the normal population) Ear, nose and throat doctor - to diagnose enlarged adenoids or tonsils (not necessarily more common in those SGA than the normal population) For intrauterine growth restriction (during pregnancy), possible treatments include the early induction of labor, though this is only done if the condition has been diagnosed and seen as a risk to the health of the fetus. Terminology By definition, at least 10% of all newborns will be labeled SGA. Not all newborns that are SGA are pathologically growth restricted and, in fact, may be constitutionally small. However, the designation has prognostic importance because it predicts susceptibility to hypoglycemia, hypothermia, and polycythemia. If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined potential size. This functional definition seeks to identify a population of fetuses at risk for modifiable but otherwise poor outcomes. This definition intentionally excludes fetuses that are small for gestational age (SGA) but are not pathologically small. Infants born SGA with severe short stature (or severe SGA) are defined as having a length less than 2.5 standard deviation scores below the mean. A related term is low birth weight, defined as an infant with a birth weight (that is, mass at the time of birth) of less than 2500 g (5 lb 8 oz), regardless of gestational age at the time of birth. Other related terms include "very low birth weight", which is less than 1500 g, and "extremely low birth weight", which is less than 1000 g. Normal Weight at term delivery is 2500 g - 4200 g. SGA is not a synonym of low birth weight, very low birth weight, or extremely low birth weight. Example: 35-week gestational age delivery, 2250 g weight is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates - infants weighing less than 2500 g - are small for gestational age. There is an 8.1% incidence of low birth weight in developed countries, and 6–30% in developing countries. Much of this can be attributed to the health of the mother during pregnancy. One third of babies born with a low birth weight are also small for gestational age. Infants that are born
