What is LGA weight?
At a gestational age of 40 weeks, boys who weigh more than about 9 pounds 4 ounces (4.2 kilograms) are large for gestational age (LGA). Girls who weigh more than about 9 pounds 1 ounce (4.1 kilograms) are LGA. Doctors use published growth charts or computer apps to evaluate babies at other gestational ages.
What is the difference between LGA and macrosomia?
LGA refers to neonatal birth weight larger than the 90th percentile for a given gestational age. In contrast to LGA, fetal macrosomia is defined as an absolute birth weight above a specified threshold regardless of gestational age.
How do you determine LGA?
How is LGA diagnosed?
- Ultrasound. This test uses sound waves to create a picture of your baby and the inside of your body. It is a more accurate method of estimating the size of your baby, but it’s still not exact.
- Weight gain during pregnancy. This can also affect your baby’s size.
What is caput formation?

Babies may be called large for gestational age if they weigh more than 9 in 10 babies (90th percentile) of the same gestational age. This is based on U.S. statistics from 1991.
What is an LGA infant?
Infants who are born large for gestational age (LGA), especially full-term or post-term infants, are at risk for perinatal morbidity and potentially long-term metabolic complications. The pathogenesis, epidemiology, risk factors, complications, and management of infants born LGA will be reviewed here. DEFINITION.
What is a Macrosomic baby?
The term “fetal macrosomia” is used to describe a newborn who’s much larger than average.

What is caput cephalohematoma?
Caput succedaneum is similar to cephalohematoma as both involve unusual bumps or swelling on the newborn’s head. However, the main difference is that lumps caused by bleeding under the scalp is cephalohematoma, whereas lumps caused by scalp swelling due to pressure is known as caput succedaneum.
