What defines a full-term pregnancy in weeks?

A full-term pregnancy is defined as one that lasts from 37 to 42 weeks of gestation. This range is crucial because it marks the optimal time for fetal development, when the baby is typically fully developed and can transition successfully to life outside the womb.

Pregnancies that extend beyond 42 weeks are categorized as post-term, which can pose increased risks for both the mother and the baby, such as the potential for decreased amniotic fluid, increased chances of cesarean delivery, and increased fetal distress. Conversely, pregnancies that are considered preterm, occurring before the 37-week mark, may result in infants who require additional medical care due to being underdeveloped at birth.

Understanding this gestational age range is vital for healthcare providers in managing prenatal care and making informed decisions regarding labor and delivery.
