The gallbladder is a hollow organ that stores bile, a fluid produced by the liver which contains a number of substances including wastes produced by the liver. It sits under the liver and empties bile out into the small intestine through the common bile duct. The gallbladder has a neck and its own duct, the cystic duct, which connects it to the common bile duct. Most of us know conditions like gallstones and gallbladder inflammation (cholecystitis) but there are also other types of gallbladder diseases which are less common. Gallbladder torsion is one of these uncommon conditions. It is mainly seen in elderly women although it can occur in younger adults and children. Without prompt treatment, gallbladder torsion can lead to death.
