Researchers confirm genetic link between depression and common gut disorder

“Using genetic analysis you can look at that more closely, and our analysis suggests there is definitely a relationship there.”

Peptic ulcers had been thought to be caused solely by stress for many years, until Nobel prize-winning work by Australian researchers Barry Marshall and Robin Warren identified a link to the bacteria H. pylori.

Professor Wray says the new results do not invalidate that work, but demonstrates that there is not just one factor that leads to a disease manifesting, and that the real picture is far more complex.

“The key thing that came out in our genetic analysis of peptic ulcer disease is demonstrating that there’s host factors, things in our genetics, which make some people more susceptible to the…
