    Gallbladder and gallstones

    Gallstones develop when cholesterol and other substances in the bile form crystals that become hard stones in the gallbladder. The gallbladder is a small sac located just under the liver. Gallstones can form when too much cholesterol is in the bile or when the gallbladder does not empty properly.
