Nature and causes of infant jaundice Infant jaundice refers to jaundice caused by excessive bilirubin in the blood of newborns within 3-5 days after birth. It usually heals on its own within 10 days. Jaundice will cause the baby\’s skin and the whites of the eyes to turn yellow. Breastfed babies are more likely to develop infantile jaundice. Treatment methods 1. Drug treatment: When supplementing vitamin K and ruling out a history of hemolytic diseases, drug treatment can be taken, such as indole blue, photosensitizers, etc. 2. Sunbathing therapy: The baby can be exposed to the sun for about 10-15 minutes every day. Since bilirubin is decomposed under ultraviolet rays, exposure to the sun can accelerate the decomposition of bilirubin.
