Somebody explain to me what diverticula are and how to treat?

Are outpouchings...: I'm assuming you mean colonic diverticulosis--a permanent outpouching of the colon lining. Diverticular complications include: inflammation (diverticulitis), bleeding, fistulas, perforation. Only surgery can remove diverticulosis (by removing the involved segment of colon), but adding more fiber to your diet can help prevent formation of new diverticular pockets. When inflammed, antibiotics help.
