Diverticulosis and diverticulitis
The presence of diverticula is known as diverticulosis
(die-vur-tik-yoo-LOE-sis).
When one or more of the pouches become inflamed,
and in some cases infected, that condition is known as
diverticulitis (die-vur-tik-yoo-LIE-tis).
Diverticulitis can cause severe abdominal pain, fever,
nausea and a marked change in the bowel habits.

under pressure. This causes marble-sized pouches to protrude
through the colon wall.
Diverticulitisoccurs when diverticula traumatized or inflamed ,
resulting in inflammation, and in some cases, infection.
