Obstructive jaundice is a clinical condition characterised by the accumulation of bilirubin in the bloodstream due to a blockage in the biliary tree, often caused by gallstones, tumours, or strictures. This condition is significant as it can lead to liver damage, cholangitis, and pancreatitis if not promptly addressed. A key association is the presence of pale stools and dark urine, indicating impaired bilirubin excretion and altered liver function.
