This is similar to what happens when an inner tube bulges through a tire. When the pouches develop, you have diverticul osis . When the pouches become inflamed or infected, your condition is called diverticul itis .
Pressure increases with hard stool.
A high-fiber diet may decrease your risk of having diverticula by helping to soften your stool and to make it easy to pass. Diverticulosis is more common in developed or industrialized countries such as the United States, England, and Australia, where diets are low in fiber. The disease is rare in Africa and Asia, where people eat high-fiber foods. Bleeding can be severe and often stops by itself. High-fiber foods including fruits, vegetables, and grains contain elements that your body cannot digest and are passed through your colon.
