The sigmoid colon is usually affected, probably due to its smaller size. Laplace

The DD is much more frequent in older people, with only 2-5% of cases occurring below 40 years. The DD this younger group is more frequent in men with obesity as a major risk factor colo (present in 84-96% of cases). Diverticula is usually located in the sigmoid colon and / or downstream. colo The handling of this subgroup of patients remains controversial. The concept that DD would be more "virulent" in young people is a matter of debate. The natural history really shows a tendency to recurrence of symptoms and an increased adverse change requiring surgery incidence. colo
Insoluble fibers cause the formation of bulkier stool that leads to a
There is no evidence of a relationship between the development of diverticula and smoking, consumption colo of alcohol or caffeine. It is observed, colo however, an increased risk of developing diverticular disease associated with diet rich in fat and red meat. This risk can be reduced by a diet rich in fiber, especially if they are derived from cellulose (fruits and vegetables).
The most typical presentation is that of a pseudodivertículo the drive (not the diverticulum containing all layers of the colon wall - the mucosa and submucosa protrude through the muscle layer and are covered by serosa).
There are four well-defined around the intestinal circumference points where the vasa recta penetrate the circular muscle layer. The vessels enter the wall on each side of tapeworm mesenteric and antimesenteric mesenteric border of the two tapeworms. Not formed distal colo to the junction colo retossigmóidea diverticula as tapeworms colo coalesce to form a longitudinal muscle layer.
The penetration points of the straight vessels in the intestinal wall are areas of weakness
designing. The cleavage colo may occur as a result of increased intracolonic pressure in certain areas. colo Represents strong muscular contractions of the wall that would serve to propel the luminal contents or interrupt their passage. The individual pressures in the chambers are temporarily higher than those found when the colon is not segmented. The segmentation of the colon in diverticulosis is exaggerated, causing colo occlusion of both ends of the chambers, resulting in high pressure inside.
The sigmoid colon is usually affected, probably due to its smaller size. Laplace's Law explains the development by the equation P = kT / R. (Where P is pressure, K is a constant, T is the wall tension and R is the radius). Most complications, however, is located in this area.
subclinical local inflammation to generalized peritonitis with free perforation handle.
thickened food particles can cause erosion of the diverticular wall, which progresses to inflammation, focal necrosis and perforation (micro or macro). The clinical manifestation of drilling depends on its size and how strong is your buffering by the body. Perforations, if well controlled, resulting in formation of an abscess, while the incomplete packing can lead to free punching.

The diagnosis made only with clinical data is incorrect in 33% of cases.
