Neonatal jaundice is one of the most common symptoms during the newborn period. It can be a normal physiological phenomenon occurring in the baby's development process, or it may indicate some diseases. Neonatal jaundice is divided into physiological jaundice and pathological jaundice. Generally, the degree of jaundice in physiological jaundice is not very high, and the general condition is still okay. The baby does not show any special discomfort. However, if it is pathological jaundice, the jaundice usually lasts longer and progresses faster with a more severe degree. There might be other discomforts, such as obvious crying and restlessness, possibly even fever, and other symptoms like sleepiness or refusal to feed. Therefore, if the jaundice is slightly high, the general condition is still manageable, and parents should not worry too much. However, if there are obvious discomforts, it is recommended to visit the hospital promptly because if a newborn baby gets sick and is not treated in time, the condition can progress quickly.
