Background Corona virus has become a global health pandemic since its origin in Wuhan, China, in December 2019. The present systematic review and meta-analysis aims to assess gastrointestinal symptoms and liver enzymes trend in corona virus infection. Methods Pooled proportions were calculated using both fixed and random effects model. Weighted mean difference and 95% CI were calculated. Results We included 15 relevant articles in the meta-analysis (n = 3762). The pooled proportion of patients with nausea/vomiting was 7.00% (95% CI = 6.00-8.00) while that of diarrhea was 6.00% (95% CI = 5.00-7.00). Weighted mean difference of aspartate aminotransferase (AST), alanine aminotransferase (ALT) in non-severe COVID-19 patients was higher by 20.54 U/liter (95% CI = 19.95-21.13) and 21.38 U/liter (95% CI = 20.92-21.84) while that in severe patients was higher by 22.70 U/liter (95% CI = 19.09-26.45) and by 22.94 U/liter (95% CI = 20.46-25.42) respectively, as compared to general population. Pooled proportions showed ALT levels to be elevated in 16.00% (95% CI = 14.00-18.00) of patients with non-severe and 25.00% (95% CI = 20.00-31.00) of patients with severe COVID-19. Weighted mean difference of albumin and platelet count was found to be lower by 3.28 g/liter (95% CI = 3.05-3.50) and by 14.21 x 10(9)/liter (95% CI = 11.87-16.55) in non-severe patients and by 11.39 g/liter (95% CI = 10.16-12.63) and 40.70 x 10(9)/liter (95% CI = 33.62-47.77) in severe patients. Conclusions Our meta-analysis shows that patients with COVID-19 infection can present with nausea, vomiting and diarrhea in addition to elevated liver enzymes including AST, ALT and a decline in albumin and platelet count which is more marked in severe disease.
