Yes, gall stones can form from the liver. Bile is a digestive fluid. Bile ducts carry the bile, a yellow-green fluid produced by the liver and stores it in the gallbladder. During eating, the gallbladder contracts and empties bile into the small intestine, called the duodenum. Bile has a central role in helping the body digest fat. It acts as a detergent, breaking up the fat from food into very small droplets, so that it can be absorbed.
However, this bile that the liver produces can harden and eventually form a stone. These then form in the gallbladder. Gallstones my look like small stones or just gravel, being as small as sand, or as large as a pebble. They may take many years to form. Ways of avoiding this situation normally include healthy eating, vegetables rather than high sugar and carbohydrate intake.
