What is extrauterine growth restriction?
Extrauterine Growth Restriction (EUGR) refers to inadequate growth during hospitalization. Current definitions for EUGR are varied and can be classified as cross-sectional (weight at a given t-time <10th centile) or longitudinal (weight loss between birth and a given t-time >1SD).
What is IUGR PDF?
Intrauterine growth restriction (IUGR), a condition that occurs due to various reasons, is an important cause of fetal and neonatal morbidity and mortality. It has been defined as a rate of fetal growth that is less than normal in light of the growth potential of that specific infant.
What are the types of fetal growth restriction?
The two types of IUGR are: symmetrical IUGR: all parts of the baby’s body are similarly small in size. asymmetrical IUGR: the baby’s head and brain are the expected size, but the rest of the baby’s body is small.
What is postnatal growth restriction?
Postnatal growth restriction was defined as a weight z-score at 36 weeks <-1.5 or treated as a continuous variable (fall in weight z-scores from birth to 36 weeks postmenstrual age). Results: Weight z-scores fell in almost all patients (98.8%), and 44.1% had z-scores <-1.5 at 36 weeks.
Why is IUGR important?
Intrauterine growth determines the perinatal, postnatal, and adult life development. IUGR is associated with increased risk of development in adult life of metabolic diseases including but not limited to hypertension, diabetes, obesity, dyslipidemia, and the metabolic syndrome.
What causes IUGR?
IUGR has various causes. The most common cause is a problem in the placenta (the tissue that carries food and blood to the baby). Birth defects and genetic disorders can cause IUGR. If the mother has an infection, high blood pressure, is smoking, or drinking too much alcohol or abusing drugs, her baby might have IUGR.
What are the risks of IUGR?
IUGR is associated with increased risk of premature birth; increased morbidity among premature neonates, including necrotizing enterocolitis; low Apgar score; hypoxic brain injury and its long-term sequelae; the need for respiratory support and chronic lung disease; retinopathy of prematurity; prolonged neonatal …
What is the most common cause of fetal 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 happens if baby is growth restricted?
FGR can cause many serious complications. Your baby may need to be delivered early and stay in the hospital. Your baby may have trouble breathing, infections, and other problems. Stillbirths and death may occur.
What happens with fetal growth restriction?
If your baby has FGR, there is an increased risk of complications in pregnancy. Sadly, this can include stillbirth. But your healthcare team will monitor the baby’s growth and wellbeing closely to reduce the risk of this happening. They will also talk to you about the best time for you to give birth.
What problems can IUGR cause?
Intrauterine growth restriction (IUGR) can lead to infants being born small for gestational age (SGA). SGA is associated with increased neonatal morbidity and mortality as well as short stature, cardiovascular disease, insulin resistance, diabetes mellitus type 2, dyslipidemia and end-stage renal disease in adulthood.
How do you prevent IUGR?
Prevention
- Do not drink alcohol, smoke, or use recreational drugs.
- Eat healthy foods.
- Get regular prenatal care.
- If you have a chronic medical condition or you take prescribed medicines regularly, see your provider before you get pregnant. This can help reduce risks to your pregnancy and the baby.
How is growth restriction diagnosis?
A diagnosis of FGR is based on the difference between actual and expected measurements at a certain gestational age. Doppler ultrasound. You may also have this special type of ultrasound to diagnose FGR. Doppler ultrasound checks the blood flow to the placenta and through the umbilical cord to the baby.
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.
How do you treat IUGR?
You can do five important things to help your baby grow big enough before it’s born:
- If you smoke—quit now.
- If you drink alcohol—quit now.
- If you use illegal drugs—quit now.

Is IUGR a high risk pregnancy?
Babies with IUGR are at greater-than-normal risk for a variety of health problems before, during and after their birth. These problems include low oxygen levels while in the womb, a high level of distress during labor and delivery, and an increased risk of infectious disease after birth.
Can babies with IUGR be normal?
In accurately dated pregnancies, approximately 80-85% of fetuses identified as being IUGR are constitutionally small but healthy, 10-15% are ‘true’ IUGR cases, and the remaining 5-10% of fetuses are affected by chromosomal/structural anomalies or chronic intrauterine infections [5].
Can Babies with IUGR be normal?
Who is at risk for IUGR?
Pregnancies that have any of the following conditions may be at a greater risk at developing IUGR: Maternal weight less than 100 pounds. Poor nutrition during pregnancy. Birth defects or chromosomal abnormalities.
What is the most common cause of IUGR?
Chronic hypertension is the most common cause of IUGR.
What causes growth restriction?
Intrauterine growth restriction results when a problem or abnormality prevents cells and tissues from growing or causes cells to decrease in size. This may occur when the fetus does not receive the necessary nutrients and oxygen needed for growth and development of organs and tissues, or because of infection.
