Even though irritable bowel syndrome and diverticulitis are very similar in symptoms they have very different causes and medical treatments. Irritable bowel syndrome or IBS is defined as a functional
gut disorder and is not a disease at all. IBS can be best treated with a diet change by incorporating high fiber into a persons diet. Diverticulitis is when a person who has small pouches in the colon that protrude out through weak spots (diverticulosis) that become inflamed or infected. Several complications can come from this disease, including infection, serious pain, intestinal obstructions and fistulas. A diet high in soluble fiber will help relieve symptoms and prevent flare ups.
