What condition is characterized by inflammation of a diverticulum in the colon?

Diverticulitis is characterized by the inflammation of diverticula, which are small, bulging pouches that can form in the lining of the colon. When these pouches become inflamed or infected, it leads to diverticulitis. This condition often presents with symptoms such as abdominal pain, fever, and changes in bowel habits.

The presence of diverticula is typically associated with diverticular disease, and diverticulitis arises when there is an obstruction or irritation that causes inflammation. Effective management often includes dietary changes, antibiotics, and, in severe cases, surgery.

The other conditions listed do not pertain to the inflammation of a diverticulum. Appendicitis involves inflammation of the appendix, cholecystitis refers to the inflammation of the gallbladder, and gastritis is an inflammation of the stomach lining. Each of these conditions has distinct causes and symptoms that differ significantly from those of diverticulitis.
