Which of the following is NOT a potential cause of jaundice?

• A. Hepatitis A
• B. Cirrhosis
• C. Hepatitis C
• D. Duodenal ulcers

Answer: (D)

Jaundice is characterized by the yellowing of the skin and sclera due to elevated bilirubin levels in the blood. It can be caused by various factors that affect bilirubin metabolism, including liver diseases, bile duct obstructions, and hemolysis.

Hepatitis A, hepatitis C, and cirrhosis all impact liver function, which is central to bilirubin processing. Hepatitis A and C are viral infections that can lead to liver inflammation and consequently impair bilirubin conjugation and excretion. Cirrhosis, which often results from chronic liver disease, significantly disrupts liver function and can lead to jaundice due to liver damage and reduced bilirubin clearance.

In contrast, duodenal ulcers are gastrointestinal conditions that primarily affect the digestive tract, specifically the duodenum. They are not directly related to liver function or bilirubin metabolism. While complications from duodenal ulcers can lead to issues like bleeding, they do not contribute to the jaundice mechanism, making this option the correct choice as a non-cause of jaundice.
