Gallstones

Gallstones are hardened deposits of digestive fluid that can form in your gallbladder. The most common type of gallstone is made up of cholesterol. Gallstones range in size from as small as a grain of sand to as large as a golf ball. Symptoms may include pain in the upper right portion of the abdomen, nausea, vomiting, and fever. Treatment options vary depending on the severity of symptoms and can include medications, surgery, or lifestyle changes.
