Diverticular disease is characterized by the presence of diverticula in the colon wall, due to an increase in intraluminal pressure. Diverticula are pockets that usually form on the left side of the colon walls, although it can occupy the entire colon. When an increase in intraluminal pressure produces a pulse of the muscosa occurs through colonic muscle layers in their weak points, which correspond to the points where the neurovascular bundles penetrate. In most cases, diverticular disease have no symptoms, and only when there is bleeding or complications may appear diverticulitis. Diverticulitis (that is infection of the diverticula) in turn can cause abdominal pain, fever and chills. More serious complications can even cause an ruputura or fistulae that require surgery. The treatment of diverticular disease is essential and based on regular consumption of dietary fiber. In the case of diverticulitis, treatment should be done by antibiotics (oral or intravenous), restrictions on food and stool softeners.
