Baby Birth Also: LBW

Low birth weight

Abbreviation: LBW

Low birth weight (LBW) describes any baby born weighing less than 2,500 grams, regardless of how many weeks of pregnancy have passed. A baby can be low birth weight because they were born early (preterm) or because they did not grow well in the womb (intrauterine growth restriction). LBW babies are at greater risk of hypothermia, low blood sugar, infection, and feeding difficulties in the newborn period. Longer term, research links low birth weight to a higher risk of certain chronic conditions. Close monitoring, adequate nutrition, and keeping the baby warm are the most important early priorities for parents and care teams.
