Who is susceptible to Diverticulosis?!


Question: Who is susceptible to Diverticulosis?
I am doing an Anatomy project and only discovered that typically 10% of Americans age 40 have diverticulosis and by age 60 it's half of the population. Do you have any more specific reasons as to why someone may be susceptible to diverticulosis or is it unknown?

Answers:

Diverticular disease occurs when the fibre content of the diet is low. Physics suggest the narrower a tube, the higher the pressure inside it. A high fibre diet produces a large volume of stool and colons with wide diameters. This means lower pressure. In societies where much less fibre is eaten, the colon diameter is smaller and the pressure is higher. This increased pressure literally pushes the pockets of bowel lining out between the thickened muscle bundles forming diverticula.
In developed countries diverticular disease is present in 1/3 of the population by the age of 50 years and in 2/3 of the population by the age of 80 years.

The majority have no symptoms but 10-20% may develop diverticulitis or diverticular bleeding.
