Epidemiology investigates frequency, causes and distribution of a disease in a population from a specific geographic area to detect whether environment plays a role in health-related problems. The frequency of a disorder is evaluated by two parameters:
  1. 1.

    Incidence: number of new cases per 100 000 inhabitants per year;

  2. 2.

    Prevalence: percentage of cases in an examined population. Gastroesophageal reflux (GER) is a condition characterised by the presence of a constant feature, e.g. reflux of gastric juice into the oesophagus, and inconstant aspects (not always observed), e.g. clinical symptoms or oesophagitis.
