'''Inflammatory bowel disease (IBD)''' is an idiopathic group of disorders characterised by intestinal inflammatory changes, associated with persistent or recurrent gastrointestinal signs.  IBD can affect any part of the intestines and is classified according to the predominant cellular inflammatory infiltration.  Several histological types have been recognised, which are:

'''Inflammatory bowel disease (IBD)''' is an idiopathic group of disorders characterised by intestinal inflammatory changes, associated with persistent or recurrent gastrointestinal signs.  IBD can affect any part of the intestines and is classified according to the predominant cellular inflammatory infiltration.  Several histological types have been recognised, which are:

*[[Lymphocytic - Plasmacytic Enteritis|Lymphocytic - Plasmacytic Enteritis]] (LPE)

*[[Enteritis, Lymphocytic - Plasmacytic |Lymphocytic - Plasmacytic Enteritis]] (LPE)

*[[Eosinophilic Enteritis|Eosinophilic Enteritis]] (EE)

*[[Enteritis, Eosinophilic |Eosinophilic Enteritis]] (EE)

There is no underlying cause of IBD in 75% of cases.  They are thought to reflect an exaggerated or inappropriate response by the immune system to dietary, bacterial or self-antigens.  IBD is a diagnosis of exclusion.  Other differential diagnoses have to be investigated and ruled out before a diagnosis of IBD can be made.
