Are all gallstones in the gallbladder, or can they travel to other sites in the body? Where in the body is the gallbladder located?

Gallstones properly only refer to stones in the gallbladder itself or the bile duct but commonly refer to all stones made out of bile. The overwhelming majority of gallstones are found in the gallbladder or the common bile duct however very rarely they can be dislodged and end up in the neck of the pancreas (causing gallstone pancreatitis) or in the small intestine blocking it up (causing gallstone ileus) The Gallbladder is a pear-shaped organ located just under the liver and often stuck to its base
