Dyspepsia refers to group of commonly occurring upper gastrointestinal symptoms. The majority of patients with dyspepsia suffer from functional (nonulcer) dyspepsia. Although there is a lack of epidemiological data from population-based or patient cohort studies in Korea, the current understanding of this condition has been updated using data from various recent research studies, which have fac...

Dyspepsia is a common condition in the general population but data are lacking on the benefits of effective acid inhibition with proton pump inhibitors in functional dyspepsia. The results of the large, randomised, double blind clinical trials, BOND and OPERA, the Scandinavian PILOT study, and a follow up study, ENCORE, are reviewed. BOND, OPERA, and PILOT aimed to address the question of wheth...

Dyspepsia, according to the internationally accepted Rome criteria, refers to pain or discomfort centred in the upper abdomen; patients with predominant heartburn are excluded from this group, although minor or infrequent heartburn is commonly associated with dyspepsia. It is an important condition not only because it is common and costly, but because it may indicate the presence of serious dis...

BACKGROUND/AIM Management of dyspepsia may differ between countries. In Japan, Helicobacter pylori infection should be considered because of the high prevalence of the infection and the related diseases. I tried to propose an algorithm for stepwise diagnosis and treatment from uninvestigated dyspepsia to functional dyspepsia in clinical practice in Japan. METHODS A proposal was made from my p...

Impaired gastric accommodation is one of the most important etiologic factors in the pathophysiology of functional dyspepsia. Ultrasound is a potential alternative method to study changes in gastric volume as a reflection of gastric accommodation. Ultrasound is suitable for patients because it is a non-invasive, easily repeated and non-radioactive procedure, and a previous study has demonstrate...

BACKGROUND The use of proton pump inhibitors for the treatment of functional dyspepsia is controversial and the role of Helicobacter pylori infection in functional dyspepsia is uncertain. AIM To evaluate the efficacy of different doses of lansoprazole for the treatment of functional dyspepsia in Chinese patients. METHOD Patients with a clinical diagnosis of functional dyspepsia according to...

Background: The use of proton pump inhibitors for the treatment of functional dyspepsia is controversial and the role of Helicobacter pylori infection in functional dyspepsia is uncertain. Aim: To evaluate the efficacy of different doses of lansoprazole for the treatment of functional dyspepsia in Chinese patients. Method: Patients with a clinical diagnosis of functional dyspepsia according to ...

Symptomatic improvement of patients with functional dyspepsia after drug therapy is often incomplete and obtained in not more than 60% of patients. This is likely because functional dyspepsia is a heterogeneous disease. Although great advance has been achieved with the consensus definitions of the Rome I and II criteria, there are still some aspects about the definition of functional dyspepsia ...
