Polyps in the gallbladder do not cause elevated bilirubin. Elevated bilirubin is seen mainly in biliary tract obstruction, as well as in hepatitis and hemolytic anemia. Elevated bilirubin is usually indicative of damage to the liver cells. The liver plays a very important role in the metabolism of bilirubin, and if there is an obstacle to this metabolism, it can lead to elevated bilirubin and jaundice. Polyps in the gallbladder grow within the wall of the gallbladder and do not have a significant effect on bile metabolism, so having gallbladder polyps does not cause elevated bilirubin. If a high bilirubin is found in combination with a gallbladder polyp, there is no causal relationship between the two. Elevated bilirubin should be examined further under the guidance of a medical professional to determine the cause of the condition. Gallbladder polyps do not cause high bilirubin.
