জন্ডিস রোগের প্রধান কারণ-

Jaundice is a condition in which the skin, sclera (whites of the eyes) and mucous membranes turn yellow. This yellow color is caused by a high level of bilirubin, a yellow-orange bile pigment. Bile is fluid secreted by the liver. Bilirubin is formed from the breakdown of red blood cells.

During production of bilirubin, jaundice can be caused by:

• Viruses, including Hepatitis A, chronic Hepatitis B and C, and Epstein-Barr virus infection (infectious mononucleosis).
• Alcohol.
• Autoimmune disorders.
• Rare genetic metabolic defects.
