How Common is Diverticulosis?
The presence of diverticula, or diverticulosis, is incredibly common, with this risk increasing with age. Specifically, research indicates that only 1-2% of those under 30 have this condition. After age 60, roughly 40% of a given population will have diverticulosis. After the age of 80, that percentage increases even further, up to 66%.
How Common is Diverticulitis?
Someone has to already have diverticulosis in order for diverticulitis to develop. Most people with diverticula never progress to diverticulitis. Specifically, researchers have found that only about 10 to maybe 25% of those with diverticulosis will progress to diverticulitis.
