Studies to date have suggested that there is a difference in gastroesophageal reflux disease (GERD) prevalence between geographical locations. The prevalence of GERD is lowest in France and Italy. Conversely, a GERD prevalence of 43% has been reported for Germany, the highest percentage prevalence seen in all the seven major markets. Traditionally, the prevalence of GERD in Japan and the Far East has been lower than in the West, although more recent studies have pointed to an increase in reported cases, which may be the result of improved diagnostic techniques, and more frequent recognition of the condition.
