==Overview==
Ischemic colitis must be differentiated from the many other causes of [[abdominal pain]], [[lower gastrointestinal bleeding|rectal bleeding]], and [[diarrhea]] such as [[infection]], [[inflammatory bowel disease]], [[diverticulosis]], or [[colon cancer]]. It is also important to differentiate ischemic colitis, which often resolves on its own, from the more immediately life-threatening condition of [[acute mesenteric ischemia]] of the [[small bowel]].


Ischemic colitis must be differentiated from the many other causes of [[abdominal pain]] and [[lower gastrointestinal bleeding|rectal bleeding]] (for example, [[infection]], [[inflammatory bowel disease]], [[diverticulosis]], or [[colon cancer]]).
==Differentiating ischemic colitis from other Diseases==
 
The differential of ischemic colitis is as follows:<ref name="pmid14702426">{{cite journal| author=Thielman NM, Guerrant RL| title=Clinical practice.

It is also important to differentiate ischemic colitis, which often resolves on its own, from the more immediately life-threatening condition of acute mesenteric ischemia of the [[small bowel]].
* The symptoms of colitis such as [[diarrhea]], especially [[Dysentery|bloody diarrhea]], and [[abdominal pain]] are seen in all forms of [[colitis]].
 
* The table below lists the [[differential diagnosis]] of common causes of colitis:

Overview

Ischemic colitis must be differentiated from the many other causes of abdominal pain, rectal bleeding, and diarrhea such as infection, inflammatory bowel disease, diverticulosis, or colon cancer. It is also important to differentiate ischemic colitis, which often resolves on its own, from the more immediately life-threatening condition of acute mesenteric ischemia of the small bowel.

Differentiating ischemic colitis from other Diseases

The differential of ischemic colitis is as follows:[1][2]

Diseases History and Symptoms Physical Examination Laboratory findings
Diarrhea Rectal bleeding Abdominal pain Atopy Dehydration Fever Hypotension Malnutrition Blood in stool (frank or occult) Microorganism in stool Pseudomembranes on endoscopy
Allergic Colitis + ++ + ++ ++
Chemical colitis + ++ ++ + + ++ +
Infectious colitis ++ ++ ++ +++ +++ ++ + ++ ++ +
Radiation colitis + ++ + + + ++
Ischemic colitis + + ++ + + + + ++
Drug-induced colitis + + ++ + ++ +

The differential diagnosis of abdominal pain are:
