Most gallstones do not cause symptoms unless they get caught in the ducts that connect the liver and small intestine, according to WebMD. When this occurs, patients may experience symptoms like abdominal pain, fever, nausea, yellowing skin and eyes, and dark-colored urine or stools.
Gallstones are hard clumps of cholesterol and bile pigments that originate in the gallbladder, a small organ just below the liver, states WebMD. When they get stuck in the ducts connecting the gallbladder to the small intestine, they block the natural flow of bile and cause the fluid to back up into the liver and enter the bloodstream.
