Prevalence Of Functional Dyspepsia Research Articles

Prevalence and risk factors of functional abdominal disorders according to a survey study among young people

Introduction. The etiological aspects of functional dyspepsia (FD) and irritable bowel syndrome (IBS) are not clear; the epidemiology of diseases in age groups and societies can help in understanding the starting causes of the pathology.Aim. To assess the risk factors for the development and prevalence of abdominal symptoms characteristic of FD and IBS among active users of Internet communities.Materials and methods. An anonymous online survey was conducted among medical university students. The questionnaire contains questions about complaints typical of FD and IBS over the past week, “alarm” symptoms, personal characteristics of the respondent and possible risk factors: smoking, family history, taking antibiotics, iron pills, non-steroidal anti-inflammatory drugs (NSAIDs).Results and discussion. The study included 983 respondents aged 18−26 years, 279 men and 704 women. Symptoms of unstudied regular (>1 time per week) postprandial dyspeptic disorders, bloating and abdominal pain were identified in 391 (39.8%) people, of which 29% were men and 44% were women (p < 0.001). Risk factors for regular unstudied disorders were having relatives with chronic gastrointestinal diseases (OR 2.05 [1.56, 2.70]); female gender (OR 1.92 [1.43, 2.59]); taking NSAIDs (OR 1.48 [1.14; 1.91]); for women – smoking (OR 2.24 [1.57; 3.18]). 6.5% of respondents met the criteria for FD, of which 23.4% had isolated epigastric pain, 26.6% had isolated postprandial distress syndrome, and 50% had combined FD. 2.5% of respondents met the criteria for IBS, 64% of whom had overlap syndrome with FD. The presence of FD was associated with NSAIDs use: r = 0.081; p = 0.011 (OR 1.95 [1.16; 3.30]).Conclusions. The prevalence of FD and/or IBS among people aged 18−26 years is 7.4%, with no significant differences between men and women. Taking NSAIDs can be considered as a factor contributing to the development of FD.

Multimorbidity of Allergic Diseases Is Associated With Functional Gastrointestinal Disorders in a Young Japanese Population.

Although certain allergic diseases have been reported to be associated with the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), it is unclear whether the presence of multiple allergic diseases further increases the prevalence of FD and IBS. The aim of this study is to determine this issue in young people. A cohort of 8923 Japanese university students was enrolled and diagnoses of FD and IBS were confirmed using Rome III criteria. Allergic disorders diagnosed at medical institutions were obtained by means of a self-administered questionnaire. The prevalence of FD, IBS, and their overlap was found to be 1.9%, 6.5%, and 1.1%, respectively. Pollen allergy was independently positively correlated with FD, IBS, and overlap of FD and IBS. Allergic rhinitis was positively linked to IBS. Drug allergy was positively associated with FD. The presence of multiple allergic diseases was positively correlated with FD and IBS (FD: adjusted OR for 2 allergic diseases: 1.95 [95% CI, 1.24-2.98], P for trend = 0.003; and IBS: adjusted OR for 1 allergic disease: 1.40 [95% CI, 1.15-1.69], 2 allergic diseases 1.47 [95% CI, 1.12-1.91], and 3 or more allergic diseases: 2.22 [95% CI, 1.45-3.28], P for trend = 0.001). Additionally, the concomitant existence of multiple allergic diseases was also demonstrated to have a trend that correlated with the overlap of FD and IBS (P for trend = 0.018). Allergic disease multimorbidity is positively correlated with the prevalence of FD and IBS in a young population.

Epidemiology of functional dyspepsia and gastroparesis as diagnosed in Flemish-Belgian primary care: A registry-based study from the Intego database.

Dyspepsia is a prevalent condition in the general population. Besides organic causes, the differential diagnosis of dyspepsia includes functional dyspepsia (FD) and gastroparesis (GP) which share similar pathophysiological mechanisms and clinical presentation. So far, no study investigated the prevalence of FD and GP in a primary care in Belgium. Data were obtained from Intego, a Flemish-Belgian general practice-based morbidity registration network. From 586,164 patients between 2000 and 2021, we selected patients with ICD-10 code for FD and GP. Patients with organic gastrointestinal diseases were excluded. We determined demographics and comorbidities of FD/GP. For prevalence and incidence calculation, we included those who consulted their general practitioners at least once in the given year. Pair-wise comparison was conducted to access the impact of comorbidities on risk of FD/GP. Between 2011 and 2021, the prevalence of FD/GP ranged from 1.03% to 1.21%. The incidence of FD/GP ranged from 109 to 142 per 100,000 adults. In total 5242 cases of FD/GP were identified. These cases shared commonly coexisting diagnoses of gastroesophageal reflux disease (18.8%), irritable bowel syndrome (17.1%), and chronic constipation (18.7%). Patients with somatization/anxiety/depression had significantly higher risk of FD/GP, compared to the control (OR 1.38, 95% CI 1.19-1.61, p < 0.01). The prevalence (1.03%-1.21%) and incidence (109-142/100,000) of FD/GP in primary care over last decade appear to conflict with epidemiological research in the general population. The discrepancies suggest a potential lack of awareness of FD and GP among physicians and/or patients in Flemish-Belgium.

Global prevalence of functional dyspepsia according to Rome criteria, 1990–2020: a systematic review and meta-analysis

Although functional dyspepsia (FD) is a common functional gastroduodenal disorder with a high socioeconomic burden, little is known about its global prevalence. Thus, we performed a comprehensive study to estimate long-term trends in the prevalence of FD. We searched PubMed/MEDLINE, Embase, and Google Scholar from 1990 to 2022 for population-based studies that reported the prevalence of FD in adults (≥ 18 years old) according to Rome I, II, III, or IV criteria. The prevalence of FD was extracted from included studies to obtain pooled prevalence with 95% confidence intervals (CI) and 95% prediction intervals. Subgroup analysis was performed according to certain characteristics, including geographic region. A total of 44 studies met the eligibility criteria, including 256,915 participants from 40 countries across six continents. The overall global pooled prevalence of FD was 8.4% (95% CI 7.4–.9.5). The prevalence was the highest in Rome I (11.9%; 95% CI 5.1–25.4) and lowest in Rome IV (6.8%; 95% CI 5.8–7.9). Developing countries showed a higher prevalence than developed countries (9.1% versus 8.0%), and prevalence was higher in women, irrespective of the definition used (9.0% versus 7.0%). The pooled prevalence gradually decreased from 1990 to 2020 (12.4% [8.2–18.3] in 1990–2002 versus 7.3% [6.1–8.7] in 2013–2020). The prevalence of FD differs by country, economic status, geographical region, and sex, and the global prevalence has been gradually declining. Despite the heterogeneity of sample population, our study estimates the current global burden of FD and provides information to heath care policy decisions.

Systematic Review of Clinical Guidelines for the Treatment of Functional Dyspepsia

An analysis of the literature data on the treatment of functional dyspepsia (FD) was performed. In the Kyrgyz Republic there have been no studies on the prevalence of FD, there are no protocols for diagnosis and management of patients with this pathology. We analyzed clinical recommendations on FD of the leading five world gastroenterological associations, the comparison of which showed the general principles of patient management, as well as some discrepancies.

Exercise is inversely associated with functional dyspepsia among a sample of Chinese male armed police recruits

BackgroundThere is no study evaluating the association between exercise and functional dyspepsia (FD) based on the Rome IV criteria. We aimed to investigate the prevalence of FD and evaluate the association between exercise and FD based on Rome IV criteria among a sample of Chinese armed police recruits.MethodsAn on-site questionnaire survey on FD among a sample of Chinese armed police recruits was conducted based on the Rome IV criteria in 2021. Potential confounders included age, body mass index (BMI), race, marriage, education, smoking, and drinking variables were adjusted.ResultsA total of 2594 recruits were enrolled, including 46 FD participants and 2548 non-FD participants. In the model adjusted for all demographic variables among participants excluding irritable bowel syndrome (IBS) and functional constipation (FC), compared with no exercise participants, 1 h < each exercise time ≤ 2 h (OR = 0.15, 95% CI: 0.03–0.77, P = 0.0230) was inversely associated with FD and compared with no exercise participants, mild exercise (OR = 0.09, 95% CI: 0.01–0.71, P = 0.0220) was significantly inversely associated with FD.ConclusionsThe incidence rate of FD in this sample Chinese armed police recruits was 1.77%, and 1 h < each exercise time ≤ 2 h and mild intensity exercise were independently inversely associated with FD. However, the causal relationship needs to be verified by further randomized controlled trials.

OGBN P44 Does laparoscopic fundoplication have a role in non-erosive reflux disease?

Abstract Background Non-erosive reflux disease (NERD) is a sub-group of gastro-oesophageal reflux disease (GORD) characterised by reflux related symptoms without endoscopic evidence of oesophageal mucosal erosion. Management can be challenging as the prevalence of functional dyspepsia and IBS-related symptoms is often high. This study was undertaken to examine symptom control after laparoscopic fundoplication in patients with NERD compared to those with oesophagitis associated GORD. Methods Patients who underwent laparoscopic fundoplication for NERD or GORD with oesophagitis between January 2017 and January 2022 were included in this study. Patients were asked to score their current symptoms using the modified DeMeester Clinical Symptom Score (CSS) and Gastrointestinal Symptom Rating Scale (GSRS), and then rate their satisfaction with the procedure. Results 14 patients who underwent surgery for NERD and 31 with oesophagitis associated GORD were included in this study, with a mean follow up of 3.4 years and 2.7 years respectively after surgery. 86% of NERD patients and 94% of oesophagitis patients reported an improvement in symptoms after surgery. There was a trend for higher symptom scores in NERD patients (NERD patients CSS 4.57±1.95, oesophagitis patients CSS 3.45±1.79, p=0.065; NERD patients GSRS 1.99±0.37, oesophagitis patients GSRS 1.72±0.49, p=0.069). NERD patients with higher pre-operative DeMeester scores from pH testing had lower GSRS scores (r=-0.616, p=0.043). Conclusions With careful patient selection and detailed pre-operative counselling, surgery can play a role in the management of NERD patients. Whilst post-operative symptom control may not be as good as that achieved with classical oesophagitis associated GORD, these findings suggest that NERD patients do achieve symptom improvement after laparoscopic fundoplication. Further research is needed to help identify other factors that predict response to surgery in NERD to optimise patient selection and improve shared decision making.

The prevalence and risk factors of functional dyspepsia among adults in low- and middle-income countries: An international cross-sectional study.

Dyspepsia is one of the most common chronic digestive diseases, which is due to underlying organic causes that can be detected, or causes that cannot be detected called functional dyspepsia (FD). There is no epidemiological study to date that measures the prevalence and risk factors of the FD in low- and middle-income countries, so this international cross-sectional study was conducted in 15 low- and middle-income countries from data previously published its protocol NCT05340400. Participants were recruited in the period from 22/April/2022 to 14/June/2022. The diagnosis of the FD was according to clinical manifestations. We determined the physical activity, daily stress, and fatigue of the participants. A large number of collaborators were chosen from different regions and institutions within each country to achieve diversity within the sample and reduce the probability of bias. Our study concluded that the prevalence of FD is much higher in low- and middle-income countries 37.9% [6.2%-44.2%], compared to high-income countries 10% [8%-12%], with a higher rate among the Afro-Caribbean race 47.9%. Sudan obtained the highest prevalence 44.3%, then Egypt 41.4%, while the lowest prevalence was in Algeria 25.7%. Moreover, there are many risk factors, including modifiable ones, such as severe stress, chronic fatigue, smoking, abnormal BMI, insufficient or too many hours of sleep, and previous infection with Covid-19, and non-modifiable ones such as advanced age, chronic diseases, and female sex. Highlighting the prevalence and increasing risk factors of FD in low- and middle-income countries should draw the attention of those responsible for health care in these countries and reduce the risk factors.

Truptighna mahakashaya is the remedy for Functional Dyspepsia

Functional dyspepsia (FD) is a clinical condition that brings the patient to the doctor with a wide range of symptoms. Many patients go on changing the consultants thinking that they are suffering with a complicated disease. The prevalence of FD is 20% worldwide. But, in India, the prevalence of FD ranges from 7-49% as per data published in one of the studies. Modern medical science treats the condition with PPI, H2 blockers, prokinetic drugs, Probiotics and many more to provide symptomatic relief. Likewise, Ayurveda, an age old health care system of India has developed its own way of treating this condition based on symptoms. Charaka has classified 500 drugs in 50 groups known as Maha kashaya. Each group of Maha kashaya consists of 10 drugs. Among these groups, a class known as Truptighna maha kashaya contains those drugs that relieve the early satiety and abdominal discomfort. But, the interesting fact is that these drugs have additional pharmacological actions that can be utilized to bring relief to the patients of FD of modern era. The drugs have 11 prominent actions that help relieving the symptoms and also prevent the complication of the condition. This class becomes a good alternative, appropriate, well-meant, nicely formulated remedy for functional dyspepsia.

Prevalence Survey of Functional Dyspepsia and Irritable Bowel Syndrome in Chinese College Students Based on Rome Ⅳ Diagnostic Criteria

To investigate the prevalence and risk factors of functional dyspepsia (FD) and irritable bowel syndrome (IBS) among college students in China. An online questionnaire survey of college students aged 17-35 from across China was conducted. The online questionnaire survey was supplemented by an offline survey. A total of 2025 valid samples were included for statistical analysis. χ 2 test and logistic regression were performed for statistical analysis. The prevalence of FD among college students who met the Rome Ⅳ diagnostic criteria was 5.5% (112/2025), with most of them, or 66.1% (74/112), suffering from postprandial discomfort syndrome (PDS). Smoking (odds ratio [ OR]=2.334, 95% confidence interval [ CI]: 1.187-4.589, P=0.014), depression ( OR=2.447, 95% CI: 1.421-4.214, P=0.001), and insomnia ( OR=1.947, 95% CI: 1.291-2.937, P=0.001) were positively correlated with the prevalence of FD. The prevalence of IBS was 1.9% (38/2025), with IBS-diarrhea dominant (IBS-D) being the most important subtype that accounted for 44.7%. Anxiety ( OR=3.63, 95% CI: 1.34-9.88, P=0.012) and insomnia ( OR=2.35, 95% CI: 1.18-4.68, P=0.015) were positively correlated with the prevalence of IBS. Based on Rome Ⅳ criteria, IBS and FD are not uncommon among Chinese university students. Psychological disorders and some related lifestyle factors may be related to the development of the disease. In the future, more series of studies based on different diagnostic criteria, different regions, and multiple factors should be conducted in China.

Research progress of treatment of functional dyspepsia with traditional Chinese medicine compound based on cell signal pathway.

Functional dyspepsia (FD) is the most common clinical gastrointestinal disease, with complex and prolonged clinical symptoms. The prevalence of FD is increasing year by year, seriously affecting the quality of life of patients. The main causes of FD are related to abnormal gastrointestinal dynamics, increased visceral sensitivity, Helicobacter pylori (HP) infection, intestinal flora disturbance and psychological factors. A review of the relevant literature reveals that the mechanisms of traditional Chinese medicine (TCM) in the treatment of FD mainly involve the following pathways:5-HT signal pathway, AMPK signal pathway,C-kit signal pathway, CRF signal pathway, PERK signal pathway,NF-κB signal pathway. Based on a holistic concept, TCM promotes gastrointestinal motility, regulates visceral sensitivity and alleviates gastrointestinal inflammation through multiple signal pathways, reflecting the advantages of multi-level, multi-pathway and multi-targeted treatment of FD.

Prevalence of combination of functional dyspepsia and irritable bowel syndrome: a meta-analysis of studies using the Rome III-IV Criteria

To systematize data on the prevalence of the combination of functional dyspepsia (FD) and irritable bowel syndrome (IBS) using the Rome IIIIV Criteria. A search in electronic databases MEDLINE/PubMed, EMBASE, and Cochrane was conducted. The depth of search was 17 years (from January 2006 to May 2022). Original publications from peer-reviewed periodicals that applied the Rome IIIIV Criteria for diagnosis of FD and IBS in an adult patient population with detailed descriptive statistics to allow the resulting data to be included in the meta-analysis were selected for final analysis. The final analysis included 38 studies involving 17,993 patients with FD and 15,883 patients with IBS. In the overall pool of studies using the Rome IIIIV Criteria, the pooled prevalence of FD in patients with IBS was 34.625% (95% confidence interval [CI] 28.15941.390), and the pooled prevalence of IBS in patients with FD was 37.549% (95% [CI] 31.51143.787). A random-effects model was used in the analyses since significant heterogeneity between results was found (p0.0001; I298%). Using the Rome III Criteria, the pooled prevalence of FD in patients with IBS was 31.993% (95% CI 26.13538.150; I2=98.17%), while the prevalence of IBS in patients with FD was 34.694% (95% [CI] 29.31940.273; I2=97,89%). An analysis of papers using the Rome IV Criteria demonstrated that the pooled prevalence of FD in patients with IBS was 42.614% (95% CI 18.58868.675; I2=98.97%), and the prevalence of IBS in patients with FD was 50.444% (95% CI 37.95662.904; I2=94,39%). This meta-analysis demonstrated that the prevalence of the combination of FD and IBS identified using the Rome IIIIV Criteria is high and is reported in approximately 1 in 3 patients with the functional gastrointestinal disorders concerned. The prevalence of a combination of FD and IBS identified using the Rome IV Criteria is at least 10% higher than that using the Rome III Criteria.

Functional Disorders of the Gastrointestinal Tract During the Pandemic of a New Coronavirus Infection

Aim. To analyze the literature data devoted to the study of the features of functional gastrointestinal diseases (FGID) during the pandemic of a new coronavirus infection.Key findings. Measures taken in connection with the pandemic of COVID-19 infection (introduction of lockdown, social isolation) leads to an increase in the level of depression and anxiety and, as a consequence, to an increase in the frequency and prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), as well as an increase in the severity of clinical symptoms of these diseases. In turn, the overcoming of COVID-19 infection contributes to an increase in the permeability of the mucous membrane of the gastrointestinal tract and the occurrence of its inflammatory changes, which lead to the development of postinfectious (postcovid) FD and postinfectious (postcovid) IBS.Conclusion. The problem of functional gastrointestinal diseases during the pandemic of a new coronavirus infection is very important and requires further research.

Association Between Eating Behavior, Frequency of Meals, and Functional Dyspepsia in Young Japanese Population.

Background/AimsFunctional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort.MethodsIn this study, we enrolled 8923 Japanese university students. FD is diagnosed based on the Rome III criteria. Eating habits and frequency of meals were investigated using a self-administered questionnaire.ResultsThe FD subjects had a younger mean age, a lower body mass index, and a lower proportion of men compared to the non-FD subjects. An independent positive association between skipping breakfast and/or lunch and FD was found (adjusted ORs were 1.60 [95% CI, 1.10-2.32] for breakfast and 2.52 [95% CI, 1.04-5.18] for lunch). Skipping dinner, extra meals (snacks) or midnight snacks was not associated with FD. The prevalence of FD in subjects eating 1, 2, and 3 meals per day was 4.8%, 2.2%, and 1.7%, respectively. The frequency of meals was independently inversely associated with prevalence of FD (adjusted ORs were 1 per day 2.72 [95% CI, 1.19-5.42], and 2 per day 1.69 [95% CI, 1.16-2.43], P for trend = 0.001).ConclusionsIn the young Japanese people, the frequency of meals may be independently inversely associated with prevalence of FD. In particular, skipping breakfast and/or lunch was associated with the prevalence of FD.

Association Between Body Mass Index and Functional Dyspepsia in Young Japanese People.

Background/AimsEvidence regarding the association between body mass index (BMI) and functional dyspepsia (FD) in the Asian population is limited. Further, no study has evaluated this issue in young people in Asian and Western populations. Thus, we aim to investigate this issue among young Japanese people.MethodsThe study subjects comprised of 8923 Japanese university students. BMI was divided into 4 categories (quartiles) on the basis of the study subjects’ distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, overweight, and obese was BMI < 18.5 kg/m2, 18.5 ≤ BMI < 25 kg/m2 (reference), 25 kg/m2 ≤ BMI < 30 kg/m2, and 30 kg/m2 ≤ BMI, respectively. The definition of FD was based on the Rome III criteria.ResultsThe prevalence of FD was 1.9% in this cohort. The lowest BMI was independently associated with FD after adjustment (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.46-3.67); P for trend = 0.001). The lowest BMI was independently associated with FD in women but not in men (OR, 2.94; 95% CI, 1.59-5.77; P for trend = 0.001). Leanness was independently associated with FD in total and in women but not in men (total adjusted OR, 2.01; 95% CI, 1.40-2.86) and women (OR, 2.19; 95% CI, 1.35-3.45). However, interaction analysis showed no significant difference for sex.ConclusionsAmong young Japanese people, BMI may be independently inversely associated with FD. Leanness may be an independent associated factor for FD in the young Japanese women.

High prevalence of functional dyspepsia in nonalcoholic fatty liver disease: a cross-sectional study.

Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

Effectivity of treatment for children with functional dyspepsia

Functional dyspepsia is very common in children of all ages and has a significant impact on the patient’s family and quality of life. Since the revision of the Rome IV criteria with the introduction of two subtypes, the prevalence of functional dyspepsia has increased, but currently no guidelines for the treatment are available. The aim of this study was to characterize patients, who have been diagnosed with functional dyspepsia and analyze the outcome of different treatments they received. This is a retrospective study of pediatric patients, diagnosed with functional dyspepsia between March 2017 and September 2020. All patients aged between 0 and18 years, who complained about gastric symptoms, have had a normal full blood count, a normal thyroid function, a negative coeliac screening, and most importantly normal macro- and microscopic findings on esophago-gastro-duodenoscopy were included in the study. Patient’s data were extracted from the medical record and three months after the performance of the endoscopy, parents were interviewed about the effect of the treatment. A total of 154 patients (66.2% female, 33.8% male) between the age of 4 and 18 years were included. In 113 (73.4%) the leading symptom was epigastric pain, followed by nausea (22; 14.3%) and a fifth of the patients (females: 18.6%; males: 21.2%) self-reported a current stressor in clinic. After receiving the diagnosis of a functional nature, families chose following treatments: 50 STW5 (32.3%, overall, 10.4% added dietary changes, alternative treatment, and psychology support), psychological support (22.7%), alternative treatments (e.g., hypnotherapy, meditation; 19.5%), dietary changes (12.9%), lifestyle changes (9.7%), no treatment (11%) and in 10.4% no treatment was needed as symptoms resolved after endoscopy had been performed. Only lifestyle changes (p = 0.03) in females, dietary changes (p = 0.035 for girls, p = 0.06 for boys) and STW5 in males (p = 0.043) showed a statistically relevant correlation regarding duration of symptoms. There was no correlation between location of symptoms and effectiveness of treatment. It is recommended to treat patients from both subgroups of functional dyspepsia differently, in accordance with the currently available explanatory models of underlying pathophysiological processes. In this cohort of patients this could not be verified. As all patients did benefit from any treatment, it is likely that the treatment itself was not accountable for the relief of symptoms, but that most patients benefit from education on the diagnosis, reassurance and a recommendation of a healthy lifestyle. Some patients might benefit from medications, small changes in the diet, psychological support or alternative treatment, but success depends on individual, unpredictable factor.

Positive Association Between Sleep Disturbance and Prevalence of Functional Dyspepsia in Japanese Young People.

Evidence regarding the association between sleep disturbance and functional dyspepsia (FD) remains limited in the young population. This study aimed to investigate the association between sleep disturbance and FD including subgroups among Japanese young people. Study subjects were 8923 university students. FD was defined according to the Rome III criteria. Subjects with FD were further categorized as having postprandial distress syndrome (PDS) or epigastric pain syndrome (EPS). Subjects completed a self-reported questionnaire assessing self-reported sleep duration, sleep disturbance, difficulty falling asleep, deep sleep disorder, nocturnal awakening, early awakening, and daytime sleepiness. The prevalence of FD was 1.9%. After adjustment, all types of sleep disturbances were independently positively associated with FD (total sleep disturbance: OR 4.11 [95% CI: 2.89-5.78], difficulty falling asleep: OR 3.97 [95% CI: 2.53-6.01], deep sleep disorder: OR 4.85 [95% CI: 3.06-7.40], nocturnal awakening: OR 4.35 [95% CI: 1.90-8.67], early awakening: OR 4.50 [95% CI: 1.97-8.97], and daytime sleepiness: OR 2.83 [95% CI: 1.25-5.56]). While nocturnal awakening and daytime sleepiness were not associated with EPS, the other types of sleep disturbance were independently positively associated with EPS and PDS. No association between self-reported sleep duration and FD was found. Sleep disturbance may be independently positively associated with the prevalence of FD among Japanese young people. Nocturnal awakening and daytime sleepiness were not associated with EPS; the other types of sleep disturbance were independently positively associated with EPS and PDS.

S496 Examining the Impact of the COVID-19 Pandemic on the Prevalence of Rome IV Functional Gastrointestinal Disorders

Introduction: It is well established that SARS-CoV-2 is an enteropathic virus that can lead to diarrhea, nausea, and vomiting, among other GI symptoms. Given the direct impact of SARS-CoV-2 on GI function, combined with the potential of the pandemic to negatively impact the gut-brain axis for some individuals via chronic stress and anxiety, we hypothesized that the prevalence of functional GI disorders (FGIDs) may have increased over time. To test our hypothesis, we conducted a series of cross-sectional surveys using Rome IV questionnaires during the pandemic in nationally-representative samples of >100,000 Americans. Methods: We conducted the initial online survey from 5/3-6/24/2020 during the peak of the initial coronavirus 2019 (COVID-19) wave in the US and followed it with monthly surveys starting in 3/2021 (latter stages of the pandemic). For each survey, a representative adult sample based on US Census age, sex, and region data was recruited. The initial survey included Rome IV questionnaires for irritable bowel syndrome (IBS), chronic idiopathic constipation (CIC), and opioid-induced constipation (OIC) along with demographic and comorbidity questions. In addition, the monthly follow-up surveys also included Rome IV questionnaires for functional dyspepsia, bloating, diarrhea, and unspecific bowel disorder. Our primary outcome was the prevalence of FGIDs and we used logistic regression to adjust for confounding. Differences in prevalence between time periods were considered significant when the 95% confidence intervals (CI) did not overlap. Results: Overall, 103,850 individuals completed the surveys. The Table presents the prevalence of Rome IV FGIDs vs pre-COVID-19 benchmarks reported by Palsson et al. and Sperber et al. (both also used internet-based surveys) in 2015 and 2017, respectively. The prevalence of IBS increased over time; Palsson et al. found that 4.7% (95% CI, 3.8%-5.7%) had IBS in 2015 while we noted that 8.4% (95% CI, 7.5%-9.2%) had IBS in 5/2021. The prevalence of functional dyspepsia also increased, as Sperber et al. reported a rate of 10.1% (95% CI, 8.8%-11.4%) in 2017 vs our finding of 17.7% (95% CI, 16.7%-18.8%) in 5/2021. The prevalence of CIC, OIC, and functional bloating, diarrhea, and unspecified bowel disorder remained stable over time. Conclusion: We found that the prevalence of IBS and functional dyspepsia increased by 75% compared to pre-COVID-19 estimates. We will continue to track the prevalence of FGIDs monthly over the next year to evaluate whether these changes persist.Table 1.: Prevalence of Rome IV FGIDs; data are presented as % (95% CI).

Функціональна диспепсія. Різні механізми, комплексне лікування

Функціональна диспепсія (ФД) є захворюванням з різними переважаючими патогенетичними механізмами. Поширеність ФД досить значно варіює — від 10 до 30 % населення залежно від країни й обстеженого контингенту. Виділяють дві форми ФД: постпрандіальний дистрес-синдром, що виявляється почуттям переповнення/раннього насичення після прийняття їжі, і синдром епігастрального болю — біль/печіння в епігастрії, які можуть посилюватися після їди. У значної частини пацієнтів з ФД зустрічаються прояви обох синдромів — так званий overlap, або змішаний варіант. В українській популяції всім хворим з диспепсією необхідно проводити діагностику і, при виявленні, обов’язкову ерадикацію H.pylori. У хворих із збереженою симптоматикою або спочатку не інфікованих бактерією, на нашу думку, як стартову терапію доцільно використовувати комбінацію «інгібітор протонної помпи + прокінетик». У нашій країні доступна фіксована комбінація омепразолу і домперидону в двох дозуваннях. Це Омез Д, що містить по 10 мг обох компонентів, і більш високодозований Омез ДСР, що містить 20 мг омепразолу і 30 мг домперидону у вигляді пелет сповільненого вивільнення.
