Doctor's answer:

In your case, it may be physiological jaundice. Physiological jaundice is mild when it appears light yellow, limited to the face and neck, or may affect the trunk, and the sclera may also turn yellow. It usually subsides within 2 to 3 days and the skin color returns to normal by the 5th to 6th day. In severe cases, jaundice can also start from the head and spread to the feet, affecting the entire body. Vomitus and cerebrospinal fluid may also turn yellow, and the duration can last for more than a week. In some premature infants, it may persist for up to 4 weeks, with the stool still remaining yellow and no bilirubin in the urine. It is recommended to use blue light therapy, which can be effective.
