Not sure if colitis or diverticulitis. What are the tests?

Same work up! When you have crampy abdominal pain with fevers or chills you can be diagnosed with colitis. Colitis is inflammation of the colon and can be due to infection, inflammatory bowel diseases or blood supply issues. Diverticulitis is caused when a small pocket in the colon pops and bacteria spills outside the wall of the colon. Ct scan is the best diagnostic tool.
Diverticulitis. Because diverticula by themselves usually do not cause problems, most people learn they have diverticulosis during routine screening examinations for colorectal cancer or during tests that check for other intestinal problems. Diverticulitis, on the other hand, is usually diagnosed during an acute attack.
