The most common causes of acute gastritis are infectious. Acute infection with H. pylori induces gastritis. However, H. pylori acute gastritis has not been extensively studied. Reported as presenting with sudden onset of epigastric pain, nausea, and vomiting, limited mucosal histologic studies demonstrate a marked infiltrate of neutrophils with edema and hyperemia. If not treated, this picture will  evolve into one of chronic gastritis. Hypochlorhydria lasting for up to 1 year may follow acute H. pylori infection. The less common of the two forms involves primarily the fundus and body.
