The treatment for diverticulitis depends on the severity of the attack. If symptoms are mild, the patient requires antibiotics and a pain reliever and should be on a liquid diet for a few days. More severe episodes may require intravenous antibiotics and further treatment, according to Mayo Clinic.
Diverticula form the lining of the digestive system and become inflamed in diverticulitis, according to Mayo Clinic. Surgery may be recommended if the patient has had numerous episodes of diverticulitis or if the patient is suffering from a serious complication of the disease. Some people have suggested that use of probiotic supplements may prevent diverticulitis flare ups, but there is insufficient evidence to suppoert this treatment.
