Large for gestational age
Large for gestational age (LGA)
Large for gestational age (LGA) refers to a fetus or newborn that is larger in size than the average for the gestational age. Pronounced as /lɑːrdʒ fɔːr dʒɛstəˈʃənəl eɪdʒ/.
Etymology
The term is derived from the English words "large", "for", "gestational", and "age". "Gestational" comes from the Latin word "gestare" which means "to carry or to bear", and "age" comes from the Old French "aage".
Definition
A fetus or newborn is considered LGA if its weight is above the 90th percentile for its gestational age. This means that the baby is heavier than 90% of all other babies of the same gestational age.
Causes
LGA can be caused by a variety of factors, including genetics, diabetes in the mother, and certain syndromes. It is also more common in male babies and in babies of mothers who are overweight or obese.
Complications
Babies who are LGA are at a higher risk of certain complications, including birth injuries, hypoglycemia, and respiratory distress syndrome. They may also have a higher risk of being overweight or obese in childhood and adulthood.
