Cholecystitis - acute
The gallbladder is an organ that sits below the liver. It stores bile, which your body uses to digest fats in the small intestine.
Acute cholecystitis occurs when bile becomes trapped in the gallbladder. This often happens because a gallstone blocks the cystic duct, the tube through which bile travels into and out of the gallbladder. When a stone blocks this duct, bile builds up, causing irritation and pressure in the gallbladder. This can lead to swelling and infection.

If you are very ill, a tube may be placed through your belly into your gallbladder to drain it. Once you feel better, you may have surgery.
