The clinical term for yellowing of the eyes and skin is jaundice, which is a yellowing of the skin and sclera caused by excessive bilirubin in the blood. Commonly, the causes of skin and sclera yellowing are obstructive jaundice, hemolytic jaundice, and hepatocellular jaundice. Obstructive jaundice is mainly caused by stones or tumors in the biliary system and requires a CT or MRI to confirm the diagnosis. Hepatocellular jaundice is mainly due to viral hepatitis, while hemolytic jaundice is mainly due to hemolysis of red blood cells in the blood, resulting in an increase in bilirubin.
