According to a meta-analysis of twin research studies, only a minority addressed gastrointestinal diseases, and mainly IBD and IBS. Here, we discuss similarities and differences between twin research in IBD and IBS, using these diseases as an example of the potential benefits that twin studies can offer gastroenterology.
