"Preterm" refers to a baby born before 37 weeks of pregnancy have been completed. A full-term pregnancy typically lasts about 40 weeks, so preterm infants are born too early, which can lead to various health challenges. These babies may have underdeveloped organs and require special medical care to help them grow and thrive. The causes of preterm birth can vary and may include factors such as multiple pregnancies, infections, or chronic health conditions in the mother. Healthcare providers monitor preterm infants closely to address any complications and support their development in the early days of life.
