Gallstones are hardened deposits of digestive fluid that can form in your gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, located just beneath your liver. In addition, the gallbladder holds a digestive fluid called bile that’s released into your small intestines.
Gallstones can range in size from as small as a grain of sand to as large as a golf ball. Some people develop just one gallstone, while others develop a lot of them at the same time. Furthermore, people who experience symptoms from their gallstones usually require a surgery for gallbladder removal.
Lastly, gallstones that don’t cause any symptoms usually don’t require treatment.
