How long does it take for jaundice caused by ABO hemolysis to resolve?

The resolution time of ABO hemolytic jaundice varies depending on individual differences and the severity of the condition. Generally, ABO hemolytic jaundice appears within a few days after birth and lasts for about half a month; in most cases, it resolves within 20 days. For infants with more severe cases, the jaundice may persist longer, even for more than one week, especially in preterm infants, where it may last up to four weeks. During the resolution process, the infant's skin and sclera gradually return to normal color, and appetite and mental status also improve. It should be noted that the resolution time of ABO hemolytic jaundice is influenced by multiple factors, including treatment methods and individual differences among infants. Therefore, the exact resolution time should be determined based on each infant's specific condition. If there are any concerns, timely consultation with a physician and appropriate medical treatment are recommended.
