Diverticulitis typically develops in individuals over 40 with what dietary pattern?

• A. Under 20 and High Fiber Diet
• B. Over 40 and Low Fiber Diet
• C. High Fiber Diet
• D. Over 60 and High Fat Diet

Answer: (B)

Diverticulitis is more likely to occur when there are diverticula in the colon, and those diverticula form more readily when stool is small and hard, a situation common with a low-fiber diet. Over time, low fiber causes the colon to work harder to move stool, increasing intraluminal pressure and the chance that diverticula will develop. Once diverticula are present, they can become inflamed or infected, leading to diverticulitis. Age also plays a role, with risk rising in people over forty as the colon tends to become more vulnerable. A high-fiber diet, in contrast, adds bulk to stool and lowers pressure, reducing the likelihood of diverticula formation and inflammation. So the combination most often described is someone over forty who consumes a low-fiber diet. The other patterns do not fit this mechanism as well, since high fiber is protective and very young ages or high-fat patterns are not the typical scenario associated with diverticulitis.
