Glossary -   Gallstones

 

 

Gallstones are hardened balls of digestive fluid that form in the gallbladder. The gallbladder is the organ that releases digestive fluid during digestion. Gallstones can be as small as a grain of sand or as large as a golf ball. They cause no symptoms in some people and many complications in others. Signs of gallstones include yellowing of the eyes and pain in the upper right abdomen.
