Gallstones: The most common cause of cholecystitis, gallstones block the normal flow of bile from the gallbladder, leading to its inflammation.
Bile Duct Obstruction: Any blockage in the bile ducts, such as a tumor or strictures, can cause bile to back up and lead to inflammation of the gallbladder.
Infections: Bacterial infections, particularly those from E. coli, can lead to cholecystitis, especially in people who have gallstones.
Trauma: Injury to the abdomen or gallbladder can cause inflammation or infection, leading to cholecystitis.
AIDS or HIV: Certain infections associated with AIDS, such as cytomegalovirus (CMV), can cause cholecystitis.
Diabetes: Individuals with diabetes may be more prone to infections, which can increase the risk of cholecystitis.
Viral Infections: Some viral infections like cytomegalovirus (CMV) can also lead to gallbladder inflammation.
Poor Diet: A high-fat diet can increase the risk of gallstones, leading to an increased likelihood of cholecystitis.
Chronic Illnesses: Conditions like Crohn's disease, cirrhosis, or sickle cell anemia may also contribute to the development of cholecystitis.
