Full Form of SGA
What is SGA?
SGA stands for Small for Gestational Age, a widely recognised medical classification used to describe newborns whose birth weight falls below the 10th percentile for their gestational age. In India, this term is routinely used by obstetricians, pediatricians, and neonatologists to identify babies who have not achieved their expected growth potential inside the womb, often because of maternal health issues, placental insufficiency, or fetal factors. The classification plays a critical role in neonatal assessment, helping doctors decide on extra postnatal care, early breastfeeding support, and monitoring for complications such as hypoglycemia, hypothermia, polycythemia, and long-term developmental delays. SGA is different from prematurity, as it specifically refers to growth restriction and applies whether the baby is born at term or earlier. Indian hospitals commonly refer to WHO and Intergrowth-21st standards to plot birth weight against gestational age. For medical aspirants, SGA is a high-yield topic that appears frequently in NEET PG, INI-CET, FMGE, and nursing entrance examinations across obstetrics, pediatrics, and community medicine sections.
