Do gallstones cause jaundice?
No, jaundice is not contagious. Jaundice is a result of metabolic interruption, often caused by an obstruction of the bile ducts. Because the bile cannot leave the body naturally (in your faeces), it enters the blood stream and turns you yellow. A common cause of jaundice is gallstones, so jaundice is no more contagious than gallstones!
gallstones block the bile duct, and prevent bilirubin getting to the small intestines. it is very important for bilirubin to get to the small intestine's, so if too much bilirubin build up, it will eventually move in to the blood stream. causing your skin to turn yellow, (especially your eyes) and this is called jaundice.
True jaundice comes from the reddish-yellow bile salt, bilirubin. Unusually high concentrations of this compound in the body cause yellowing, or jaundice. Jaundice is typically diagnostic of liver failure. As such, jaundice itself does not spread by touch. However, if an infectious disease has attacked the liver and thus is the root cause of the jaundice, that infection may be transmissible by touch.
