Bile duct stones can form within the bile ducts themselves or more commonly occur when gall stones form in the gallbladder and migrate to the common bile duct where they get stuck. Stones in the bile duct may not cause symptoms for years. If the stone lodges in the duct and becomes stuck you may experience abdominal pain, fever, jaundice, nausea, vomiting of loss of appetite. Sudden weight loss, high cholesterol, obesity, biliary tract infections, high-fat diets, liver disease, and high estrogen medications all increase your risk for developing both gall and bile duct stones.
