Background:
Irritable bowel syndrome (IBS) is a common functional gastrointestinal (GI) disorder. Several studies have analyzed the long-term GI symptoms and IBS following coronavirus disease 2019 (COVID-19). The purpose of this study is to evaluate the incidence and predisposing factors for IBS following COVID-19 by a systematic review and meta-analysis.
Methods:
Electronic databases were searched to identify relevant studies. Primary outcomes were the pooled incidence rate of IBS following COVID-19 and the pooled relative risk (RR) for IBS in the COVID-19 group compared to the non-COVID-19 group. Secondary outcomes were the pooled RR and the standardized mean difference (SMD) for predisposing factors in the IBS group compared to the non-IBS group. Heterogeneity was evaluated using Cochran's Q test and I2 statistics.
Results:
Ten studies were included in this study. The pooled incidence rate of IBS in COVID-19 patients was 12%. The pooled incidence rate of IBS-D, IBS-C and IBS-M was 5%, 2% and 1%. The pooled incidence rate of IBS in 6 and 12 months was 10% and 3%. The pooled RR for IBS in COVID-19 patients was 1.23 [95% confidence interval (CI) = 0.50-3.01] compared to non-COVID-19 patients. The pooled RR or SMD for mild, moderate, and severe disease activity, procalcitonin (PCT), depression or anxiety in IBS patients following COVID-19 was 0.94 (95% CI = 0.74-1.21), 1.19 (95% CI = 0.65-2.21), 1.30 (95% CI = 0.63-2.66), 6.73 (95% CI = 6.08-7.38) and 3.21 (95% CI = 1.79-5.75).
Conclusion:
The incidence of IBS following COVID-19 was 12%. But it was not higher than the general population. We also found some predisposing factors for IBS including depression or anxiety, PCT.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
