A gallstone usually forms if your gallbladder or bile ducts are blocked. Gallstones may vary in size. It can be as small as a grain of sand or as big as a golf ball. This can cause pain and lead to harmful effects to the body.

How is gallstones diagnosed?

To determine a proper diagnosis, your doctor may perform the following tests:

  • Medical history and physical exam.

How is gallstones treated?

Gallstones that do not cause symptoms may not need treatment but need close monitoring. If symptoms do appear, treatment options may include the following:

  • Surgery. This may be recommended when gallstones keep reoccurring. When your gallbladder is removed, bile will flow directly from your liver to the small intestine.
  • Drug therapy. There are medications that can dissolve your gallstones but can take a long period time. This is usually the best treatment when surgery is not an option.
