What does it mean if the white part of the eye turns yellow?

Yellowing of the white part of the eye, medically known as scleral icterus, is usually a sign of jaundice caused by elevated bilirubin levels. This may be due to liver diseases such as hepatitis or cirrhosis, or biliary tract problems such as gallstones or bile duct obstruction. In addition, certain blood disorders, genetic conditions (such as Gilbert's syndrome), or excessive alcohol consumption can also lead to this condition. If yellowing of the whites of the eyes occurs, prompt medical attention is recommended for a comprehensive evaluation, including blood tests, liver function tests, and imaging studies, to determine the underlying cause. At the same time, maintaining healthy lifestyle habits, such as drinking adequate water, avoiding alcohol and excessive fatigue, can help protect liver health. Under a doctor's guidance, medication or further treatment interventions may be necessary.
