Diverticulitis is a condition that affects the large intestine, or colon. The condition is characterized by small, bulging pouches that form in the lining of the intestine. These pouches are called diverticula, and when they become inflamed or infected, the condition is known as diverticulitis.

Diverticulitis can be a painful condition, and symptoms may include abdominal pain, cramping, bloating, and constipation. In some cases, the inflamed pouches can rupture, causing infection and other complications.

Diverticulitis is most common in older adults, and it is thought to be caused by a combination of factors, including a low-fiber diet and lack of exercise.

Treatment typically involves antibiotics to clear the infection, pain relief, and changes in diet. In severe cases, surgery may be necessary.
