Hello, I'm a healthcare professional with experience in neonatal care. Jaundice is a common condition in newborns, characterized by a yellowing of the skin and eyes due to elevated bilirubin levels. Phototherapy is a common treatment for jaundice, which involves placing the baby under a special blue light that helps break down bilirubin.

The duration a baby needs to be under the light for jaundice treatment can vary significantly based on several factors, including the severity of the jaundice, the baby's age, and their response to the treatment. Typically, phototherapy is started when the bilirubin levels reach a certain threshold, as determined by the healthcare provider.

During the treatment, the baby's bilirubin levels are closely monitored. The light therapy may last anywhere from a few hours to several days. In some cases, if the bilirubin levels are not decreasing as expected, the duration of the therapy may need to be extended. It's important to follow the recommendations of the healthcare provider, as they will have the most accurate information about the baby's condition and the appropriate course of action.

Another bilirubin level will be checked 12�C18 hours later to make sure it hasn't risen again. Babies usually need to be under phototherapy lights for around 48 hours and often longer. Physiological jaundice normally clears by the time your baby is two weeks old.read more >>
