Gall stones

What are Gallstones?

Gallstones are collections of hard, solid material that form in the gallbladder. Some may be the size of a grain of sand, or they may be crystals that can be seen only with a microscope. Others may be the size of a golf ball. People can develop just one large stone, hundreds of smaller stones, or combinations of both.


  • Gallstones form when cholesterol and other things found in bile make stones.
  • They can also form if the gallbladder does not empty as it should.
