Question

At five days old, the bilirubin level was 11.3 mg/dL, and the chest circumference was 10.5 cm. No medication treatment was received, and the baby was delivered via cesarean section.

Answer

Mild physiological jaundice may appear as a pale yellow color, confined to the face and neck, or it can spread to the entire body. In severe cases, it may last for more than a week, and in some premature infants, it can last up to four weeks. Blue light therapy is recommended for treatment.
