If it is the mild benign rise known as Gilbert's syndrome there is nothing you can do and no reason to try.
If it is the exaggerated normal jaundice (high bilirubin levels leading to yellow skin) of newborn babies then "light therapy" with UV lights are usually used. In extreme cases exchange transfusion can be done. Glass blocks UV light so the common advice to put the baby in front of a window is not effective. Exposing the baby to direct sunlight and the elements is not safe.
In other situations the underlying cause (usually liver, gall bladder, or blood issues) needs to be addressed.
Bilirubin levels can be measured by blood tests
Bilirubin levels are most often elevated in patients with liver disease or a blockage to bile flow
Simple.... Death.
use to check bilirubin levels
Bilirubin is a pigment that is made by the liver and is found in bile. Certain diseases can cause high levels of bilirubin, such as a gallbladder infection, gallstones, cirrhosis, hepatitis, and pancreatic cancer.
The medical term for bilirubin in the blood is hyperbilirubinemia.
Bilirubin
That sounds a littel high. What are your liver enzyme levels? and are you jaundice?
Newborn jaundice is caused when there are high bilirubin levels in the blood.
Bilirubin is a yellow-brown fluid found in bile, and is the breakdown of the heme in hemoglobin. Normal levels for total bilirubin are usually .3 to 1 mg/dl, or 5 to 17 mmol/L.
Before birth, an infant gets rid of bilirubin through the mother's blood and liver systems. After birth, the baby's liver has to take over processing bilirubin on its own.
jaundice the normal serum bilirubin level is 0.5 to 1.5mg%. jaundice occurs when the bilirubin level exceeds 2mg%. the increased blood level of bilirubin is called hyperbilirubinemia. excess bilirubin from blood diffuses into the tissues, skin and mucous membrane, colouring them yellow. this condition caused by overflow of bilirubin is called jaundice.
