Mr. Fruge is 60 years old. After performing a routine colonoscopy, his gastroenterologist tells him everything is normal, except that she noticed the presence of several diverticula in his colon. The physician suggested he speak with the clinic dietitian regarding dietary recommendations.What causes diverticula to develop?
Diverticula are caused by low-fiber diets, which require more vigorous muscle contractions, increasing pressure within the segments immediately adjacent to the circular muscles. This increase in pressure may induce small areas of intestinal tissue to weaken and balloon outward over time.
