Diverticulitis is a condition in which small, bulging pouches (diverticula) that can form in the lining of the digestive system become inflamed or infected. These pouches are most commonly found in the lower part of the large intestine (colon). While diverticulosis is the presence of diverticula, diverticulitis occurs when one or more of these pouches become inflamed, leading to symptoms like abdominal pain, fever, and changes in bowel habits.
