Intrauterine Growth Restriction

Intrauterine growth restriction (IUGR) is condition which causes  poor growth of the fetus.  This condition specifically refers for those babies who are smaller than their normal size during gestation. This condition is also known as fetal growth restriction or small for gestational age (SGA).

Types of Intrauterine Growth Restriction (IUGR):

  • Systemic or Primary Intrauterine Growth Restriction: It is the condition in which all the internal organs of baby are reduced to a smaller size. This condition is found in 20 – 25% of the cases.
  • Asymmetric or Secondary Intrauterine Growth Restriction: It is the condition in which the head and brain of the developing baby is of the normal size, but the abdominal portion is smaller than normal. This condition can be evident only after the third trimester begins.

Causes of Intrauterine Growth Restriction ( IUGR):

  • The mother’s diagnosis of  heart disease or gestational diabetes
  • The mother’s weight is less than 100 pounds
  • Chromosomal abnormalities or birth defects
  • Pregnancy Induced Hypertension (PIH)
  • Abnormality in umbilical cord
  • Abnormality in placenta
  • Multiple pregnancies
  • Low levels of amniotic fluid

Risks to Baby Born With IUGR:

  • Hypoxia, or a lack of oxygen when baby is born
  • Meconium aspiration, which occurs when the baby swallows part of her first bowel movement. This can cause pneumothorax or development of bacterial pneumonia in the thorax region.
  • Hypoglycemia or low blood sugar
  • Polycythemia (increase in number RBCs)
  • Hyper viscosity or a condition in which the flow of blood is reduced due an increase in RBCs
  • Chances of motor and neurological disabilities increases
