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 is a process of chronic inflammation of the gastric mucosa of the stomach, leading to a loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues.
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.
The VacA gene encodes for vacuolating cytotoxin, but its mechanism of causing peptic ulcers is unclear. Such stomach mucosal inflammation can be associated with hyperchlorhydria (increased stomach acid secretion) or hypochlorhydria (reduced stomach acid secretion). Inflammatory cytokines inhibit the parietal cell acid secretion.
Gastritis The folds become very thick due to inflammation. [7] Peptic ulcer disease Ulcers cause breaks in the mucosa and cause erosion of the sub-mucosa. Zollinger-Ellison syndrome Gastrin levels increase due to tumors, which cause an increase in the gastric fold size. [7] Ménétrier's disease The mucosa pits are in excess causing thickening ...
Early radiation enteritis is caused by cell death of the crypt epithelium and subsequent mucosal inflammation, however usually subsides after the course of radiation therapy is completed. Delayed radiation enteritis is a chronic disease which has a complex pathogenesis involving changes in the majority of the intestinal wall.
However, recent research indicates that the gastric mucosa which secretes gastric acid is acid-resistant. [citation needed] There are many types of chronic disorders which affect the stomach. However, since the symptoms are localized to this organ, the typical symptoms of stomach problems include nausea, vomiting, bloating, cramps, diarrhea and ...
The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm ...
