diverticulosis

diverticulosis a disorder characterized by the presence of diverticula, which are small, usually multiple saclike protrusions through the wall of the colon (large intestine ). Diverticula usually do not cause symptoms unless they become inflamed, in which case the condition is called diverticulitis. Symptoms of diverticulitis vary and may include abdominal pain, fever, bleeding, and diarrhea or constipation. Treatment includes bed rest, antibiotics, and a soft diet.

Diverticulosis becomes more common as people grow older, and it is estimated that more than 50% of people in Western countries acquire the condition by age 80. Many physicians believe that lack of fiber or bulk in the diet is a contributing factor in diverticulosis.

diverticulosis (dy-ver-tik-yoo-loh-sis) n. a condition in which diverticula exist in a segment of the intestine without evidence of inflammation (compare diverticulitis).

diverticular disease Diverticulosis is the presence of pouch‐like hernias (diverticula) through the muscle layer of the colon, associated with a low intake of dietary fibre and high intestinal pressure due to straining during defecation. Faecal matter can be trapped in these diverticula, causing them to become inflamed, causing pain and diarrhoea, the condition of diverticulitis. See also gastro‐intestinal tract.
