Q

What causes jaundice?

A

An increase in circulating bilirubin. This is usually because the hepatobiliary system is unable to process the amount of bilirubin in the blood for pre-hepatic, hepatic or post-hepatic reasons.

Q

What causes pale stool?

A

The normal brown colour of faeces is due to the presence of stercobilin. This pigment arises from bilirubin that enters the gut through bile secretion, so if bilirubin doesn’t make it into the gut then stercobilin concentration will go down and stools will become pale.
