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.

Gastritis is the inflammation of the lining of the stomach. [1] It may occur as a short episode or may be of a long duration. [1] There may be no symptoms but, when symptoms are present, the most common is upper abdominal pain (see dyspepsia). [1]
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.
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), the basement membrane, and the lamina propria.
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.
Erythema (Ancient Greek: ἐρύθημα, from Greek erythros 'red') is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. [1] It occurs with any skin injury, infection, or inflammation .
Although ICD-10 classifies it under "Other gastritis" , and the lamina propria may contain mild chronic inflammatory infiltrate, Ménétrier disease is not considered a form of gastritis. [3] It is rather considered one of the two most well understood hypertrophic gastropathies; the other being Zollinger–Ellison syndrome .
The antrum has thicker skin cells in its walls and performs more forceful contractions than the fundus. The middle circular layer: At this layer, the pylorus is surrounded by a thick circular muscular wall, which is normally tonically constricted, forming a functional (if not anatomically discrete) pyloric sphincter , which controls the ...
