Gallstones are pieces of stone-like material that form in the gallbladder. The gallbladder is located near the liver and stomach. The majority of gallstones are made up of cholesterol. The rest are made up of bilirubin. Bilirubin is a breakdown pigment of the blood product hemoglobin.
Biliary colic is the pain caused by a gallstone stuck in the bile duct (a tube that carries bile to the small intestine). Sometimes, a stone caught in the bile duct causes cholecystitis (inflammation of the gallbladder). Cholangitis is inflammation of the bile duct caused by a gallstone or a bacterial infection.
