How does diverticulosis turn into diverticulitis? how do you know when latter develops?

Pain: Diverticulosis are pockets in the colon thought to be caused by high fat low fiber diet. When a nidus or irritant gets lodged in a pocket the area becomes inflamed and you get diverticulitis. Signs include severe abdomen pain, cramping, possibly bloody stool and diarrhea. Confirmation is usually done with labs and ct.

Infection: Diverticulosis is often with no symptoms. If one of the diverticula becomes obstructed or infected, you develop diverticulitis, with lower abdominal pain, fever, elevated WBC and ct scan confirming diverticulitis.

Diverticulitis: Assuming you have diverticulosis in the first place, the symptoms of diverticulitis would include fever, chills, sweats, nausea, diarrhea and abdominal pains usually either in the lower left or lower right aspect. Diverticulitis comes from a ruptured diverticulum.
