What does it mean when a 7-month pregnancy stops developing and the fetus dies in the womb?

Fetal death in utero at seven months of pregnancy is generally caused by factors such as umbilical cord knots, placental abnormalities, or chromosomal abnormalities. The details are as follows:

1. Umbilical Cord Abnormalities

If the umbilical cord becomes knotted, prolapsed, twisted, or wraps around parts of the fetus's body, it may lead to fetal asphyxiation. This condition is often accompanied by symptoms such as bleeding, abdominal pain, and abnormal fetal movements.

2. Placental Abnormalities

The placenta is the tissue responsible for providing nutrients to the fetus. If abnormalities occur—such as placenta previa or placental abruption—the placenta may fail to supply adequate oxygen and blood flow to the fetus, resulting in fetal death and intrauterine fetal demise after seven months of pregnancy.

3. Chromosomal Abnormalities

Chromosomal abnormalities can cause delayed fetal development and severe malformations. Additionally, if the fetus is infected in the uterine cavity by pathogenic microorganisms such as bacteria or viruses, or if there is blood type incompatibility between the fetus and mother leading to fetal hemolysis, these conditions may result in intrauterine fetal death at seven months of gestation.

Besides the above common causes, conditions such as hypertension, diabetes, and cardiovascular diseases may also contribute to this complication. It is recommended to undergo regular prenatal checkups to monitor fetal development. If intrauterine fetal demise occurs, prompt medical intervention is advised to prevent harm to the mother’s health.
