Diverticula can perforate and cause peritonitis, and/or severe bleeding. Diverticulitis occurs more often in older adults and affects males more frequently than females.

what happen in severe cases of ulcerative colitis ?

it can involve the entire length of the colon. Mucosa and submucosa become hyperemic (increase in blood flow), and the colon will become edematous and reddened. It can lead to abscess formation. ● Edema and thickened bowel mucosa can cause partial bowel obstruction. Intestinal mucosal cell changes can lead to colon cancer or insufficient production of intrinsic factor, resulting in insufficient absorption of vitamin B12 (pernicious anemia). - loss the ability to absorb nutrient because scar tissue develops and causes loss of elasticity.
