Why does liver disease make you jaundiced?

Bilirubin. The liver is in charge of the body's bilirubin. As the liver gets sick, the levels of bilirubin rise in the blood to abnormal levels. Bilirubin over a certain level causes jaundice.
Backup of Toxins. The liver is the bodies main recycling center. Blood brings toxins & metabolic debris to the liver. Liver tissue processes the material and dumps the waste into bile channels which empty into the intestines. The waste is greenish but turns yellow & brown over time providing color to stool. If the liver is unable to clean the blood, the material backs up & produces the yellow skin color. .
