Infection of the stomach with H. pylori is not the cause of illness itself: over half of the global population is infected, but most individuals are asymptomatic. [7] [8] Persistent colonization with more virulent strains can induce a number of gastric and non-gastric disorders. [9]
Gastritis caused by H. pylori infection is termed Helicobacter pylori induced gastritis, and listed as a disease in ICD11. [6] [7] More than 80% of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology. [17]
Howard Steer observes H. pylori from biopsies of a patient with ulcers. [30] 1972 The first report of successfully using furazolidone (an antibacterial agent) to treat PUD in China. [31] 1974 Morozov observes H. pylori; he does not connect this discovery to PUD. [13] A well regarded study of PUD is published which does not mention bacteria. [30 ...
It can be caused by persistent infection with Helicobacter pylori, or can be autoimmune in origin. Those with autoimmune atrophic gastritis ( Type A gastritis ) are statistically more likely to develop gastric carcinoma (a form of stomach cancer ), Hashimoto's thyroiditis , and achlorhydria .

[1] Helicobacter pylori is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the nonlymphoma type, and various subtypes of ...
In 1999, a review of existing studies found that, on average, 40% of GERD patients also had H. pylori infection. [39] The eradication of H. pylori can lead to an increase in acid secretion, [ 40 ] leading to the question of whether H. pylori -infected GERD patients are any different from non-infected GERD patients.
In 1982, they performed the initial culture of H. pylori and developed their hypothesis on the bacterial cause of peptic ulcers and gastric cancer. [9] It has been claimed that the H. pylori theory was ridiculed by established scientists and doctors, who did not believe that any bacteria could live in the acidic environment of the stomach ...
