What causes jaundice?

Jaundice can be caused by a problem in any of the three phases in bilirubin production.

Before the production of bilirubin, you may have what's called unconjugated jaundice due to increased levels of bilirubin caused by:

• Reabsorption of a large hematoma (a collection of clotted or partially clotted blood under the skin).
• Hemolytic anemias (blood cells are destroyed and removed from the bloodstream before their normal lifespan is over).

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.
• Medicines, including acetaminophen toxicity, penicillins, oral contraceptives, chlorpromazine (Thorazine®) and estrogenic or anabolic steroids.

After bilirubin is produced, jaundice may be caused by obstruction (blockage) of the bile ducts from:

• Gallstones.
• Inflammation (swelling) of the gallbladder.
• Gallbladder cancer.
• Pancreatic tumor.
