Jaundice is a condition in which the skin, whites of the eyes, and mucous membranes turn yellow due to a high level of bilirubin, a yellow-orange bile pigment. Bilirubin is a byproduct of old red blood cells, and the liver removes the old blood cells and helps break down bilirubin so that it can be removed by the body through the stool. Jaundice can occur when too much bilirubin builds up in the body, and it can be a symptom of several health problems. Causes of jaundice include infections, liver disease, gallstones, tumors, and certain medications. Symptoms of jaundice include yellow skin and the white part of the eyes, yellow color inside the mouth, dark or brown-colored urine, pale or clay-colored stools, and itching. Jaundice is usually a symptom of liver disease, and it can be caused by viral infections, cirrhosis, heavy drinking, autoimmune disease, and other medical conditions. If you experience jaundice and sudden symptoms such as fever, confusion, and intense abdominal pain, seek medical help immediately.
