Neonatal jaundice is one of the common symptoms in newborns. It can be a symptom of the normal developmental process in newborns, or it can be a manifestation of certain diseases. Generally, jaundice is divided into physiological jaundice and pathological jaundice. Physiological jaundice usually does not appear too early, does not progress too quickly, and is not too severe. The jaundice slowly subsides after peaking, and generally lasts no more than two weeks. If it is pathological jaundice, the degree of jaundice is relatively severe, and its main manifestation is that the skin turns noticeably yellow, possibly spreading to the limbs, yellowing of the whole body, and obvious yellowing of the palms and soles. Additionally, there may be other uncomfortable symptoms, such as fever or drowsiness, refusal to nurse, vomiting, obvious abdominal distension, or a significant increase in stool, etc. In such cases, pathological jaundice should be considered, and medical attention should be sought promptly.
