What is the meaning of intrauterine growth restriction?
Intrauterine growth restriction (IUGR) refers to the poor growth of a baby while in the mother’s womb during pregnancy.
How is intrauterine growth restriction diagnosis?
Accurate dating early in pregnancy is essential for a diagnosis of IUGR. Ultrasound biometry is the gold standard for assessment of fetal size and the amount of amniotic fluid. Growth restriction is classified as symmetric and asymmetric. A lag in fundal height of 4 cm or more suggests IUGR.
What is the difference between IUGR and FGR?
In this Article Fetal growth restriction (FGR), formerly called intrauterine growth restriction (IUGR), refers to a condition in which an unborn baby is smaller than it should be because it is not growing at a normal rate inside the womb. Mild FGR usually doesn’t cause long-term problems.
What causes intrauterine growth restriction?
The most common cause of FGR is a problem before birth in the placenta (the tissue that carries oxygen, food, and blood to the baby). Birth defects and genetic disorders can also cause FGR. A baby also may develop FGR if the mother: Has an infection.
What is the meaning of fetal growth?
Fetal growth is dynamic and serial measurements at 2 to 3 week intervals are needed to define normality and abnormality. Normal growth is defined by measurements of the head (biparietal diameter, head circumference), abdomen circumference (AC) and femur length within the normal ranges for gestation.
What is fetal growth and development?
Fetal Development: Stages of Growth. Within 24 hours after fertilization, the egg that will become your baby rapidly divides into many cells. By the eighth week of pregnancy, the embryo develops into a fetus. There are about 40 weeks to a typical pregnancy. These weeks are divided into three trimesters.
Can fetal growth restriction improve?
Although it is not possible to reverse IUGR, some treatments may help slow or minimize the effects, including: Nutrition: Some studies have shown that increasing maternal nutrition may increase gestational weight gain and fetal growth.
What can cause slow fetal growth?
Growth restriction early in pregnancy (early onset) happens because of chromosome problems in the baby. It also happens because of disease in the mother, or severe problems with the placenta. Growth restriction is called late onset if it happens after week 32 of the pregnancy. It is often linked to other problems.
What are the risk factors for fetal growth restriction?
The main factors assessed in clinical practice include: maternal factors [socioeconomic status, weight (very low and also increased body mass index), smoking, use of recreational drugs, advanced maternal age, nulliparity, history of gestational hypertension, family history of IUGR or previous IUGR pregnancy, previous …
What is a fetal growth ultrasound?
Your maternity care provider has referred you for an ultrasound scan to assess the baby’s size and the amniotic fluid volume. This type of ultrasound scan is referred to as a fetal growth scan.
