Jaundice in children can be divided into physiological jaundice and pathological jaundice. Physiological jaundice can subside on its own and has no obvious effect on children, while pathological jaundice can lead to bilirubin encephalopathy, which may result in hearing impairment, mental retardation and other phenomena. 1. Physiological jaundice: generally, it can subside by itself, and children’s appetite, spirit and weight gain are good without special discomfort, so physiological jaundice will not have sequelae, and there is no need for special treatment. 2. Bilirubin encephalopathy: it is a serious complication of pathologic jaundice. As the blood-brain barrier of children is not fully developed, non-conjugated bilirubin may pass through the blood-brain barrier and enter into the central nervous system, thus causing bilirubin encephalopathy, which will lead to ocular motility disorders, auditory disorders, and even backwardness of intelligence, and sequelae such as convulsive salivation (drooling) and so on. Jaundice in children can lead to the possibility of serious results, so when jaundice is found, it is recommended to go to the hospital in time to find out the cause of the disease and give timely treatment under the guidance of the doctor.
