Which condition involves inflammation or infection of one or more balloon-like sacs in the body?

The condition characterized by inflammation or infection of one or more balloon-like sacs in the body is diverticulitis. This condition specifically affects diverticula, which are small, bulging pouches that can form in the lining of the digestive system, primarily in the colon. When these diverticula become inflamed or infected, it leads to diverticulitis, which can cause symptoms such as abdominal pain, fever, and changes in bowel habits.

Understanding the nature of diverticulitis is essential, especially in a medical context, where recognizing the signs and symptoms can inform appropriate treatment. In contrast, appendicitis involves inflammation of the appendix, located at the junction of the small intestine and the large intestine. Cholecystitis is the inflammation of the gallbladder, usually due to a blockage by gallstones. Pancreatitis refers to inflammation of the pancreas, and while it is a serious condition, it does not involve balloon-like sacs similar to diverticula.
