Dyspepsia refers to group of upper gastrointestinal symptoms that occur commonly in adults. Dyspepsia is known to result from organic causes, but the majority of patients suffer from non-ulcer or functional dyspepsia. Epidemiological data from population-based studies of various geographical locations have been reviewed, as they provide more realistic information. Population-based studies on true functional dyspepsia (FD) are few, due to the logistic difficulties of excluding structural disease in large numbers of people. Globally, the prevalence of uninvestigated dyspepsia (UD) varies between 7%-45%, depending on definition used and geographical location, whilst the prevalence of FD has been noted to vary between 11%-29.2%. Risk factors for FD have been shown to include females and underlying psychological disturbances, whilst environmental/ lifestyle habits such as poor socio-economic status, smoking, increased caffeine intake and ingestion of non-steroidal anti-inflammatory drugs appear to be more relevant to UD. It is clear that dyspepsia and FD in particular are common conditions globally, affecting most populations, regardless of location.

Dyspepsia is a common gastroenterological problem with an estimated global prevalence between 7 and 40%. Functional dyspepsia (FD) is a major economic burden to patients and healthcare systems and significantly affects patient quality of life. The ROME III definition of FD divides it into two subgroups, epigastric pain syndrome and postprandial distress syndrome, the former being more associated with reflux disease and the latter with gastric dysmotility. The global incidence and prevalence of FD continues to rise, but the reason for this is not clear. Rising global obesity and gastroesophageal reflux disease rates may be contributing to the rise in FD. Socioeconomic and cultural demographic changes such as changing dietary habits and rapid urbanization, particularly in the developing countries, are likely to be influencing the course of FD and the way it presents.

Fulltext What indigestion means to the malays?

Lee YY, Chua AS

Despite being a large ethnic group within the South-East Asia, there is a paucity of reported literatures on dyspepsia in the Malay population. Recent population-based studies indicate that uninvestigated dyspepsia, based on the Rome II criteria, is reported in 12.8% and 11.6% of Malays in the urban and rural communities respectively. Organic causes of dyspepsia including upper gastrointestinal tract cancers, its precancerous lesions, and erosive diseases are uncommon which is largely due to an exceptionally low prevalence of Helicobacter pylori infection in this population. On the other hand, functional dyspepsia and irritable bowel syndrome are relatively common in the Malays than expected. Within a primary care setting, functional dyspepsia, based on the Rome III criteria, is reported in 11.9% of Malays, of which epigastric pain syndrome is found to be more common. Married Malay females are more likely to have functional dyspepsia and psychosocial alarm symptoms. Also based on the Rome III criteria, irritable bowel syndrome, commonly overlapped with functional dyspepsia, is reported in 10.9% of Malays within a community-based setting. Rather than psychosocial symptoms, red flags are most likely to be reported among the Malays with irritable bowel syndrome despite having a low yield for organic diseases. Based upon the above observations, "proton pump inhibitor test" is probably preferable than the "test and treat H. pylori" strategy in the initial management of dyspepsia among the Malays.

Can a non-invasive strategy for managing young dyspeptics be safely implemented in Asia?

Mahadeva S, Goh KL

PMID: 12653882

Dyspepsia is a common problem in the Asia-Pacific region, with a prevalence rate ranging from 10-20%. It constitutes 2-5% of consultations with primary-care physicians and forms a major part of the gastroenterologists' workload. Although upper gastrointestinal endoscopy (UGIE) is the investigation of choice, no serious disease is present in the majority of patients and various other ways have been suggested, mainly in the West, to reduce the demand on the finite resources of UGIE services. The alternative methods to UGIE have been based on non-invasive detection of Helicobacter pylori in patients with dyspepsia, as the organism has been shown to be associated with most peptic ulcers and even gastric cancer. A positive H. pylori test in a patient with dyspepsia may not necessarily indicate serious disease, but H. pylori eradication eliminates the propensity for developing peptic ulcers and perhaps even cancer (not proven). In high-risk populations, non-invasive screening for H. pylori can even be considered a 'cancer test', as it can help target investigations in a selected group of patients.

Clinically significant endoscopic findings in a multi-ethnic population with uninvestigated dyspepsia

Mahadeva S, Goh KL

Dig Dis Sci, 2012 Dec;57(12):3205-12.
PMID: 22688184 DOI: 10.1007/s10620-012-2256-7

INTRODUCTION: The proportion of clinically significant endoscopic findings (CSEF) in dyspepsia affects the initial management of this condition. With the changing epidemiology of organic upper gastrointestinal diseases in Asia, current data on CSEF remains uncertain.
METHODS: A cross-sectional study of consecutive adult patients attending an open access endoscopy list for the primary indication of dyspepsia was conducted. Independent epidemiological and clinical factors for CSEF were determined prospectively.
RESULTS: Data for 1167/1208 (96.6 %) adults (mean age 49.7 ± 15.9 years, 42.4 % males, ethnic distribution: 30.5 % Malays, 36.9 % Chinese and 30.8 % Indians) were analysed between January 2007 and August 2008. Three-hundred and eight (26.4 %) patients were found to have CSEF, most often those with age ≥45 years (30.3 vs 19 %, P < 0.0001), male gender (34.1 vs 20.7 % female, P < 0.0001), lower education levels (i.e. primary or no education), smoking (36.7 vs 24.9 %, P = 0.003), H. pylori infection (40.6 vs 21.8 %, P < 0.0001), and duration of dyspepsia ≤5 months (32.8 vs 24.4 %, P = 0.006). Age ≥ 45 years (OR 1.82, 95 % CI = 1.38-2.48), male gender (OR 1.84, 95 % CI = 1.53-2.59), H. pylori infection (OR 2.36, 95 % CI = 1.83-3.26), and duration of dyspepsia ≤5 months (OR 1.44, 95 % CI = 1.13-2.03) were subsequently identified as independent risk factors for CSEF.
CONCLUSION: CSEF are found in 26.4 % of Asian adults with uninvestigated dyspepsia. Duration of symptoms <5 months, among other recognised factors, is predictive of CSEF.

PLoS One, 2021;16(1):e0245511.
PMID: 33497382 DOI: 10.1371/journal.pone.0245511

BACKGROUND AND AIM: The association between body mass index (BMI) and functional gastrointestinal disorders (FGIDs) has been inconsistent. We aimed to explore the association of BMI with FGIDs in a primary care setting to provide more data in this area.
METHODS: A cross-sectional study of consecutive Asian adults attending a primary healthcare setting was conducted. This study was conducted in 2 phases: The association between BMI and common FGIDs (functional diarrhea/FD, irritable bowel syndrome/IBS, functional diarrhea and functional constipation/FC) was studied initially. The influence of anxiety and depression on BMI and FGIDs was additionally explored in phase 2.
RESULTS: A total of 1002 subjects (median age 32 years, 65.4% females, 90.7% Malay ethnicity, 73.2% higher than secondary level education) were recruited between August 2019 to January 2020. The majority of subjects were obese (39.2%), and had central obesity (51.7%), while 6.1% had metabolic syndrome. The prevalence of FD, IBS, functional diarrhea and FC were 7.5% (n = 75), 4.0% (n = 40), 1.2% (n = 12) and 10.5% (n = 105) respectively, based on the Rome III criteria. Among individual FGIDs, FD subjects had more underweight adults (BMI<18.5kg/m2) compared to controls (13.3% vs 3.5%, P = 0.002) and being underweight remained as an independent association with FD [OR = 3.648 (95%CI 1.494-8.905), P = 0.004] at multi-variate analysis. There were no independent associations between BMI and other FGIDs. When psychological morbidity was additionally explored, anxiety (OR 2.032; 95%CI = 1.034-3.991, p = 0.040), but not depression, and a BMI<18.5kg/m2 (OR 3.231; 95%CI = 1.066-9.796, p = 0.038) were found to be independently associated with FD.
CONCLUSIONS: FD, but not other FGIDs, is associated with being underweight. This association is independent of the presence of anxiety.

Clinical and epidemiological perspectives of dyspepsia in a multiracial Malaysian population

Dyspepsia is perhaps the most common gastrointestinal disease universally. The prevalence of dyspepsia ranges from 7-40% in population based studies worldwide. These figures vary with definition of dyspepsia used and also with the survey methodology. As with Western studies, functional dyspepsia (FD) predominates in Asia. With a decline in peptic ulcer disease and gastric cancer, the proportion of FD is set to increase further. Studies have shown FD to account for 50-70% of cases of uninvestigated dyspepsia. In Malaysia dyspepsia has been reported in up to 15% of a rural and 25% of an urban population. No racial differences were seen in the rural survey. In the urban survey, Malays and Indians were found to have significantly more dyspepsia than Chinese. No clear explanation can be found for these racial differences. In clinical practice, Malays seem to complain a lot of wind and bloating in the "stomach." This is interesting to note when you compare it with the prevalence of H. pylori which is distinctly less common amongst Malays compared to the Indians and Chinese. As with many Asian populations, many Malaysians do not consult for complains of dyspepsia. Many will self medicate and others may even bear with their complains. This is probably true in the rural population. Traditional medications are often used and these are often ethnic based. Different types of lotions for example are used for massaging the putative area in the abdomen by Malay, Chinese and Indian patients. Moxibustion and acupuncture is still practiced by Chinese traditional physicians for treatment of dyspepsia. The notion that mood disorders may underlies dyspepsia is still poorly accepted by a less educated or rural population who consider a psychiatric consultation a taboo. Amongst urban dwellers where Westernized medical care is readily available and the awareness of potential serious disease like cancer is higher, consultation for dyspepsia is certainly higher. Indeed a higher education level has been identified as independent risk factors for dyspepsia in both an urban and rural population survey in Malaysia. With greater consultation for dyspepsia, there has also been a higher demand and utilization of endoscopy services for investigation of gastrointestinal diseases in the country.

Anxiety, depression and quality of life differences between functional and organic dyspepsia

Mahadeva S, Goh KL

J Gastroenterol Hepatol, 2011 Apr;26 Suppl 3:49-52.
PMID: 21443710 DOI: 10.1111/j.1440-1746.2011.06656.x

OBJECTIVE AND BACKGROUND:
The role of psychological disturbance in the pathogenesis of functional dyspepsia is uncertain. We aimed to examine for differences in anxiety, depression and health-related quality of life (HRQOL) between adults with organic (OD) and functional dyspepsia (FD).

METHODOLOGY:
A prospective, cross-sectional study of Malaysian adults undergoing oesophago-gastro-duodenoscopy (OGDS) for the primary indication of dyspepsia was conducted. Prior to OGDS, locally translated and validated versions of the Hospital Anxiety and Depression Scale (HADS), Nepean Dyspepsia Index (NDI) and Leeds Dyspepsia Questionnaire (LDQ) were administered.

RESULTS:
839 patients (mean age 49.6 ± 15.8 years, 55.7% female, ethnic division: Malays 30.5% , Chinese 38.4%, Indians 29.4%) were studied between June 2008 and March 2009. 472 (56.3%) and 367 (43.7%) patients had FD and OD respectively. There was no difference in the mean LDQ score between FD and OD patients (18.6 vs 18.1, P = 0.4). Moderate/severe anxiety was more prevalent in FD compared to OD patients (28.5% vs 23.1%, P = 0.05) but there was no significant difference in depression. Summary scores for the NDI revealed a lower mean value in FD patients compared to OD patients (68.6 ± 19.5 vs 71.4 ± 19.6, P = 0.04).

CONCLUSION:
Patients with FD have a lower HRQOL compared to those with OD, but this could not be attributed to differences in anxiety nor depression between both groups.

PMID: 21649731 DOI: 10.1111/j.1440-1746.2011.06806.x

BACKGROUND AND AIM:
Outcome measures for clinical trials in dyspepsia require an assessment of symptom response. There is a lack of validated instruments assessing dyspepsia symptoms in the Asian region. We aimed to translate and validate the Leeds Dyspepsia Questionnaire (LDQ) in a multi-ethnic Asian population.

METHODS:
A Malay and culturally adapted English version of the LDQ were developed according to established protocols. Psychometric evaluation was performed by assessing the validity, internal consistency, test-retest reliability and responsiveness of the instruments in both primary and secondary care patients.

RESULTS:
Between April and September 2010, both Malay (n=166) and Malaysian English (n=154) versions were assessed in primary and secondary care patients. Both language versions were found to be reliable (internal consistency was 0.80 and 0.74 (Cronbach's α) for Malay and English, respectively; spearman's correlation coefficient for test-retest reliability was 0.98 for both versions), valid (area under receiver operating curve for accuracy of diagnosing dyspepsia was 0.71 and 0.77 for Malay and English versions, respectively), discriminative (median LDQ score discriminated between primary and secondary care patients in Malay (11.0 vs 20.0, P<0.0001) and English (10.0 vs 14.0, P=0.001), and responsive (median LDQ score reduced after treatment in Malay (17.0 to 14.0, P=0.08) and English (18.0 to 11.0, P=0.008) to dyspepsia.

CONCLUSIONS:
The Malaysian versions of the LDQ are valid, reliable and responsive instruments for assessing symptoms in a multi-ethnic Asian population with dyspepsia.

Scand. J. Gastroenterol., 1991 Nov;26(11):1123-31.
PMID: 1754846

A study was undertaken to determine the role of Helicobacter pylori in non-ulcer dyspepsia (NUD) and to determine the efficacy of colloidal bismuth subcitrate (CBS) in the treatment of NUD. Seventy-one patients were randomly allocated (double blind) to CBS or placebo, two tablets twice daily for 4 weeks. The severity of dyspepsia was scored and endoscopies performed before and after treatment, and antral biopsy specimens were taken for bacteriologic and histologic examination. Forty patients had H. pylori infection, and all had changes of chronic active gastritis. H. pylori was cleared from 17 to 21 patients (81%) treated with CBS, whereas none of the 19 patients treated with placebo cleared the bacteria. Improvement in histology was noted in 15 of 21 patients (71.4%) treated with CBS, whereas no improvement was noted in any of the placebo controls. Thirty-one patients were negative for H. pylori. All had either normal gastric histology or minor degrees of inflammation. Seventeen of these patients received CBS, and 14 received placebo. All groups reported improvement in the symptom score; however, the H. pylori-positive, CBS-treated group recorded a significantly higher improvement than the other groups (p less than 0.001). Relapse of H. pylori infection after initial clearance of the bacteria was high. Twelve of 16 patients evaluated relapsed 1 month after withdrawal of CBS.

Malrotated Subhepatic Caecum with Subhepatic Appendicitis: Diagnosis and Management

Chong HC, Chai FY, Balakrishnan D, Asilah SM, Adila IN, Syibrah KZ

Case Rep Surg, 2016;2016:6067374.
PMID: 27648337

Subhepatically located caecum and appendix is a very rare entity. It occurs due to the anomaly in fetal gut rotation that results in an incomplete rotation and fixation of the intestine. Appendicitis, which is a common surgical emergency, in combination with the abnormal subhepatic location, presents a great challenge in its diagnosis and management. Here, we describe a 42-year-old male with chronic dyspepsia who presented with sepsis and severe pain at his right hypochondriac and epigastric region. The final diagnosis was acute appendicitis of the subhepatic appendix. Our discussion focuses on the diagnostic approach and clinical and surgical management. We hope that our report will increase the awareness among the clinicians and hasten the management of such rare condition to avoid complications.

Neurogastroenterol Motil, 2016 Feb;28(2):167-74.
PMID: 26331919 DOI: 10.1111/nmo.12657

Functional dyspepsia (FD) is a common condition, affecting adults in both Western (North America and Europe) and Eastern (Asian) parts of the globe. The prevalence has been reported to range from 5% to 40%, largely due to variation from definition criteria and geographical location. Recent published reports in Western and Eastern populations separately indicate that differences in the epidemiology and clinical patterns of FD may exist. Such differences will have implications for the clinical management of and healthcare strategizing for FD at the local level.

Fulltext Investigating functional dyspepsia in Asia

Lee YY, Chua AS

J Neurogastroenterol Motil, 2012 Jul;18(3):239-45.
PMID: 22837871 DOI: 10.5056/jnm.2012.18.3.239

The diagnosis of functional dyspepsia (FD) is challenging since it depends largely on symptoms which are often heterogeneous and overlapping. This is particularly so in Asia with many different cultures and languages. Symptom-based diagnosis of FD based on Rome III criteria has not been fully validated and it may not be suitable in some Asian populations. Clinicians often assume that investigations in FD are not rewarding and physiological tests are often not available unless in the research setting. Investigation of alarm features and role of Helicobacter pylori in FD remain controversial but experts agreed that both should be tested. Physiological tests including gastric accommodation and chemical hypersensitivity tests are underutilized in Asia and available studies were few. While experts do not recommend routine clinical use of gastric accommodation tests but they agree that these tests can be advocated if clinically indicated. Empiric therapeutic trial is not currently a diagnostic option. The pathogenesis of FD is still poorly understood and there is a substantial placebo response. As a conclusion, a diagnosis of FD is challenging especially so in the context of Asia and despite the limitations of available physiological tests experts agreed that these tests can be advocated if and when clinically indicated.

Fulltext The impact of dyspepsia on symptom severity and quality of life in adults with headache

Tai ML, Norhatta N, Goh KJ, Moy FM, Sujarita R, Asraff AA, et al.

PLoS One, 2015;10(1):e0115838.
PMID: 25629323 DOI: 10.1371/journal.pone.0115838

BACKGROUND: Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache.
METHODS: A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone.
RESULTS: 280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0 ± 17.3 years, 57.0% females and ethnic distribution-Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39-5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67 ± 22.85 mm vs 51.20 ± 24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82 ± 0.18 vs 0.90 ± 0.16, p = 0.037 and EQ-5D VAS 62.08 ± 17.50 mm vs 72.62 ± 18.85 mm, p = 0.018), compared to those without dyspepsia.
CONCLUSION: Dyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache.

Mandarin version of the Leeds Dyspepsia Questionnaire: A valid instrument for assessing symptoms in Asians

Leow HR, Ching SM, Sujarita R, Yap CF, Chia YC, Ho SH, et al.

J Dig Dis, 2014 Nov;15(11):591-6.
PMID: 25139629 DOI: 10.1111/1751-2980.12183

OBJECTIVE:
To develop and validate a Mandarin version of the Leeds Dyspepsia Questionnaire (M-LDQ) in Asian patients with dyspepsia.

METHODS:
The M-LDQ was developed according to standardized methods. The validity, internal consistency, test-retest reliability and responsiveness of the instrument were evaluated in both primary and secondary care patients.

RESULTS:
A total of 184 patients (mean age 54.0 ± 15.8 years, of whom 59% were women and 72.3% of whom had at least secondary level education) were recruited between August 2012 and March 2013, from both primary (n = 100) and secondary care clinics (n = 84). Both the internal consistency of all components of the M-LDQ (Cronbach's α 0.79) and test-retest reliability (Spearman's correlation coefficient 0.78) were good. The M-LDQ was valid in diagnosing dyspepsia in primary care (area under the receiver operating characteristics curve 0.84) and was able to discriminate between secondary and primary care patients (median cumulative LDQ score 13.0 vs 3.0, P < 0.0001). Among eight patients with organic dyspepsia, the median M-LDQ score reduced significantly from 21.0 (pretreatment) to 9.5 (4 weeks post-treatment) (P < 0.0001).

CONCLUSION:
The M-LDQ is a valid and responsive instrument for assessing ethnic Chinese adults with dyspepsia.

Campylobacter pylori infection: experience in a multiracial population

Goh KL, Peh SC, Wong NW, Parasakthi N, Puthucheary SD

J Gastroenterol Hepatol, 1990 5 1;5(3):277-80.
PMID: 2103410

Over a 15-month period, 399 patients with dyspepsia were investigated for the presence of Campylobacter pylori infection. Half of the patients (50.6%) had Campylobacter organisms in the antrum of the stomach. C. pylori was found in 96.1% of patients with histological changes of chronic active gastritis in the antrum. Of patients with duodenal and gastric ulcers, 87.8% and 87.5%, respectively, had Campylobacter organisms, as did 39.3% of patients with non-ulcer dyspepsia. C. pylori infection was most commonly found in Chinese and Indians. Although the prevalence of infection appeared to increase with age, there was an equal distribution amongst the sexes.
