The gallbladder concentrates and stores bile as a pear-shaped sac which it can release to help digestion after a fatty meal.
A contraindication is a condition in which a particular treatment, drug or procedure is rendered unadvisable because of the risks of side effects. A contraindication can either be absolute or relative. An absolute contraindication is one in which there is no option but to completely avoid a given procedure; for example penicillin is not administered to those with a hypersensitivity to the drug. A relative contraindication is one that is inadvisable under normal circumstances but is not completely ruled out; for example pregnant women are advised to avoid x-rays but sometimes x-rays become necessary to detect conditions such as tuberculosis or a broken bone.
