FGR has many possible causes. Chronic Fetal Hypoxia. Symmetrical IUGR is when the baby is growing proportionally and is lagging behind. Types of IUGR Infants with IUGR are often classified as having symmetrical (head circumference, length and weight equally affected) or asymmetrical (with relative head growth sparing) growth restriction. . C. Cmack16. The placenta is the tissue that joins the mother and fetus, carrying oxygen and nutrients to the baby and permitting the release of waste products from the baby. The extent of the health problems depends upon the cause and severity of the growth restriction. Intrauterine growth restriction, sometimes referred to as fetal growth restriction or small for gestational age (SGA), is a condition in which an unborn baby is not growing at a This can be due to, There are basically two different types of fetal growth restriction: Symmetric or primary growth restriction is characterized by all internal organs being reduced in size. Symmetric IUGR accounts for 20% basically symetrical iugr implies problem in the initial phase of pregnancy and asymmetrical means in the later part of prognancy. Poor nutritional status and frequent pregnancies are common pre-disposing conditions in addition to obstetric and medical problems during pregnancy.

IUGR happens when the fetus is not getting the required amount of nutrients or oxygen. Most neurons are developed by the 18th week of gestation, therefore the fetus with symmetrical IUGR is more likely to have permanent neurological sequelae. week of gestation there was a significant decrease of FM rate in both groups of IUGR which was more pronounced in the symmetrical group. Intrauterine growth retardation (IUGR) implies that intrauterine growth has been inhibited and that the fetus has not attained its growth potential. Intrauterine growth restriction results when a problem or abnormality prevents cells and tissues from growing or causes cells to decrease in size.
A common cause is a problem with the placenta.
IUGR is noted to affect approx- symmetrical reduction of the organ size and a symmetrical IUGR fetus. This affects heart or respiratory disease.

Diseases such as high blood pressure and heart disease may cause FGR, as can infections like rubella, cytomegalovirus, syphilis or toxoplasmosis.
