The gallbladder is a small pouch, pear-shaped organ that sits under the liver in the upper abdomen. It stores bile produced by the liver. When food is being broken down in the stomach and intestines, bile is released from the gallbladder through a tube called the common bile duct, which connects the gallbladder and liver to the first part of the small intestine.
Cholecystitis is when the gallbladder is inflamed due to a gallstone in the gallbladder. It causes severe pain and fever and can require surgery if inflammation reoccurs.
Gallbladder cancer is a rare disease in which malignant cells are found in the tissues of the gallbladder. Its usually difficult to diagnose, symptoms resemble gallstones.
When substances in bile become crystallized in the gallbladder, gallstones are formed. The gallstones can be as small as a grain of sand or as large as a golf ball. They can be hard or soft, smooth or jagged. Gallstones are very common and harmless, but are painful.
Gallstone pancreatitis is when the gallstone blocks the ducts that drain the pancreas, causing inflammation.
