Core Tip	In this nationwide population-based study, we showed that the incidence of inflammatory bowel disease (IBD) was higher in chronic obstructive pulmonary disease (COPD) patients compared to age-and sex-matched controls without IBD in South Korea. And the risk of developing IBD also increased as the severity of COPD increased. It is important to be aware of the gastrointestinal symptoms indicative of IBD in COPD patients. Accurate clinical assessment should be done, especially in patients with severe COPD in order to prevent complications and avoid excess medical expenses.
