SGA is based on one measurement taken at one point in time.A fetus with IUGR always shows slower than normal growth in the uterus.

These various measures can then be compared with the time of gestation and if the value falls below 10% of what is expected for that time of development, then SGA can be confidently diagnosed.There are many reasons for a baby to be SGA. IUGR. An additional challenge is the difficulty in differentiating between the fetus that is constitutionally small and fulfilling its growth potential and the small fetus that is not fulfilling its growth potential because of an underlying pathologic condition.

There are several other causes of IUGR, including a woman who uses drugs or There is an increased mortality rate of fetuses and babies that have IUGR, and many of the complications depend on the cause of the condition.

Other complications that may arise include polycythemia and hypoglycemia. -IUGR vs. SGA: IUGR refers to deviation and reduction in expected fetal growth pattern.


An abnormality of the uterus and malnutrition can also result in a small for gestational age infant. Accurate dating early in pregnancy is essential for a diagnosis of IUGR. Multiple adverse conditions inhibit normal fetal growth potential.

An SGA baby does not always show slower than average growth.The birth weight of a baby with IUGR is not always lower than normal, but the birth weight of an SGA baby is always lower than normal.The IUGR condition is always pathological; it is always due to a problem in utero. Some fetuses may die in utero from the condition. One of these monitoring techniques is an umbilical artery Doppler. A baby may be SGA if the mother smoked, drank or did drugs during the pregnancy.

Physically these infants when born appear to be normal in appearance except for appearing thin and having little fat and muscle tissue. with uncertainty surrounding the optimal management and timing of delivery for the growth-restricted fetus.

She has received a PhD in Quantitative Biology from the University of Texas at Arlington as well as an AAS Degree in Information Network Specialist and an AAS in Computer Information Systems, at Bossier Parish Community College in Louisiana.Her skills lie in research and writing for a range of educational levels and teaching various Biology classes.

First there is restriction of weight
