Large for gestational age (LGA)

Definition
Information


 Definition  

Large for gestational age (LGA) means that a fetus or infant is larger or more developed than normal for the baby's gestational age.

 Information  

Gestational 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.
