What is Acute Cholecystitis?

Acute cholecystitis is inflammation of the gallbladder, most commonly caused by a gallstone blocking the tube that allows bile to drain from the gallbladder. It typically causes sudden, severe pain in the upper right abdomen, which can spread to the back or shoulder, often alongside fever and nausea.

It usually requires hospital treatment, including antibiotics and, in many cases, surgical removal of the gallbladder, either during the same admission or scheduled shortly afterward once the inflammation has settled.
