the gallbladder is a small sac found just under the liver. it stores bile made by the liver. bile helps you digest fats. bile moves from the gallbladder to the small intestine through tubes called the cystic duct and common bile duct. gallstones are made from cholesterol and other things found in the bile. they can be smaller than a grain of sand or as large as a golf ball. most gallstones do not cause problems. but if they block a duct they usually need treatment. webmd medical reference from healthwise this information is not intended to replace the advice of a doctor. healthwise disclaims any liability for the decisions you make based on this information. © 1995-2011 healthwise incorporated. healthwise healthwise for every health decision and the healthwise logo are trademarks of healthwise incorporated.
