The gallbladder is a little organ that is situated under the liver on the right side of your belly, close to your ribs. It is mostly a storage organ that aids in fat digestion and works to concentrate bile so that it has a greater impact on fat cells. The liver produces bile, which is transported into the gallbladder and stored there by bile ducts. When fat-containing food enters the digestive tract, hormones are stimulated. These hormones stimulate the gallbladder to contract, and this gallbladder contraction enables the gallbladder to discharge bile into the small intestine, facilitating fat absorption. The development of gallstones is the most frequent cause of gallbladder removal. As individuals become older, gallstones are more common, however not everyone experiences symptoms. Gallstones can prevent bile from leaving the gallbladder, or they can even infect the gallbladder itself, causing discomfort after eating fatty foods, which is one of the symptoms of gallstone disease. In humans, gallbladder removal is often well tolerated because it just serves to store bile and does not necessarily affect the operation of other vital organs. When the gallbladder is removed in such a situation, bile is released into the small intestine straight from the liver.
