Doyle is having pain in his abdomen from inflammation of his digestive tract. Which disorders might his doctor record in his chart as the most likely diagnosis?

Colitis is inflammation of the colon, and gastroenteritis is inflammation of the stomach and intestines. Both can cause abdominal pain and involve the digestive tract, so the doctor might consider either diagnosis. Cancer and periodontal disease do not both fit these symptoms; periodontal disease affects the tissues around the teeth.
