Obstruction of bile ducts
Gallstones, tumors, trauma, cysts, and inflammation can cause blockages or obstructions in the bile ducts. When this is severe, bile and its associated wastes accumulate in the liver, causing jaundice, dark brown urine, and pale-colored stools. The affected person may not have any symptoms initially, but if the condition persists or worsens, it can cause liver and gallbladder damage. If the duct that drains bile from the gallbladder is blocked, it can cause sharp pain to develop suddenly in the upper right part of the abdomen and may lead to fever and gallbladder infection.
