Diverticulitis by Ray Sahelian, M.D.
Diverticulosis is a condition whereby diverticula (small pouches) develop in the lining of the large intestine, extending into and through the muscular tissue surrounding the intestine. If these pouches become infected or inflamed, the condition becomes known as diverticulitis. Acute diverticulitis is a condition in which diverticula in the colon rupture. The rupture results in infection in the tissues that surround the colon.
Acute diverticulitis symptoms
Acute diverticulitis can cause fever, malaise, elevated
white cell count and other symptoms, characteristics that should guide
physicians when considering referral for a CT scan.
The demographics of acute diverticulitis in the United
States are changing. In acute diverticulitis, a common intestinal disease
related to a low-fiber diet, increased pressure causes pouches, or diverticula,
to bulge out in the wall of the intestines. Bacterial infections can develop and
cause serious complications, such as perforations.
Even though most medical textbooks suggest that acute diverticulitis is
primarily confined to elderly patients, the majority of cases occur in patients
age 50 or younger.
Diverticulitis treatment
In patients with asymptomatic diverticulosis, a fiber-rich diet is used to
reduce intraluminal pressure and slow down the worsening of the disease. Fiber
supplementation is also indicated in symptomatic diverticulosis in order to get
symptom relief and prevent acute diverticulitis. A combination of soluble fiber,
like glucomannan, and poorly absorbed antibiotics, like rifaximin, given 7-10
days every month is a good treatment choice. For uncomplicated diverticulitis
the standard therapy is liquid diet and oral antimicrobials, usually
ciprofloxacin and metronidazole. Hospitalization, bowel rest, and intravenous
antibacterial agents are mandatory for complicated diverticulitis. Once in
remission, continuous fiber intake and intermittent course of rifaximin may
improve symptoms and reduce diverticulitis recurrence.
