Introduction to the Causes of Neonatal Jaundice

Neonatal jaundice is caused by abnormal bilirubin metabolism, leading to elevated bilirubin levels in the blood and resulting in yellowing of the skin, mucous membranes, and sclera. It is one of the most common issues in neonates, categorized into physiological and pathological types. Physiological jaundice usually requires no special treatment, while pathological jaundice may necessitate blue light therapy to facilitate bilirubin reduction.

Explore the two types of neonatal jaundice: physiological and pathological, and their causes and treatment methods.

Neonatal jaundice usually appears within 2-3 days after birth and reaches its peak between 4-6 days, then gradually diminishes. For full-term infants, jaundice typically subsides within 2 weeks after birth; for premature infants, it may take up to 3 weeks. The severity of jaundice is generally mild, with the baby’s skin color turning pale yellow, and jaundice usually only affects the face and upper body. During the period of jaundice, the baby remains in good overall condition, with normal body temperature, appetite, and normal color of urine and stool, as well as normal growth and development.

Neonatal physiological jaundice may be caused by abnormal bilirubin metabolism.

Neonatal jaundice may be caused by physiological reasons. Mild jaundice usually subsides within a few days, while severe jaundice may persist for a longer period. It is recommended to use blue light therapy for treatment.
