Neonatal jaundice is one of the common symptoms in neonates, especially in early newborns. It can be a symptom of normal development in newborns, or it can be a manifestation of certain diseases. Jaundice is generally divided into physiological jaundice and pathological jaundice, with the main symptom being the yellowing of the skin and mucous membranes. Typically, jaundice starts from the face and then spreads to the trunk and limbs. If the degree of jaundice is relatively severe, yellowing will appear on the entire body, including the ears. Generally, if the baby is visibly yellow, it is advisable to monitor the jaundice. If the jaundice value is significantly high and confirmed to be high in the blood, it is considered pathological jaundice, and it is recommended to seek timely intervention and treatment.
