The gallbladder, a small organ located in the abdomen, cannot grow back after it has been surgically removed. According to WebMD, the gallbladder is often removed due to gallstones, and it is possible to live comfortably without a gallbladder.
The gallbladder is located beneath the right side of the liver. Its function is to store bile, which is produced by the liver. During digestion, this bile is excreted from the gallbladder into the small intestine, where it assists with digestion of fats.
Gallstones occur when the bile crystallizes, creating small stones. These stones can block the bile duct, which can cause the gallbladder to become inflamed. If gallstones continue to reoccur, this could lead to a doctor recommending removal. A doctor will usually recommend removal of the gallbladder if it becomes inflamed. The absence of the gallbladder does not cause any serious long-term difficulty.
