Recently while browsing the internet, I came across many forum threads discussing the link between acid reflux, GERD and depression.
In fact, one of the forum members asked whether anyone had had acid reflux as some of the early symptoms of depression? Well, I would raise my hand for that and say yes.
An observational study published in the Scandinavian Journal of Gastroenterology, 2002 revealed a strong link between gastric symptoms, anxiety and depression. 
Four stomach health symptoms were evaluated in the study- heartburn, nausea, diarrhoea and constipation. 48% of the study population had one or more of these symptoms.
15.3% had an anxiety disorder while 10.4% had depression. Anxiety was found to be associated with all four stomach health symptoms but it was strongly linked to nausea. Depression was less strongly associated with all four gut health symptoms.
In this post, we will be going over the research that aims to identify the possible link between acid reflux, depression and anxiety.
