What is a Small-for-Gestational-Age (SGA) Infant?

A so-called “term infant with low birth weight” refers to a baby who is born at term—i.e., between 37 and 42 weeks of gestation—but whose birth weight is relatively low, typically under five pounds (approximately 2.3 kg). This condition often suggests suboptimal intrauterine growth, potentially resulting in incomplete development of various organ systems, particularly the gastrointestinal tract and the brain.
