Jaundice is yellow eyes and/or skin. Its usually caused by too many red blood cells retiring, by the liver being overloaded or damaged, or by the inability to move processed bilirubin from the liver through the biliary tract to the gut. It arises for many reasons, including blood incompatibilities, blood diseases, genetic syndromes, hepatitis, cirrhosis, bile duct blockage, other liver diseases, infections, or medications. The term also applies to physiologic jaundice exaggerated by dehydration.
Edited to add: you should make an appointment with your doctor to get this checked out.
