Premature Baby:A premature baby is one born before completing 37 weeks of pregnancy. Traditionally, prematurity was defined by a birth weight of 2500 grams (approximately 5 1/2 pounds) or less. However, the modern understanding classifies a premature baby as one born prior to 37 weeks of gestation, starting from the first day of the last menstrual cycle.The risks associated with premature birth increase the earlier the baby is born before reaching the 37-week mark. Babies born slightly early might experience minimal or no health issues. However, the earlier a baby is born during fetal development, the more likely life-support measures will be necessary, and the higher the chance of birth defects and mortality.Various methods, such as bed rest and medications, can be utilized to prevent early labor. If early delivery is unavoidable or required for medical reasons, a C-section may be performed to minimize stress on the infant and safeguard its health.In everyday language, a premature baby is often referred to as a preemie.
