Cholecystitis occurs when your gallbladder becomes inflamed. Gallbladder inflammation can be caused by:

  • Gallstones. The vast majority of cholecystitis cases are the result of gallstones that block the cystic duct — the tube through which bile flows when it leaves the gallbladder — causing bile to build up and resulting in gallbladder inflammation.
  • Tumor. A tumor may prevent bile from draining out of your gallbladder properly, causing bile buildup that can lead to cholecystitis.
  • Bile duct blockage. Kinking or scarring of the bile ducts can cause blockages that lead to cholecystitis.
