Findings from a fascinating 2016 study in Bipolar Disorders are just one piece in a mounting library of evidence that the gut is intricately tied to the brain in ways that were never understood. The study reports that people who were hospitalized for mania associated with serious mental disorders were more likely to be on antibiotics to treat active infections than a group of people without a mental disorder. 

This single study cannot, of course, indicate that antibiotics are the cause of these disorders, and we would not suggest that they do. Johns Hopkins’ own publication on the study put it quite well:  

Although the researchers caution that their study does not suggest cause and effect, they note that it does suggest that an infection, use of antibiotics or other factors that change the body’s natural collection of gut and other bacteria may individually or collectively contribute to behavioral changes in some people with mental disorders. 

The connection between the gut and the brain, known as the Gut-Brain Axis, and the unique microbiome each person has, all play an integral part in the ebb and flow of health, emotions, and even behavior. Did you know, for example, that about 90% of our serotonin and 50% of our dopamine are actually made in the gut
