Pigment Gallstones

Pigment gallstones are small, dark-colored stones that form in the gallbladder, primarily made of bilirubin, a pigment from the breakdown of red blood cells. They develop when there's excess bilirubin in the bile, often due to conditions like liver disease or certain blood disorders. These stones are more common in Asian populations and individuals with hemolytic anemia. Unlike cholesterol stones, pigment gallstones are denser and harder. They may cause symptoms such as pain, nausea, or digestive issues if they obstruct bile flow. Treatment can include medication or surgical removal of the gallstones or gallbladder.
