Answer

Epidemiologic studies reflect the widespread incidence of gastritis. In the United States, it accounts for approximately 1.8-2.1 million visits to doctors' offices each year.

Data from a national administrative database (2009-2011) revealed standardized estimated prevalence rates of 6.3 per 100,000 population for eosinophilic gastritis and 3.3 per 100,000 population for eosinophilic colitis; women were affected more often. [5]

Gastritis affects all age groups; however, this condition is especially common in people older than 60 years. The incidence of H pylori infection increases with age.
