Premature birth refers to the delivery of a baby before completing 37 weeks of gestation. This can lead to various complications as the baby may not have developed fully yet. Some synonyms used for premature birth include preterm birth, preemie birth, premature delivery, and premature labor. These terms are often used interchangeably but differ slightly in their implications. Preterm birth emphasizes the timing of birth, while preemie birth suggests a baby born too early and often needing specialized care. Premature delivery or labor refers to the circumstances of when the baby was born. Despite their differences, these synonymous terms all denote a baby born before their due date, needing medical attention to thrive.
