When a newborn weighs less than expected for their gestational age, they are considered small for gestational age (SGA). Newborns who weigh between 500-749 grams fall under the category of extremely low birth weight infants (ELBW).
ELBW infants are at a higher risk for health problems and complications than babies born at a normal weight. These complications may include respiratory distress syndrome, apnea, anemia, and infections. ELBW infants may also have difficulty maintaining their body temperature, feeding, and gaining weight.
It is important to note that not all SGA infants are ELBW infants, and not all ELBW infants are SGA. Some infants may be born prematurely and weigh less than expected for their gestational age, while others may experience growth restriction in the womb and be born at a lower weight.
The causes of SGA and ELBW can be numerous and complex. Some factors may include poor maternal nutrition, smoking during pregnancy, chronic health conditions, and fetal abnormalities. Early detection and treatment of these factors may help improve outcomes for ELBW infants.
Overall, caring for an ELBW infant can be a challenging and complex process that requires a team of dedicated healthcare professionals. While the outcomes for ELBW infants can vary, early detection, specialized care, and close monitoring can help improve their chances of a healthy future.
