Blue light for jaundice varies from hospital to hospital and from place to place, and generally costs around 1,000 yuan. The reason for jaundice is that the fetus needs a lot of red blood cells to take in oxygen when it is in the mother’s body. When the fetus is delivered from the mother’s body, the extra red blood cells will be destroyed, producing a lot of bilirubin that exceeds the uptake capacity of the liver cells. You can take probiotics and gardenia yellow to promote the discharge of bilirubin, and in severe cases, you need to take blue light.
