Neonatal jaundice is one of the common symptoms during the newborn period. It can be divided into physiological and pathological jaundice. Physiological jaundice typically appears in full-term infants two to three days after birth and peaks around the fourth to fifth day. It usually subsides around ten days and generally doesn't last more than two weeks. Physiological neonatal jaundice typically doesn't require intervention. If it is pathological jaundice, where the jaundice progresses quickly and is severe, it is important to consider whether hospital treatment is necessary. The quickest and most effective treatment for severe jaundice is phototherapy with blue light to reduce the bilirubin levels. Additionally, if there are pathological causes, such as infection or hemolysis, treatment should target these underlying causes. Even though phototherapy can reduce bilirubin levels, jaundice may rebound if the underlying issues are not promptly controlled. Therefore, treatment of pathological jaundice should focus on addressing the causes and symptomatic phototherapy.
