The gallbladder is one of the body’s smallest organs. Located right below the liver, it collects bile, necessary for the digestion of fat, and releases it into the small intestine. Gallstones, caused by the crystallization of excess cholesterol in the bile, block the flow of bile and can lead to infection. When infection occurs, or in more extreme cases when the gallbladder bursts, surgery is necessary. Click here for Dr. Oz's Gallstone Prevention Checklist.
