Children with growth restriction may be born with defects. There are many factors that can cause fetal growth restriction, some of which are caused by genetic or chromosomal abnormalities in the fetus itself, so certain fetuses are born with defects. Fetal growth restriction is defined as an estimated fetal weight that is less than the 10th percentile of gestational age at the week of gestation. It may be caused by maternal paranoia, gestational hypertension, fetal genetic or chromosomal structural abnormalities, umbilical cord torsion, etc. Growth restriction refers to the limitation of fetal growth potential, and growth backwardness may occur after birth. If you find fetal growth restriction, you should consult a doctor in time. Under the judgment of a professional doctor, different treatments will be taken according to different causes and timely gestational weeks in order to promote better growth of the fetus.
