The importance of health-related quality of life (HRQOL) continues to grow, as clinicians and clinical researchers have recognized the impact of the functional gastrointestinal disorders. Limited information is available on the performance of HRQOL questionnaires in Asia. Furthermore, the effect across different cultural settings of functional gastrointestinal disorders on HRQOL has been little studied in Eastern countries. We summarized recent studies on HRQOL in Korean patients with functional gastrointestinal disorders as well as other Asian literatures. Functional gastrointestinal disorders-related symptoms had a great effect on the HRQOL of Korean patients. These results and their considerable prevalence in Korea indicate that functional gastrointestinal disorders have a substantial social impact in this country.
