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.
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.
This condition can be blamed for many ailments like kidney stones, constipation, liver problems, weight gain, blood pressures problems, joint and muscle damage, premature aging and gastritis or ...
Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Since the abdomen contains most of the body's vital organs, it can be an indicator of a wide variety of diseases.
While chronic life stress was once believed to be the main cause of ulcers, this is no longer the case. [27] It is, however, still occasionally believed to play a role. [ 27 ] This may be due to the well-documented effects of stress on gastric physiology, increasing the risk in those with other causes, such as H. pylori or NSAID use.
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.
The intensity of chronic inflammation is related to the cytotoxicity of the H. pylori strain. A greater cytotoxicity will result in the change from a non-atrophic gastritis to an atrophic gastritis, with the loss of mucous glands. This condition is a prequel to the development of peptic ulcers and gastric adenocarcinoma. [149]
