Which condition is the inflammation of the gallbladder, often associated with gallstones?

• A. Cholecystitis
• B. Pancreatitis
• C. Peritonitis
• D. Gastroenteritis

Answer: (A)

Cholecystitis is the inflammation of the gallbladder, typically caused when a gallstone blocks the cystic duct, leading to gallbladder distension and an inflammatory response. This condition is classically associated with gallstones and presents with right upper quadrant pain, fever, and often nausea. The link to gallstones is the hallmark naming here—the gallbladder itself becomes inflamed because its outlet is blocked.

Other ideas refer to different organs: pancreatitis involves the pancreas (and can be related to gallstones but is a separate organ with a distinct pain pattern and tests), peritonitis involves the peritoneum lining the abdomen, and gastroenteritis involves the stomach and intestines with symptoms like vomiting and diarrhea.
