title: Epidemiology of functional dyspepsia.
abstract: Functional dyspepsia (FD) is the most common cause of dyspeptic symptoms. It refers to a heterogeneous group of symptoms located in the upper abdomen. The prevalence of dyspepsia is variable in different populations and is related to the different definitions of dyspepsia as inclusion criterias, variation in survey population and environmental factors. Epidemiologically some risk factors have been identified and underlying psychological disturbances have been shown to be important factors in FD. Age and ethnicity do not appear to be predictive of dyspepsia. A majority of patients suffering from significant levels of abdominal pain that interrupt daily activities and treatment remains unsatisfactory in this chronic condition.
