A 34 week placenta showing restriction could be an abnormality in the development of the placenta itself. Generally, the placenta is the pathway that primarily maintains the function and development of the fetus. If a pregnant woman at 34 weeks of pregnancy undergoes an ultrasound that suggests that the placenta shows restriction, then consider the possibility that there is a problem with the development of the placenta itself. If this occurs, it is necessary to further check the development of the fetus, as well as the blood flow of the umbilical cord and the amniotic fluid, and to strengthen the labor and delivery examination, so as to avoid that the function of the placenta may be affected due to the restriction of the placenta, which may affect the development of the baby. If the ultrasound examination indicates that the placenta is limited, but the development of the fetus is normal, then it can be observed for the time being. If the development of the fetus slows down or there are other abnormalities, further examination or symptomatic treatment is needed.
