Diverticular disease is when problems occur due to diverticulosis, a benign condition defined by the formation of pouches (diverticula) from weak spots in the wall of the large intestine.

[2] The most common symptoms across the disease spectrum are abdominal pain and bowel habit changes such as diarrhea or constipation.

Otherwise, diverticulitis presents with systemic symptoms such as fever and elevated white blood cell count whereas SUDD and SCAD do not.

Treatment ranges from conservative bowel rest to medications such as antibiotics, antispasmodics, acetaminophen, mesalamine, rifaximin, and corticosteroids depending on the specific conditions.

[7] Many risk factors contribute to the development and severity of diverticular disease, such as Diverticulitis typically presents with tenderness in the left lower abdomen, fever, bowel habit changes such as constipation or diarrhea.

Laboratory abnormalities include elevated white blood count and inflammatory markers (C-reactive protein and erythrocyte sedimentation rate).

[8] SUDD clinically presents with left lower abdominal pain and bowel habit changes (predominantly diarrhea).

There is no systemic inflammation in SUDD, evident by lack of fever, normal white blood count and inflammatory markers.
