Introduction
A newborn's birth weight is closely related to genetic factors and intrauterine development. If the fetus has good nutritional status during gestation, the birth weight may be higher. Conversely, conditions such as intrauterine hypoxia or growth restriction may lead to lower birth weight. However, as long as a newborn's weight is between 2,500g and 4,000g, it is considered within the normal range.
The birth weight of a newborn infant is generally considered normal if it falls between 2500g and 4000g. Weights below or above this range are considered pathological conditions.
Birth weight plays an important role in monitoring the growth and development of infants, and is usually closely related to genetic factors and fetal development in the uterus. If the fetus receives good nutrition during gestation, the birth weight tends to be higher. Conversely, conditions such as intrauterine hypoxia or restricted growth during pregnancy may lead to low birth weight. However, as long as the newborn's weight is within the 2500g to 4000g range, it is considered normal. Infants weighing less than 2500g at birth are classified as low birth weight, while those weighing more than 4000g are referred to as macrosomic infants; both conditions are considered pathological.
To ensure normal fetal development, pregnant women should avoid excessive physical strain, maintain adequate sleep, and undergo regular prenatal checkups to prevent adverse influences and detect any abnormalities promptly.
