The gallbladder is a small pear-shaped organ situated under the liver. The liver makes about three to five cups of bile every day. Please refer to the figure below.
Bile helps in the digestion of fats and is stored in the gallbladder.
When fatty foods are eaten, the gallbladder squeezes bile out through the bile duct and into the small intestine.
Gallstones are hardened digestive fluid that can form (cholelithiasis) in your gallbladder.
When gallstones move to the common bile duct and get stuck, it can cause pain, yellowish discoloration of the skin (jaundice) and inflammation.
A condition in which a gallstone is lodged in the common bile duct is called choledocholithiases.
When the inflammation develops in the gallbladder, which can occur suddenly (acute) or over a longer period of time (chronic), the condition is called cholecystitis. Please refer to the figure below.
