The hazards of neonatal jaundice are: 1, physiological jaundice: no effect on later growth and development; 2, pathological jaundice: acute bilirubin encephalopathy, after treatment, has less impact on its later growth and development. If the period of treatment is missed and nuclear jaundice is formed, it will affect the nervous system and cause abnormalities in brain development and motor development later in life, including hand and foot tremors, permanent damage to dental development and hearing. If permanent nuclear jaundice is formed, a late sequelae period will occur, and the chances of recovery from such manifestations are low, affecting their quality of life.
