Large for gestational age (LGA) is how health professionals describe newborns who weighing more than the usual amount for the number of weeks of pregnancy.
1 The term large for gestational age, or LGA, means a fetus or infant is larger or more developed than normal for the baby's gestational age. 2  Gestational age is a measure of the growth and development of the fetus in the uterus and the infant after birth. 1 Gestational age is a measure of the growth and development of the fetus in the uterus and the infant after birth. 2  A fetus or infant larger than expected for the age and gender, or with a birth weight above the 90th percentile, is referred to as LGA. LGA babies 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 gestational age. The average baby weighs about 7 pounds at birth. About 9 percent of all babies weigh more than 4,000 grams (8 pounds, 13 ounces). Rarely do babies weigh over 10 pounds. Although most LGA babies are born at term (37 to 41 weeks of pregnancy), a few premature babies may be LGA. Some babies are large because their parents are large; genetics does play a part Increased risk of birth injuries: Newborns who are large for gestational age are at increased risk of birth injuries such as stretching of the nerves in the shoulder (brachial plexus injuries) and collarbone (clavicle) fractures. A newborn, whether delivered preterm, term, or postterm, whose weight is above that of 90% of newborns of the same gestational age at birth (above the 90th percentile) is considered large for gestational age. Etiology. Other than genetically determined size, maternal diabetes mellitus is the major cause of large-for-gestational-age (LGA) infants. The macrosomia results from the anabolic effects of high fetal insulin levels produced in response to excessive maternal blood glucose during gestation. The Fenton growth charts provide a more precise assessment of growth vs gestational age (see Figure: Fenton Growth Chart for Preterm Boys and see Figure: Fenton Growth Chart for Preterm Girls).
