Cholecystitis is commonly associated with which condition?

Cholecystitis is an inflammation of the gallbladder, and it is most commonly associated with the presence of gallstones. The condition arises when a gallstone obstructs the cystic duct, leading to bile accumulation and subsequent inflammation of the gallbladder wall. This blockage can result in symptoms such as abdominal pain, fever, and nausea, and may lead to complications if not treated.

Each of the other conditions listed has different pathophysiological mechanisms that do not directly correlate with cholecystitis. For example, diverticulitis involves the inflammation of diverticula in the colon, while pancreatitis involves inflammation of the pancreas, which can be associated with gallstones but is not directly linked to cholecystitis itself. Peptic ulcers primarily affect the stomach or duodenum and are related to acid damage rather than gallbladder issues. Therefore, the strongest and most direct relationship is between cholecystitis and gallstones, making this option the most appropriate choice.
