Nutrition supply The malnutrition of pregnant women has a very direct impact on the fetus. Because all nutrition is obtained by the mother when the fetus is in the mother, the nutritional status of pregnant women directly affects the level of fetal growth and development. If there is folic acid deficiency or iodine deficiency, these conditions will directly lead to fetal abortion or dystocia, stillbirth, and also lead to some neural tube malformations. Improving nutritional status, establishing healthy eating habits and implementing the whole pregnancy can promote the normal growth and development of the fetus, further reduce the risk of growth restriction and obesity of the offspring, and promote the cognitive and behavioral development of the offspring.
If the placental transport of nutrients is abnormal, such as small placenta or sail placenta, the blood flow of uterus and placenta will be reduced, resulting in insufficient blood supply for infants. Placental dystrophy can directly affect the fetus, leading to intrauterine ischemia, developmental retardation, oligohydramnios in pregnant women, and placental aging and calcification due to decreased nutritional transmission ability. This situation is more common in pregnant women with overdue pregnancy, gestational diabetes, pregnancy-induced hypertension and gestational diabetes complicated with nephropathy. Early shallow implantation of placenta can cause placental malnutrition, which in turn leads to the release of placental special factors into the blood, causing a series of maternal and fetal complications. Therefore, placental malnutrition in pregnant women can lead to pregnancy-induced hypertension and hypoproteinemia. Umbilical cord factor Umbilical cord factor, too long, too thin, twisted and knotted umbilical cord will affect the baby's blood supply, leading to growth restriction.
Pregnant women should pay more attention to rest, avoid fatigue and pay attention to diet. Don't eat hawthorn, longan, lychee, crab and other things that can easily cause uterine contraction. During pregnancy, FGR fetuses need to be evaluated by doctors by counting fetal movements, ultrasound and electronic fetal heart monitoring to confirm whether the fetuses are suitable for continued pregnancy and normal delivery. If the scores are poor for many times, it means that the fetal malformation rate is high, and pregnancy is usually not recommended. If the fetus is in good condition, pregnant women can give birth normally under the guidance of a doctor.
