Low Birth Weight (LBW) refers to infants who are born weighing less than 2,500 grams (5 pounds, 8 ounces). It is a significant indicator of newborn health, often associated with various neonatal disorders and long-term health complications. LBW can be categorized into two primary types: preterm birth (born before 37 weeks of gestation) and small for gestational age (SGA).
