Analysis of the causes of yellowing of the eyes

Yellowing of the eyes, medically known as jaundice, is mainly caused by abnormal bilirubin metabolism in the body. Bilirubin is a product of the normal breakdown and destruction of red blood cells, and the liver normally processes bilirubin and excretes it from the body. When this process is blocked, bilirubin builds up in the body, causing the sclera of the eye to turn yellow.

One of the common causes is liver disease such as hepatitis, cirrhosis. When hepatocytes are damaged, they are unable to uptake, bind, and excrete bilirubin normally, resulting in an increase in blood bilirubin levels, causing jaundice. Diseases of the biliary tract system should not be ignored, gallstones, cholangitis, etc., causing bile duct blockage, bilirubin reflux into the bloodstream, which will also make the eyes yellow.

In addition, some blood disorders, such as hemolytic anemia, in which red blood cells are destroyed in large quantities, produce too much bilirubin, which is beyond the liver's ability to handle, and yellow eyes can also occur. Long-term bad lifestyle habits, such as excessive alcohol consumption and staying up late, may affect liver function and indirectly lead to yellowing of the eyes. If you find that your eyes are yellow, you should seek medical attention in time and identify the cause through detailed examination, so that you can take targeted treatment measures to maintain eye and general health.
