Gallstones are little pebble-like substances that form in the gallbladder, a small organ located under the liver that helps with digestion. These stones develop because cholesterol and pigments in bile sometimes form hard particles. You may have a gallstone and not know it. When symptoms do occur, you may have stomach and back pain, feel nauseous, and may vomit. If you have symptoms of gallstones, it is important to tell your doctor to prevent serious problems from developing.
