Why might choledocolithiasis cause jaundice?

Choledocolithiasis, the presence of gallstones in the common bile duct, can indeed cause jaundice. Here's why:

1. Obstruction of Bile Flow: Gallstones can block the common bile duct, which is responsible for carrying bile from the liver and gallbladder to the small intestine. This obstruction prevents the normal flow of bile, leading to a buildup of bilirubin in the bloodstream.

2. Bilirubin Accumulation: Bilirubin is a yellow pigment that is produced when red blood cells are broken down. Normally, bilirubin is transported by bile to the small intestine and eventually eliminated from the body through feces. However, when the bile duct is blocked by gallstones, bilirubin cannot be excreted properly and accumulates in the blood.

3. Jaundice: The buildup of bilirubin in the blood causes jaundice, a condition characterized by yellowing of the skin, whites of the eyes (sclerae), and mucous membranes. This yellow discoloration occurs due to the deposition of bilirubin in these tissues.

4. Other Symptoms: In addition to jaundice, choledocolithiasis can also cause other symptoms, including abdominal pain, nausea, vomiting, fever, and chills. These symptoms may occur due to the inflammation and irritation caused by the gallstones blocking the bile duct.

It is important to note that not all cases of choledocolithiasis will result in jaundice. Some individuals may experience mild or no symptoms, while others may develop severe complications, such as cholangitis (inflammation of the bile ducts) or pancreatitis (inflammation of the pancreas).

If you suspect that you may have choledocolithiasis or are experiencing symptoms such as jaundice, abdominal pain, or nausea, it is essential to seek medical attention promptly for proper evaluation and treatment.
