Intrauterine Growth Restriction, also commonly known as fetal growth restriction, is a medical condition characterized by poor growth of the baby in the mother's womb during pregnancy. The weight of the baby is usually less than 90% of other babies of the same gestational age, which is determined through ultrasound. There are two main types of intrauterine growth restriction: Symmetric or Primary Growth Restriction and Asymmetric or Secondary Growth Restriction. Symmetric growth restriction is characterized by the reduction in the size of all internal organs of the baby whereas asymmetric growth restriction is characterized by the baby having a normal sized head and brain but a smaller abdomen. The second type of intrauterine growth restriction is not evident until after the 28th week (the third trimester) of pregnancy. Intrauterine growth restriction can be caused by many factors, such as poor nutrition during pregnancy, smoking, alcohol, chronic health conditions in the mother and placental abnormalities. These factors result in a reduction of oxygen and nutrients to the baby, hindering its growth and development. Induced labor may be required if the gestational weight is more than 34 weeks. However, when the baby is less than 34 weeks, close monitoring of the mother and baby's condition is done.
