Large for gestational age (LGA) means that a fetus or infant is larger or more developed than normal for the baby's gestational age.
InformationGestational age is a measure of the growth and development of the fetus in the uterus and the infant after birth. LGA refers to a fetus or infant who is larger than expected for the age and gender or with a birth weight above the 90th percentile.
The measurement is based on the estimated gestational age of the fetus or infant, compared with what is considered normal height, weight, head size, and developmental level for a fetus or infant of the same age and gender.
Common causes of a fetus or infant who is large for gestational age are:
A baby that is large for gestational age has a higher risk of birth injury and complications of low blood sugar after delivery.

LGA- large for gestational age SGA- small for gestational age
DefinitionAppropriate for gestational age (AGA) describes a fetus or newborn infant whose size is within the normal range for his or her gestational age.InformationAssigning size is a way to measure and monitor the growth of the infant throughout the pregnancy as well as at the time of birth.The measurement is calculated based on the estimated gestational age (how many weeks the mother was pregnant) in comparison to what is considered normal height, weight, head size, and developmental level for a child of the same gestational age and gender.Graphs are available showing the upper and lower normal limits for different gestational ages from the mid-20s through 42 weeks of gestation.An appropriate for gestational age full-term infant is heavier than 2500 grams (about 5.5 lbs.) and lighter than about 4000 grams (about 8.75 lbs.).For infants weighing less, see: Small for gestational age (SGA)For infants weighing more, see: Large for gestational age (LGA)Knowing the group into which an infant fits is important. An AGA baby tends to have the lowest risk for any problems. AGA babies have lower rates of disease and death than babies that are small or large for their gestational age.
A term used to describe newborns who are below the 10th percentile in height or weight for their estimated gestational age. The gestational age is based upon the date of the mother's last menstrual period
