The spectrum of gastrointestinal (GI) and liver diseases is recognized to have a geographical variation, which may be due to environmental or genetic differences. We aimed to explore this further in a specialist clinic serving a multi-ethnic Asian urban population. Methods A retrospective analysis of outpatient data from this institution's electronic medical records was conducted between January and June 2019. Clinical diagnoses of GI and liver diseases and associated demographic information were collected. Results Data from 3676 adult patients (median age 62 years, female 51.1%) were available for analysis. The frequency of luminal GI, liver and pancreato-biliary diseases were 34.2%, 63.2%, and 2.6%, respectively. Among luminal GI diseases, 38.6% were functional gastrointestinal disorders and 61.4% had an organic cause. A higher proportion of patients of Indian ethnicity were diagnosed with IBD compared with other ethnic groups (India 21.9%, Malay 16.5%, Chinese 12.2%, P = 0.001). Among liver diseases, the most common etiologies were HBV (44.4%) and NAFLD (39.3%). Cirrhosis and/or hepatocellular carcinoma were present in 18% of liver diseases, with NAFLD as the most frequent etiology. Among patients with NAFLD, a higher proportion of ethnic Malays and Indians were evident (Malay 53.8% vs Chinese 28.7% vs Indian 61.1%, P < 0.001). In contrast, a greater proportion of ethnic Chinese were diagnosed with HBV compared with other ethnic groups (Malay 30.9% vs Chinese 57.5% vs Indian 8.4%, P < 0.001). Conclusion The spectrum of GI and liver diseases has a peculiar epidemiology, particularly with reference to the ethnic predilection of certain diseases.
