What is the term for delivery before 37 weeks of gestation?

The term for delivery before 37 weeks of gestation is "preterm birth." This classification is critical in obstetrics because deliveries that occur prior to this gestational age can result in various complications for both the infant and the mother. Preterm infants are more likely to experience health issues related to their underdeveloped organs, particularly the lungs and brain.

In contrast, "full-term delivery" refers to births that occur between 39 and 40 weeks of gestation, which are associated with the best outcomes for the infant. "Post-term birth" describes deliveries that happen after 42 weeks of gestation, which can also carry risks and complications. "Term delivery" typically denotes deliveries that fall within the expected range of 37 to 42 weeks.

Understanding these definitions is crucial for healthcare providers in order to assess risks, manage care appropriately, and prepare for the inevitable challenges that may arise with preterm infants.
