Epidemiology
Data for the incidence and prevalence of gastritis are not available. Dyspeptic symptoms are reported in 10% to 20% of patients taking non-steroidal anti-inflammatory drugs (NSAIDs), although the prevalence may range from 5% to 50%.[17][18] In the United States, dyspeptic symptoms affect up to 25% of the population; non-ulcer dyspepsia (including gastritis) contributes to the diagnosis in about 50% of patients referred for upper endoscopy.[19] North European or Scandinavian ancestry is a recognised risk factor for autoimmune gastritis.[10] The prevalence of Helicobacter pylori infection is higher in developing countries and is impacted by a multitude of factors, including geography, age, strain virulence, environmental factors, and socio-economic status.[20]
