The other thought is, and this is not mutually exclusive, that there's damage to the blood vessels at the neck of that sack, and some kind of reduction in the blood flow then leads to bacterial proliferation. In respect to diverticulitis and what causes the actual inflammation, we're not quite sure, but there are two theories: One is that of damage, perhaps due to hard stool or food residue at the neck of the diverticulum, and maybe a micro-perforation (small tears) that over time, collect bacteria.

We're not sure why, but we think that a diet low in fibre somehow alters the colonic motility creating increased pressure within parts of the bowel, such as the left side of the bowel known as the sigmoid colon. Particularly in the Western world, we are seeing an increasing proportion of younger people with diverticulosis. In this article, Dr Lisa Das, a leading consultant gastroenterologist practicing in London, explains which diet you should follow to both help treat and prevent diverticulitis flare-ups.
