| umls-concept:C0008350 | skos:definition | MSH: Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).,CSP: presence or formation of gallstones in the gallbladder.,MEDLINEPLUS: <p>Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.</p><p>Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the <a href='http://www.nlm.nih.gov/medlineplus/bileductdiseases.html'>bile ducts</a>. That is usually a gallstone. Gallstones form when substances in bile harden. Gallstone attacks usually happen after you eat. Signs of a gallstone attack may include nausea, vomiting, or pain in the abdomen, back, or just under the right arm.</p><p>Gallstones are most common among older adults | lld:umls |
