There is erosive gastritis, for which the common causes are stress, alcohol, some drugs, such as aspirin and other nonsteroidal anti-inflammatory drugs , and Crohn's disease. And, there is non-erosive gastritis, for which the most common cause is a Helicobacter pylori infection. [15] [1]
Reactive gastropathy is morphologically distinct entity [3] [4] 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.
Most patients with portal hypertensive gastropathy have either a stable or improving course in the appearance of the gastropathy on endoscopy.However, according to retrospective data, roughly one in seven patients with portal hypertensive gastropathy will develop bleeding (either acute or chronic) attributable to the gastropathy.

Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion," in this context means damage that is limited to the mucosa (which consists of three distinct layers: The epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), basement membrane, and lamina propria).
Atrophic gastritis under low power. H&E stain. Autoimmune metaplastic atrophic gastritis (AMAG) is an inherited form of atrophic gastritis characterized by an immune response directed toward parietal cells and intrinsic factor. [6] Achlorhydria induces G cell (gastrin-producing) hyperplasia, which leads to hypergastrinemia.
Stomach diseases include gastritis, gastroparesis, Crohn's disease and various cancers. [1] The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. The stomach connects to the esophagus above and to the small intestine below.
The pathogenic mechanisms are similar to those of erosive gastritis. [5] The pathogenesis of stress ulcer is unclear but probably is related to a reduction in mucosal blood flow or a breakdown in other normal mucosal defense mechanisms in conjunction with the injurious effects of acid and pepsin on the gastroduodenal mucosa. [6]
Inflammation of the stomach by infection from any cause is called gastritis, and when including other parts of the gastrointestinal tract called gastroenteritis. When gastritis persists in a chronic state, it is associated with several diseases, including atrophic gastritis, pyloric stenosis, and gastric cancer.
