What is intrauterine growth restriction (IUGR)?
Intrauterine growth restriction (IUGR) is a term used to describe a condition in which the fetus is smaller than expected for the number of weeks of pregnancy. Another term for IUGR is fetal growth restriction. Newborn babies with IUGR are often described as small for gestational age (SGA). A fetus with IUGR often has an estimated fetal weight less than the 10th percentile. This means that the fetus weighs less than 90 percent of all other fetuses of the same gestational age. A fetus with IUGR also may be born at term (after 37 weeks of pregnancy) or prematurely (before 37 weeks). Newborn babies with IUGR often appear thin, pale, and have loose, dry skin. The umbilical cord is often thin and dull-looking rather than shiny and fat. Babies with IUGR sometimes have a wide-eyed look. Some babies do not have this malnourished appearance but are small all-over.
