Final answer:
The term for inflammation of the abnormal intestinal pouches is diverticulitis. It occurs when diverticula in the large intestine get infected and inflamed, often requiring antibiotics or even surgery for treatment.
Step-by-step explanation:
The term for inflammation of abnormal sac-like herniations of the intestinal wall is diverticulitis. This condition arises when the diverticula, which are pouches that form in the lining of the large intestine, become infected and inflamed. Symptoms of diverticulitis may include severe abdominal pain, fever, and a change in bowel habits, among others. While diverticulosis itself is the presence of these pouches without inflammation, the onset of inflammation and infection leads to diverticulitis. Treatment often involves antibiotics, dietary modifications, and in some cases, surgery. It's a serious condition that can lead to complications such as peritonitis, where the infection spreads to the lining of the abdomen, if not managed appropriately.
