The underlying etiology is thought to be due to microperforation of diverticula. Smoking and obesity are associated with increased risk of diverticulosis and diverticulitis. Computed tomography (CT) of the abdomen and pelvis confirms the diagnosis in most instances.
Treatment is determined by severity and complexity of diverticulitis. Mild cases can be managed as an outpatient with oral antibiotics, with more severe cases requiring intravenous antibiotics. Complicated diverticulitis may require surgery in some instances.
