Irritable bowel syndrome (IBS) prevalence rates are based on diagnostic criteria, the basis for case definitions. Diagnostic criteria have a substantial impact on prevalence rates, which are significant for understanding burden of disease, comparing global subpopulations, generating pathophysiologic research, allocating of health care and research resources, and incentivizing and prioritizing new treatments. There are substantial methodological pitfalls in epidemiologic research, so determining ...

ABSTRACT null null Background and Aims null Over several decades, changes in health care have negatively impacted meaningful communication between the patient and provider and adversely affected their relationship. Under increasing time pressure, physicians rely more on technology than face-to-face time gathering data to make clinical decisions. As a result, they find it more challenging to understand the illness context and fully address patient needs. Patients experience dissatisfaction and a ...

ABSTRACT null null Background & Aims null Individuals with celiac disease (CD) can experience persisting gastrointestinal symptoms despite adhering to a gluten-free diet (GFD). This may be due to functional gastrointestinal disorders (FGIDs), although there is little data on its prevalence and associated factors. null null null Methods null An online health questionnaire was completed by adult members of Celiac UK in October 2018. The survey included validated questions on Rome IV FGIDs, non-gas...

BACKGROUND AND AIMS Conditions such as irritable bowel syndrome (IBS), functional dyspepsia and functional constipation are among the prevalent gastrointestinal disorders classified as disorders of gut brain interaction (DGBI), which can adversely affect the lives of sufferers. This study aimed to assess the degree and consequences of overlapping DGBI in a large population-based global scale. METHODS Internet survey data from 54,127 adults (49.1% females) in 26 countries were analyzed by 4 GI an...

OBJECTIVE The aim of this study was to compare the use of psychological defense mechanisms and corporeal discourse among patients with irritable bowel syndrome (IBS), medical personnel and healthy volunteers. METHODS All participants completed an identical battery of questionnaires: a demographic questionnaire, the Corporeal Discourse Questionnaire, the Defense Style Questionnaire and a Visual Analogue Scale for situational anxiety and depression.

Abstract: Background & Aims Individuals with hypermobility spectrum disorder or hypermobile Ehlers-Danlos Syndrome (HSD/hEDS) are increasingly encountered by gastroenterologists and pose complex clinical challenges. Uncontrolled studies have found functional gastrointestinal disorders (FGIDs) to be common in patients with HSD/hEDS. Some patients have somatic symptoms (medically unexplained symptoms) that might affect FGIDs. We performed a case–control study to determine the prevalence of and fac...

Abstract Background & Aims Although functional gastrointestinal disorders (FGIDs), now called disorders of gut–brain interaction, have major economic effects on healthcare systems and adversely affect quality of life, little is known about their global prevalence and distribution. We investigated the prevalence of and factors associated with 22 FGIDs, in 33 countries on 6 continents. Methods Data were collected via the internet in 24 countries, personal interviews in 7 countries, and both in 2 c...

Goals Assess neoplasia and polypectomy-related adverse event (AE) rates in gastric hyperplastic polyps (GHPs). Background GHPs carry a risk of neoplastic transformation. The rate of neoplastic transformation and the risk of polypectomy-related bleeding are unclear in the West, as data are derived from Asian or small studies. The authors aimed to determine the rate of dysplasia and intraprocedural AEs in GHP polypectomies in a western cohort. Study A retrospective study of 591 GHPs >1 cm resected...

Background Individuals with hypermobility spectrum disorders/hypermobile Ehlers‐Danlos syndrome (HSD/hEDS) frequently fulfill criteria for Rome IV functional gastrointestinal disorders (FGIDs). Postural orthostatic tachycardia syndrome (POTS) is also commonly reported in HSD/hEDS and may impact on co‐morbidity with and severity of FGIDs, although this remains to be studied. We determined the impact of concomitant POTS and HSD/hEDS on their association with Rome IV FGIDs. Methods With the help of...

Abstract Objective Although stress is an important component of irritable bowel syndrome (IBS) pathophysiology, the possibility that work-related stress is implicated in the pathophysiology of IBS has not been widely studied. This study aimed to examine whether job strain (a combination of high job demands and low control at work) and/or burnout, the outcome of a gradual depletion of energetic resources resulting from chronic exposure to work-related stress, are associated with IBS. Methods Fift...
