What are Gallstones?
By Dr Ananya Mandal, MD
Gallstones are small stones that form within the gallbladder and are usually made up of cholesterol.
In the majority of people with gallstones, the stones do not cause symptoms or require treatment. However, treatment may be necessary if a gallstone becomes trapped in the gallbladder and starts to cause symptoms and complications. When this happens, a patient is said to have gall bladder disease.
