This study examined the prevalence of upper gastrointestinal (GI) symptoms and symptom groupings and determined impact on disability days in a nationally representative US sample.
A telephone survey of 21,128 adults was conducted including questions about the presence of upper GI symptoms during the past 3 months. Respondents were categorized as symptomatic (ie, reported GI symptoms once per month) or asymptomatic. The survey included questions about missed work, leisure activity, or household activity days. Symptom groupings were identified by using factor analysis, and cluster analysis was used to assign respondents into distinct groups on the basis of these symptom groupings.
The prevalence of an average of 1 or more upper GI symptoms during the past 3 months was 44.9%. The most common symptoms experienced during the past 3 months were early satiety, heartburn, and postprandial fullness. Factor analysis identified 4 symptom groupings: (1) heartburn/regurgitation; (2) nausea/vomiting; (3) bloating/abdominal pain; and (4) early satiety/loss of appetite. Five respondent clusters were identified; the largest clusters were primarily early satiety/fullness (44%) and gastroesophageal reflux disease-like symptoms (28%). Two small clusters reflected nausea and vomiting (7%) and a heterogeneous symptom profile (4%). Symptomatic respondents reported significantly more missed work, leisure, and household activity days than asymptomatic respondents (all P < .0001).
Factor analysis separated GI symptoms into groupings reflecting gastroesophageal reflux disease and dyspepsia: early satiety, postprandial fullness, and loss of appetite; bloating and abdominal pain/discomfort; and nausea and vomiting. These upper GI symptoms were associated with significant loss of work and activity days.

    • "In terms of drug therapy for FD, acid-suppressive and prokinetic drugs have been effective for dyspepsia,10 although high-quality studies investigating the true utility of these agents applicable for FD in a randomized and blinded fashion are still lacking.11 As it has been reported that the quality of life of FD patients is impaired,7,12 and that employees with FD have greater costs at all places of service and lower productivity than employees without FD,13,14 general physicians as well as gastroenterologists have to care for them intensively. However, there have been no massive analyses on explanation, prescription and motivation for FD. "

    ABSTRACT: Functional dyspepsia (FD) is one of the commonest diseases in the field of Internal Medicine. The Japanese Society of Gastroenterology (JSGE) has been enlightening the term and concept of FD. Aim of this survey was to elucidate the understanding status of FD and Rome criteria and attitude toward FD among Japanese internists. Data were collected at the time of lifelong education course for certified members of Japanese Society of Internal Medicine. Self-administered questionnaires were delivered to the medical doctors prior to the lectures. Analysis subjects were 1,623 (24-90 years old) internists among 1,660 medical doctors out of 4,264 attendees. The terms related to FD were known in 62.0-68.9% of internists, whereas 95.5% understood chronic gastritis. Internists who had been taking care of FD patients informed them as chronic gastritis (50.0%), FD in Japanese Kanji character (50.8%) and FD in Kanji and Katakana (18.6%). Logistic linear regression analysis revealed that positive factors for the understanding of FD and intensive care for FD patients were practitioner, caring many patients and certified physician by JSGE. Existence of Rome criteria was known in 39.9% of internists, and 31.8% out of them put it to practical use. The certified physician by JSGE was a positive factor for awareness, but not for utilization. The results suggest the needs of enlightening the medical term FD in Japan and revision of Rome criteria for routine clinical practice. Precise recognition of FD may enhance efficient patient-based clinical practice.

    ABSTRACT: Functional dyspepsia (FD) is a highly prevalent disease characterized by symptoms originating from the gastroduodenal region in the absence of underlying organic disease. The Rome III consensus made a distinction between meal-induced and meal-unrelated symptoms and proposed subdivision of FD into postprandial distress syndrome and epigastric pain syndrome. The applicability of this subdivision and the impact on management are areas of active research. So far, empirical approaches are still employed for the treatment of FD, although various therapeutic modalities for FD have been explored; acid-suppressive, prokinetic, and fundic relaxant drugs, antidepressants and psychological therapies. FD remains a challenge and presents unmet clinical needs.

    ABSTRACT: Dyspepsia is an upper gastrointestinal tract syndrome presenting epigastric pain and discomfort, fullness sensation, early satiety, nausea, vomiting, and belching. The prevalence of dyspepsia has been reported to be high all over the world. In this study, we reviewed studies reporting the prevalence of dyspepsia in Iran and discussed the probable risk factors of dyspepsia to shed light on future research on this topic. The four electronic databases of PubMed, Google Scholar, IranMedex, and Scientific Information Database were searched. The keywords for the electronic search were "dyspepsia" and "Iran". A manual search of the reference lists of the selected articles was also carried out. Two reviewers reviewed and identified articles independently and selected relevant studies based on our inclusion and exclusion criteria. Nine articles reporting the prevalence of dyspepsia in Iran were included. The reported prevalence ranged from 2.2% to 29.9%. The majority of studies have reported the prevalence of dyspepsia to be higher in women. Dyspepsia seems to be highly prevalent in Iran. Considering the wide range of data reported in different studies, conducting further population-based studies is necessary to investigate the epidemiology and risk factors of dyspepsia among Iranians.
