Diverticulitis

,

This editorial illustration was created for a May 2013 cover of American Family Physician. The image summarizes Diverticulitis, a common digestive disease which involves the formation of pouches (diverticula) within the bowel wall. This process is known as diverticulosis, and typically occurs within the large intestine, or colon, although it can occasionally occur in the small intestine as well. Diverticulitis results when one of these diverticula becomes inflamed.

Patients often present with the classic triad of left lower quadrant pain, fever, and leukocytosis (an elevation of the white cell count in blood tests). Patients may also complain of nausea or diarrhea; others may be constipated.

Less commonly, an individual with diverticulitis may present with right-sided abdominal pain. This may be due to the less prevalent right-sided diverticula or a very redundant sigmoid colon. Some patients report bleeding from the rectum.
Diverticulitis

The most common symptom of diverticulitis is abdominal pain. The most common sign is tenderness around the left side of the lower abdomen. If infection is the cause, then nausea, vomiting, fever, cramping, and constipation may occur as well. The severity of symptoms depends on the extent of the infection and complications. Diverticulitis may worsen throughout the first day, as it starts as small pains and/or diarrhea, and may slowly turn into vomiting and sharp pains.

Foods such as seeds, nuts, and corn were, in the past, thought by many health care professionals to possibly aggravate diverticulitis. However, recent studies have found no evidence that suggests the avoidance of nuts and seeds prevents the progression of diverticulosis to an acute case of diverticulitis. Not only has this research shown that they do not appear to be aggravating the diverticulitis, but it appears that a higher intake of nuts and corn could in fact help to avoid diverticulitis in male adults. Most cases of simple, uncomplicated diverticulitis respond to conservative therapy with bowel rest and antibiotics. Despite being recommended by several guidelines, the use of antibiotics in mild cases of uncomplicated diverticulitis is supported with only “sparse and of low quality” evidence, with no evidence supporting their routine use. However, recurring acute attacks or complications, such as peritonitis, abscess, or fistula may require surgery, either immediately or on an elective basis.

People may be placed on a low residue diet. This low-fiber diet gives the colon adequate time to heal without needing to be overworked. Later, patients are placed on a high-fiber diet.
