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

  • Gallstones. Most cholecystitis is the result of hard particles that develop in your gallbladder  (gallstones) from imbalances in the substances in bile, such as cholesterol and bile salts. Gallstones can block the cystic duct — the tube through which bile flows when it leaves the gallbladder — causing bile to build up and resulting in 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.
