Diverticula occur in areas of relative colonic wall weakness passing through the circular muscle layer where blood vessels ( vasa recta) penetrate to supply the mucosa.
These herniations create small pouches lined solely by mucosa. These can occur anywhere in the GI tract. Sigmoid colon has the highest intra luminal pressures and is most commonly affected.
In addition to the changes in colonic wall, alterations in colonic motility have been implicated for the development of diverticular disease.
The cause of diverticuloses is uncertain but but it appears to be associated with a low-fiber diet, constipation, and obesity.
