Detailed explanation-1: -Gallstones form when bile stored in the gallbladder hardens into stone-like material. Too much cholesterol, bile salts, or bilirubin (bile pigment) can cause gallstones. When gallstones are present in the gallbladder itself, it is called cholelithiasis.

Detailed explanation-2: -Gallstones are hard, pebble-like pieces of material, usually made of cholesterol or bilirubin, that form in your gallbladder. Gallstones can range in size from a grain of sand to a golf ball.

Detailed explanation-3: -Cholesterol gallstones are made mainly of hardened cholesterol, although they also contain other substances. If the stones contain more than 50% cholesterol, they’re classified as cholesterol gallstones. About three-quarters of all gallstones are cholesterol stones.

Detailed explanation-4: -Cholesterol gallstones are formed mainly due to over secretion of cholesterol by liver cells and hypomotility or impaired emptying of the gallbladder. In pigmented gallstones, conditions with high heme turnover, bilirubin may be present in bile at higher than normal concentrations.
