Gallstones can cause sudden episodes of severe tummy pain. But many people with gallstones have no symptoms.

Gallstones are thought to be caused by too much cholesterol in your gallbladder. Women and people who are overweight or over 40 are most at risk.

Gallstones do not always need to be treated. If they're causing problems, you may need surgery to remove your gallbladder.

Gallstones are small stones that form in the gallbladder, a small organ found near the liver.
