High Fibre Diet and Diverticulosis Colon diverticulosis occurs when pockets or sacks bulge out from the bowel wall. It is known that these diverticulae occur gradually over time and are due to excessive pressure or spasms within the bowel. A high-fibre diet increases the bulk in the stool, which reduces pressure within the colon. By so doing, diverticula formation may be reduced or even stopped.
