Acute diverticulitis results from inflammation of the diverticula, typically from an infection. As such, the priority treatment is administration of antibiotics to address the root cause of the condition. Gradually increasing fiber in the diet will occur during the recovery stage of the disease. Pain medication for residual pain would be a second management approach after initiation of antibiotic protocol. To promote rest of the intestinal tract, a liquid diet is advisable for an undeterminable time.
