Gallstones are solid lumps of cholesterol crystals or pigment material that form in the gall bladder. What is the gall bladder and what does it do? The gall bladder is a pouch that sits beneath the liver and stores bile, which is a greenish-yellow fluid produced by the liver. When we eat, the gall bladder releases bile into the small intestine where it helps to digest fats.
