No known foods need to be avoided with diverticulitis, according to Mayo Clinic. Doctors once told individuals with this condition to avoid seeds, nuts and popcorn due to a fear these foods might lodge in the diverticula, but evidence as of 2015 suggests otherwise.
When individuals suffer from diverticulitis, the initial treatment begins with a liquid diet and oral antibiotics to allow the intestines to heal, according to The Merck Manual Home Edition. After a few days, the person switches to a low-fiber, soft diet. At the end of a month, most switch to a high-fiber diet to help move contents through the bowel and reduce pressure. Diverticulitis sufferers typically don't require hospitalization or surgery. If complications occur, individuals may require hospital treatment, including intravenous antibiotics and fluids and taking no food by mouth until the infection heals. In approximately 20 percent of diverticulitis cases, the person requires surgery.
Diverticula are small bulges in the intestines, reports Mayo Clinic. These bulges become more common as a person passes the age of 40. Smoking, obesity and a lack of exercise increase the chances of developing diverticula. People who take certain medications, including over-the-counter pain relievers, have a higher chance of developing diverticula. In most people, diverticula don't cause problems, but if they become inflamed, the person develops diverticulitis.
