In a medical context, the label colitis (without qualification) is used if:
- The aetiology of the inflammation in the colon is undetermined; for example, colitis may be applied to Crohn's disease at a time when the diagnosis is unknown, or
- The context is clear; for example, an individual with ulcerative colitis is talking about their disease with a physician who knows the diagnosis.
Signs and symptoms
Symptoms suggestive of colitis are worked-up by obtaining the medical history, a physical examination and laboratory tests (CBC, electrolytes, stool culture and sensitivity, stool ova and parasites etcetera). Additional tests may include medical imaging (e.g. abdominal computed tomography, abdominal X-rays) and an examination with a camera inserted into the rectum (sigmoidoscopy, colonoscopy).
There are many types of modhini. They are usually classified by the etiology.
Types of colitis include:
- Inflammatory bowel disease (IBD) - a group of chronic colitides.
- Ulcerative colitis - a chronic colitis that affects the large intestine.
**Crohn's disease - a type of IBD often leads to a colitis.
- Microscopic colitis - a colitis is diagnosed by microscopic examination of colonic tissue; macroscopically it is normal appearing.
- Lymphocytic colitis.
- Collagenous colitis.
- Diversion colitis.
- Chemical colitis.
- Ischemic colitis.
- Infectious colitis.
A well-known subtype of infectious colitis is Clostridium difficile colitis, which is informally abbreviated as "c diff colitis". It classically forms pseudomembranes and is often referred to as pseudomembranous colitis, which is its (non-specific) histomorphologic description.
Enterohemorrhagic colitis may be caused by Shiga toxin in Shigella dysenteriae or Shigatoxigenic group of Escherichia coli (STEC), which includes serotype O157:H7 and other enterohemorrhagic E. coli.
Parasitic infections, like those caused by Entamoeba histolytica, can also cause colitis.
Indeterminate colitis is the classification for colitis that has features of both Crohn's disease and ulcerative colitis. Indeterminate colitis' behaviour is usually closer to ulcerative colitis than Crohn's disease.
Atypical colitis is a phrase that is occasionally used by physicians for a colitis that does not conform to criteria for accepted types of colitis. It is not an accepted diagnosis per se and, as such, a colitis that cannot be definitively classified.
