Neonatal jaundice is one of the common symptoms in newborns, especially in early newborns. Neonatal jaundice can be a normal physiological phenomenon, but it can also be a manifestation of certain diseases. Generally, if it is physiological jaundice in full-term babies, it usually resolves within about ten days, and generally lasts no longer than two weeks. In premature babies, it tends to last longer, generally not exceeding four weeks. However, if the jaundice persists for a long time, progresses quickly, and is severe, it may be pathological jaundice. Pathological jaundice might be associated with other discomforts, and in such cases, it is necessary to identify possible pathological factors and treat them accordingly to gradually control and reduce the jaundice. Therefore, if the jaundice persists for a long time, it is advisable to go to the hospital for some relevant tests to determine its nature, and if it is pathological jaundice, timely intervention and treatment are recommended.
