The survival rate of fetal generalized hydrops is not high. Fetal generalized edema is a disease caused by the accumulation of extracellular fluid in the fetus, which is dangerous and it is recommended to terminate the pregnancy under the diagnosis of a doctor. Fetal generalized edema has a high mortality rate of 82% to 93%, and is usually caused by diseases of the fetus, the placenta, or the mother, and manifests itself as a large amount of fluid in the fetal abdominal and thoracic cavities, or fluid in soft tissues throughout the body of the fetus. It may be caused by chromosomal abnormalities or malformations of the fetus itself, and there is usually no treatment, so women should terminate the pregnancy as soon as possible under the diagnosis of a doctor. During pregnancy, women should avoid exposure to harmful substances and maintain a good mood. It is important to maintain a balanced diet during normal life so that the fetus can grow better. Fetal hydrops may endanger the health of the pregnant woman and there is usually no cure for fetal hydrops, so it is necessary to terminate the pregnancy on the advice of a doctor.
