DIVERTICULITIS Essay
HISTORY- EPIDEMIOLOGY: Diverticulitis is an intestinal inflammation occurring as a complication to the disorder of diverticulosis. The global epidemiology is associated with the western culture diet, being far more common in industrialized countries like the United States, Canada, Australia and the United Kingdom, and much less prevalent in Asia and Africa. These two conditions were rare in the 18th century and appear to be linked to the reduction of fiber in flour due to the development of roller mills that replaced grist mills in the late 1800’s. Roller mills were a more efficient method of refining wheat into flour; however this resulted in the destroying or removal of most of the fiber from the grain. This type

BIOLOGICAL MECHANISM: The condition of diverticulosis occurs when small areas of tissue form pouches in the large intestine or colon called diverticulum, or diverticula (plural). Diverticula may occur due to the lack of bulk forming and bacteria producing fiber, resulting in an imbalance of certain intestinal bacteria, increasing internal pressure on the intestinal tissue due to poor stool formation, constipation, or straining to pass stools. In the paper Low-Residue Diet in Diverticular Disease: Putting an End to a Myth it was stated that “fiber is an important energy substrate for the colonic epithelium because of its fermentation by colonic microbes to short-chain fatty acids, which in turn play a role in mucosal growth and colonic blood flow” (Tarleton, DiBaise 2011). Poor tissue health and increased internal pressure may cause the intestinal tissue to herniate causing diverticulum to form. Diverticulitis can occur when material or bacteria becoming trapped inside the diverticulum, and inflammation…
