There is not a cure for diverticulitis, although treating mild symptoms at home often has a success rate of 70 to 100 percent. In severe cases of diverticulitis, intravenous antibiotics and drainage tubes may be necessary. Life-threatening infections requiring surgery may occur, according to Mayo Clinic.
Diverticulitis most often occurs when weak areas in the wall of the colon cannot withstand pressure, which causes small pouches to form in the colon wall. These pouches, referred to as diverticula, are fairly common and normally do not cause problems. Diverticulitis occurs when these pouches become inflamed or infected, according to Mayo Clinic.
