Large for gestational age babies
Disease Information
Overview
Large for gestational age (LGA) is a term used to describe babies who have birthweights greater than the 90th percentile for their gestational age, meaning that they weigh more than 90 percent of all babies of the same age.
- The average baby weighs about 7 pounds at birth.
- About 10 percent of all babies weigh more than 4,000 grams (8 pounds, 13 ounces).
- Rarely do babies weigh more than 10 pounds.
Although most LGA babies are born at term (37 to 41 weeks of pregnancy), a few premature babies may be LGA.
