There have been numerous studies who aim to establish the link between bad gut health and mental health problems. While not all mental health problems are caused by the gut, the gut can trigger these issues such as anxiety and depression.

That doesn't mean, however, that functional gastrointestinal conditions are imagined or "all in your head." Psychology combines with physical factors to cause pain and other bowel symptoms. Psychosocial factors influence the actual physiology of the gut, as well as symptoms. In other words, stress (or depression or other psychological factors) can affect movement and contractions of the GI tract.”
