Question
If a newborn has jaundice but only the limbs are not yellow, is this normal?
Answer
Jaundice is a common condition in newborns, primarily caused by abnormal bilirubin metabolism leading to elevated bilirubin levels in the blood, which then causes yellowing of the skin, mucous membranes, and sclera. This condition can be classified into two main types: physiological and pathological. Mild jaundice usually affects only the face and neck, or may extend to the trunk. Jaundice of the sclera may fade after 2-3 days, and the skin color may return to normal after 5-6 days. In severe cases, jaundice may first spread throughout the body and then affect the head. If a newborn’s limbs do not show yellow, parents are advised to communicate with their doctor in detail to determine the nature of the jaundice and the treatment plan.
