In gastroenterology, reactive gastropathy, also chemical gastropathy, is an abnormality in the stomach caused by chemicals, e.g. bile, alcohol, and characteristically has minimal inflammation.



The diagnosis is by examination of tissue, e.g. a stomach biopsy.

It is characterized, histologically, by:[1]

  1. foveolar hyperplasia with gland tortuosity and dilation,
  2. smooth muscle hyperplasia in the lamina propria, and
  3. scant or minimal inflammation, i.e. lack of large numbers of neutrophils and plasma cells.


Reactive gastropathy has a large number of causes, including:

Relation to gastritis

Reactive gastropathy is morphologically distinct entity[2][3] that can be separated from gastritis, which by definition has a significant inflammatory component.

As a reactive gastropathy may mimic a (true) gastritis symptomatically and visually in an endoscopic examination, it may incorrectly be referred to as a gastritis. Even aware of the underlying etiology of the pathologic process, e.g. NSAID use, the label "chemical gastritis" is applied to a chemical gastropathy. Etymologically, "gastritis", in this context, is a misnomer as the process is not predominantly inflammatory, i.e. the condition is not an -itis. This type of mislabeling is not uncommon in medicine. Steatohepatitis is another example of this; it is not a process with significant inflammation yet, confusingly, carries the -itis ending.
