Acute appendicitis
QuestionChoice
This is the other type of irritable bowel disease. Unlike ulcerative colitis, this can affect the whole GI tract from the mouth to the anus and is non-continuous with healthy sections of the gut. It is less common for stool to be full of blood and mucous and tenesmus is more commonly observed in ulcerative colitis. Hence, Crohn's is less likely in this patient.
