Preterm delivery, also known as premature delivery, refers to the birth of a baby before the 37th week of pregnancy. Babies born before this time are considered to be preterm and may face several health complications due to their underdeveloped organs and systems. Preterm delivery can occur spontaneously or be medically induced due to medical complications, such as preeclampsia, placenta previa, or fetal distress. Certain factors, such as a previous preterm delivery, multiple pregnancies, and smoking, increase the risk of preterm delivery. Preterm babies may experience respiratory distress syndrome, which can make it difficult for them to breathe and require respiratory support. They may also have difficulty maintaining their body temperature, feeding, and fighting infections. Medical interventions, such as corticosteroids and antibiotics, can be used to reduce the risk of complications in preterm babies.
