What are features of obstructive jaundice?

Obstructive jaundice is characterized by a blockage in the bile duct system, which prevents bile from reaching the intestine. As a result, bile components, particularly bilirubin, accumulate in the bloodstream, leading to the classic triad of symptoms.

Pale stools occur because bile, which gives stool its typical brown color, is unable to enter the intestine due to the obstruction. The lack of bile in the gut results in stools that are lighter in color. Dark urine is another feature because the excess bilirubin in the bloodstream is excreted by the kidneys, leading to urine that appears more concentrated and darker than normal. Finally, jaundice itself manifests as a yellowing of the skin and sclera due to the elevated levels of bilirubin in the blood.

In summary, the combination of pale stools, dark urine, and jaundice is a key indicator of obstructive jaundice, making this option a clear reflection of the condition's defining characteristics.
