It is hard to determine the exact
incidence of diverticulosis (the formation of pouches in the wall of the large
intestine), because most people who have colon pouches do not have symptoms.
In general, diverticulosis becomes more likely with age.
About 20 out of 100 people who
have been diagnosed with diverticulosis develop diverticulitis. This occurs
when the pouches along the large intestine become inflamed or infected. Men and
women are affected almost equally.1
The spleen is a delicate, fist-sized organ under your left rib cage near your stomach. It contains special white blood cells that destroy bacteria and help your body fight infections. The spleen also makes red blood cells and helps remove, or filter, old ones from the body's circulation.
A layer of tissue entirely covers the spleen in a capsule-like fashion, except where veins and arteries enter the organ. This tissue, called the splenic capsule, helps protect the spleen from direct injury.
