4 Things to Know About Diverticular Disease

David Johnson, MD, chief of gastroenterology at Eastern Virginia Medical School in Norfolk, discussed diverticulosis and diverticulitis and debunked four associated myths in a recent Medscape report.

Myths

•    Diverticulosis often progresses to diverticulitis. Literature has stated 10 to 25 percent of diverticulosis cases will progress to diverticulitis. In a recent study of more than 2,200 patients over a period of 11 years, the incidence of diverticulitis was 4.3 percent. The progression from diverticulosis to diverticulitis may be less common than previously thought.
•    Constipation raises diverticulosis risk. There is a lack of data to support the belief that a high-fiber diet and lack of constipation lessen the chance of diverticulosis or diverticulitis.
•    Diverticulitis cannot be predicted. Vitamin D levels can be used to assess the risk of diverticulitis or associated complications. A study found that patients with low serum hydroxyvitamin D levels are more likely to have diverticulitis.
•    Diverticulitis reoccurrence can't be prevented. Multiple trials have found 5-aminosalicylic acid to have preventative benefits. Combined use of 5-ASA and probiotics may be an effective preventative measure.
