Small babies - Low Birth Weight (LBW) or (SGA)
Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. Low birth weight (LBW), is sometimes used to define a baby that weighs less than 5 lb 8 oz (2500 g) regardless of gestational age. One third of babies born with a low birth weight are also small for gestational age.
Other definitions include Very Low Birth Weight (VLBW) which is less than 3 lb 5 oz (1500 g), and Extremely Low Birth Weight (ELBW) which is less than 2 lb 3 oz (1000 g).
About 10 percent of fetuses are low birth weight. A health care provider may suspect fetal growth restriction if the mother's uterus measurement (fundal height) is lower than expected. This can be confirmed with a series of ultrasounds that will monitor how quickly the fetus is growing.
The main causes for Low Birth Weight:
The two main causes of LBW are early delivery, also known as preterm birth, and poor fetal growth. About 70% of all LBW babies are born preterm - before 37 completed weeks of pregnancy. The remaining 30% of low birth weight babies are born at full term, but did not grow properly in the womb.
