fetal bleeding, embryo abnormalities, umbilical cord abnormalities, and embryo abnormalities in multiple pregnancies.

4. Fetal diseases: including somatic cell biological abnormalities such as Turners syndrome, trisomy 21, trisomy 18 and trisomy 13, as well as amniotic band syndrome and central nervous system defects. Risk factors for stillbirth include older age, obesity, smoking, a previous history of stillbirth, and lack of standardized prenatal testing.
