A diverticulitis diet is something your doctor might recommend as part of a short-term treatment plan for acute diverticulitis.

Diverticula are small, bulging pouches that can form in the lining of the digestive system. They're found most often in the lower part of the large intestine (colon). This condition is called diverticulosis.

In some cases, one or more of the pouches become inflamed or infected. This is known as diverticulitis.

Mild cases of diverticulitis are usually treated with antibiotics and a low-fiber diet, or treatment may start with a period of rest where you eat nothing by mouth, then start with clear liquids and then move to a low-fiber diet until your condition improves. More-severe cases typically require hospitalization.
